Oculus Rift
The Oculus Rift is a pioneering virtual reality (VR) headset developed by Oculus VR, designed to provide immersive, high-fidelity experiences primarily for gaming but also applicable to simulation, training, and entertainment.[1] Founded in 2012 by entrepreneur Palmer Luckey, the company launched a groundbreaking Kickstarter crowdfunding campaign on August 1, 2012, which raised $2.4 million to fund development of the device after Luckey built early prototypes using modified consumer electronics.[2] This success propelled Oculus VR forward, leading to its acquisition by Facebook (now Meta Platforms) on March 25, 2014, for approximately $2 billion in cash and stock, a move that accelerated VR's integration into mainstream technology ecosystems.[3] The consumer version, Oculus Rift CV1, launched on March 28, 2016, as the first major PC-tethered VR headset of the modern era, featuring dual OLED displays with 1080 × 1200 resolution per eye, a 90 Hz refresh rate, and an approximately 110° horizontal field of view to minimize motion sickness and enhance presence.[4][5] It incorporated 6 degrees of freedom (6DoF) tracking via an external sensor and Constellation software, allowing users to move their head and body naturally within a virtual environment while blocking out the real world for full immersion.[5] Priced at $599 upon release, the Rift required a compatible high-end PC with at least an Intel i5-4590 processor, NVIDIA GTX 970 GPU, and 8 GB RAM, positioning it as an accessible yet powerful entry into VR for enthusiasts and developers.[6] The Oculus Rift's introduction marked a pivotal revival of VR technology, which had languished since earlier experimental efforts in the 1990s, by delivering low-latency visuals and precise tracking that addressed longstanding issues like simulator sickness.[7] Widely regarded as the device that kickstarted the contemporary VR industry, it spurred investments exceeding billions of dollars and inspired competitors like HTC Vive and PlayStation VR, while enabling applications in fields such as medical training, architectural design, and social interaction.[7][8] Although succeeded by standalone models like the Oculus Quest series, the Rift's legacy endures as the foundational hardware that democratized immersive computing.[9]History
Founding and Early Prototypes
Palmer Luckey, a 19-year-old virtual reality enthusiast based in Long Beach, California, developed a passion for VR technology during his teenage years, amassing a collection of over 50 vintage VR headsets and displays from the 1990s. Working in his parents' garage, Luckey began constructing his own prototypes in 2011, driven by dissatisfaction with the low field of view and high latency of existing consumer VR devices. His initial proof-of-concept, known as the PR1, featured a 5.6-inch LCD screen from a mobile phone mounted inside a frame made from ski goggles, creating a rudimentary head-mounted display that demonstrated the potential for immersive VR experiences.[10][7] The PR1 prototype incorporated key innovations to address common VR shortcomings, including a 90-degree field of view achieved through simple magnifying lenses placed in front of the display, which significantly expanded peripheral vision compared to prior headsets. It also utilized low-latency head tracking powered by a MEMS gyroscope, enabling responsive orientation sensing with minimal delay to reduce disorientation; this design drew inspiration from graphics expert Michael Abrash's earlier research on VR perception and motion simulation at Valve. These features marked a departure from the bulky, low-resolution systems of the past, prioritizing comfort and immersion in a form factor weighing around 6-7 pounds.[7][11] In early 2012, Luckey began demonstrating his prototypes at informal VR enthusiast meetups in Silicon Valley, where they garnered attention from industry figures. Notably, id Software co-founder John Carmack received an early unit and conducted extensive testing, praising its potential while advising on the integration of low-persistence OLED displays to minimize motion blur and alleviate motion sickness—a persistent issue in early VR. Carmack's feedback, shared during hands-on sessions and public demos like those at E3 2012, helped refine the technology's focus on high refresh rates and precise tracking.[12][13][14] These early efforts culminated in the formal incorporation of Oculus VR Inc. in April 2012, with entrepreneur Brendan Iribe joining as CEO to provide business leadership and secure initial funding. Iribe, previously CEO of Scaleform, brought experience in game development tools and helped transition the project toward commercialization, setting the stage for broader development.[7][15]Kickstarter Campaign and Funding
The Oculus Rift Kickstarter campaign launched on August 1, 2012, with a funding goal of $250,000 to support the development of a virtual reality headset aimed at immersive gaming experiences.[16] The project rapidly gained traction, surpassing its target within hours and ultimately raising $2,437,429 from 9,522 backers over the 30-day campaign period.[17] This overwhelming success enabled Oculus VR to incorporate enhancements such as improved optics for a wider field of view, integrated head tracking for low-latency movement, and the creation of a software development kit (SDK) to facilitate developer integration.[18] The substantial backing transformed the initiative from a prototype demonstration into a viable commercial venture, attracting further institutional investment. In June 2013, Oculus VR secured $16 million in Series A funding, co-led by Spark Capital and Matrix Partners, with additional participation from Founders Fund and Formation 8.[19] This was followed by a $75 million Series B round in December 2013, led by Andreessen Horowitz and including investments from Spark Capital, Matrix Partners, and Formation 8.[20] These funds accelerated hardware refinement and expanded the team's capacity to produce development kits. The first batch of 1,000 units pledged by Kickstarter backers—designated as the Development Kit 1 (DK1)—began shipping in late March 2013, with full delivery to all backers completed by May.[21]Development Kits
The Oculus Rift's development began with the Developer Kit 1 (DK1), funded through a successful Kickstarter campaign launched in August 2012 and shipped starting in March 2013 to backers and select developers.[22] This initial kit featured a 7-inch LCD display with a resolution of 640×800 pixels per eye, a 60 Hz refresh rate, and 16 ms persistence to mitigate motion blur.[23] Despite these advancements over prior prototypes, the DK1 exhibited noticeable issues, including a prominent screen door effect due to visible pixel gaps and frequent motion sickness from high latency and limited head tracking confined to rotation only.[24] Building on developer feedback from early testing, Oculus announced the Developer Kit 2 (DK2) at the Game Developers Conference (GDC) in March 2014, with shipments beginning in July 2014.[25] The DK2 introduced OLED panels for better contrast and color, a higher resolution of 960×1080 per eye at 75 Hz, and low-persistence displays with approximately 2 ms scanout time to further reduce blur.[26] Key enhancements included asynchronous timewarp, a software technique integrated with the hardware to interpolate frames and lower perceived latency, alongside positional tracking enabled by an infrared camera detecting LED markers on the headset for 6 degrees of freedom movement.[27] In January 2014, prior to the DK2's release, Oculus unveiled the Crystal Cove prototype at CES, showcasing significant hardware refinements informed by ongoing developer input.[28] This non-commercial unit featured higher-resolution displays at 1080×1920 per eye using low-persistence OLED panels to minimize motion sickness and blur, along with integrated audio for simplified setup.[29] Positional tracking was enhanced through an external camera monitoring over two dozen infrared reflectors on the headset, allowing lean-in interactions and reducing disorientation compared to earlier kits. The evolution continued with the Crescent Bay prototype, demonstrated at the inaugural Oculus Connect developer conference in September 2014 but never offered for public sale.[30] It incorporated a 90 Hz refresh rate for smoother visuals, introduced early versions of Oculus Touch controllers for hand tracking, and featured improved ergonomics with lighter weight distribution and adjustable straps to address comfort complaints from prior iterations.[31] These prototypes benefited from iterative feedback loops, including beta testing sessions and events like GDC and Oculus Connect, where developers highlighted needs for better lenses to reduce distortion and more precise tracking to enhance immersion.[4]Consumer Releases
The Oculus Rift CV1 marked the transition from developer-focused hardware to a consumer product, building on the capabilities demonstrated by prior development kits. Announced at E3 2015 with hands-on demonstrations, it represented Oculus's first major push into retail VR.[32] The CV1 launched on March 28, 2016, at a price of $599, shipping to over 20 countries initially.[33] It featured OLED displays with 1080 × 1200 resolution per eye and a 90 Hz refresh rate, paired with the Constellation tracking system that relied on external infrared sensors for precise 6DoF movement detection.[34] Production of the CV1 involved assembling over 200 custom components per unit to achieve high-quality manufacturing standards.[35] To drive adoption, Oculus bundled the headset with popular titles such as EVE: Valkyrie, a multiplayer space combat game optimized for VR, included with every unit at launch.[36] Early sales were strong for a nascent VR market, with estimates placing shipments at around 243,000 units for the Rift in 2016 when combined with competitor data, though Oculus did not release official figures. In 2019, Oculus introduced the Rift S as an updated consumer offering, released on May 21 at $399 to broaden accessibility.[37] Co-developed with Lenovo to incorporate expertise in display and ergonomics, the Rift S shifted to LCD panels with 1280 × 1440 resolution per eye and an 80 Hz refresh rate.[38] A key upgrade was inside-out tracking powered by five integrated cameras, enabling setup without external sensors and simplifying user onboarding.[39] Positioned as a mid-cycle refresh, the Rift S arrived amid Oculus's growing emphasis on standalone VR devices like the Quest, reflecting a strategic pivot toward wireless, PC-independent experiences while maintaining PC-tethered high-fidelity VR.[40] Sales of the Rift S were more modest, with approximately 71,000 units sold in Q4 2019 alone, though Oculus did not release full-year figures.[41]Discontinuation and Legacy Developments
At Facebook Connect in September 2020, Oculus announced that it would cease development of new PC-tethered virtual reality hardware, with sales of the Rift S set to conclude in 2021, shifting focus entirely to standalone headsets like the Quest series.[42] This marked the effective end of the Rift product line's active production phase, as the company emphasized the growing accessibility of wireless VR over tethered PC-dependent systems.[43] The official discontinuation progressed in 2021, with the Rift S being removed from the Oculus store in July, making it unavailable for new purchases through official channels.[44] Support for the original Oculus Rift CV1 tapered gradually thereafter, with the last major software update, version 28, released in late 2020 to align with platform-wide enhancements before the pivot.[45] Key factors driving this decision included the high barriers of the PC VR ecosystem—such as the need for powerful, expensive hardware—and the surging popularity of the wireless Quest 2, launched in October 2020, which quickly outsold all prior Oculus headsets combined by early 2021.[46] Supply chain disruptions during the COVID-19 pandemic further accelerated the transition away from complex tethered setups.[47] As of November 2025, the Rift line maintains legacy status with ongoing software support through the Meta PC app for existing hardware owners, ensuring compatibility with PC VR content including SteamVR applications, though no new features or hardware integrations are being developed. New setups remain possible for the CV1 and Rift S.[45] This sustained but minimal support underscores Oculus's strategic emphasis on standalone VR, allowing the Rift to serve as a bridge for legacy PC VR users amid the broader evolution of the ecosystem.[45]Hardware
Original Oculus Rift (CV1)
The Original Oculus Rift (CV1) represented a significant evolution from earlier prototypes like the DK2, refining the design for consumer use with enhanced tracking precision and comfort features. The headset's build consisted of a lightweight plastic shell weighing approximately 470 grams, which helped reduce strain during sessions but was balanced by an adjustable head strap for better distribution. It included an interchangeable facial interface made of foam padding to fit various face shapes and improve hygiene, along with mechanical lens sliders for inter-pupillary distance (IPD) adjustment ranging from 58 mm to 72 mm, allowing users to align the optics precisely to their eyes for sharper visuals and reduced eye strain. At the core of the visual experience were dual 5.6-inch OLED panels, each with a resolution of 1080 × 1200 pixels, delivering a combined 2160 × 1200 resolution and a 90 Hz refresh rate to minimize motion blur and latency. These displays achieved a 110-degree horizontal field of view through asymmetric Fresnel lenses, which magnified the image while keeping the headset compact and lightweight, though they introduced some edge distortion known as the "god rays" effect in high-contrast scenes. The optics were tuned for low persistence, enhancing clarity during head movements and contributing to a sense of presence in virtual environments.[5] The Constellation tracking system utilized external infrared LED sensors connected via USB, with the bundle including two sensors to provide 6 degrees of freedom (6DoF) positional and rotational tracking for the headset and controllers within a recommended play space of up to 5 m × 5 m. These sensors illuminated infrared LEDs on the headset and controllers, using computer vision algorithms to map movements with sub-millimeter accuracy and low latency, supporting room-scale experiences without base stations. This setup allowed for natural interaction, such as leaning or stepping around virtual objects, though optimal performance required careful sensor placement to avoid occlusion. Additional sensors could be added up to four for expanded coverage.[48] Audio was delivered through integrated over-ear headphones with 3D spatial sound capabilities, driven by a CMedia CM119BN USB audio controller, which provided immersive binaural audio synced to head orientation for heightened environmental awareness. Regarding comfort, the forward-weighted design—due to the displays and electronics—often led to neck fatigue after 1-2 hours of continuous use, prompting users to take breaks or employ aftermarket counterweights for better balance. Studies on head-mounted displays confirm that such weight distribution impacts physical load, with fatigue increasing as the center of mass shifts anteriorly.[49] The Oculus Touch controllers, bundled with the CV1 bundle, were asymmetric wireless remotes tracked via the Constellation system, featuring capacitive sensors on the grips and triggers to detect finger presence without full hand tracking. Each controller included dual analog thumbsticks for precise navigation, A/B/X/Y face buttons, and ergonomic grips molded for natural hand positioning, enabling gesture-based interactions like pointing or grabbing in VR applications. These elements combined to create an intuitive user experience, though battery life limited sessions to about 6-8 hours.[48]Oculus Rift S
The Oculus Rift S, released in 2019, represents Oculus's second-generation PC-tethered VR headset, emphasizing simplified setup and enhanced comfort through key hardware refinements over the original CV1 model.[50] It adopts an inside-out tracking approach and LCD displays to address previous limitations in sensor dependency and motion artifacts, while maintaining compatibility with existing PC VR ecosystems.[51] Priced at $399 and bundled with Oculus Touch controllers, it targeted users seeking a more accessible entry into high-fidelity VR without external base stations.[37] The Rift S retains a similar ergonomic shell to the CV1 but introduces a halo-style head strap for improved weight distribution and stability, directly responding to common comfort complaints about the predecessor's fabric strap during extended sessions.[52] This rigid, adjustable band better balances the headset's 609-gram weight across the forehead and occiput, reducing pressure points on the face.[53] Additionally, it features a flip-up visor mechanism, allowing users to quickly access a direct real-world view without fully removing the device, which enhances usability in shared spaces or during breaks.[54] For visuals, the Rift S employs a single fast-switch LCD panel divided between the eyes, delivering 1280×1440 resolution per eye at an 80 Hz refresh rate.[39] This LCD implementation minimizes the black smearing common in OLED panels during fast motion, providing clearer contrast in dynamic scenes, though it sacrifices some of OLED's infinite blacks for a more consistent backlight.[53] The optics include improved Fresnel lenses with a 110° horizontal field of view and fixed IPD of approximately 62 mm (with software adjustment options), reducing edge distortion and the screen-door effect compared to the prior model.[51] Tracking on the Rift S relies on five embedded infrared cameras for inside-out 6DoF (six degrees of freedom) positional and rotational sensing, eliminating the need for the CV1's external Constellation sensors and simplifying room-scale setup.[50] This camera array enables precise head and hand tracking within a 5×5-meter play area, with the integrated Guardian system allowing users to define virtual boundaries via an initial calibration scan, promoting safety by alerting to potential collisions.[52] Passthrough functionality leverages these cameras for a real-time, low-resolution monochrome view of the environment, accessible on demand for quick environmental checks.[55] Audio integration consists of integrated spatial audio speakers positioned in the head strap, offering enhanced spatial clarity and immersion over the CV1's headphones, with reduced sound leakage for private use.[56] These drivers support 3D audio rendering through the Oculus platform, providing directional cues that align with tracked movements.[51] The Rift S fully supports the Oculus Touch controllers introduced with the CV1, ensuring seamless compatibility with the existing library of over 1,000 PC VR titles without requiring new peripherals.[37] This backward compatibility preserves the controllers' 6DoF tracking and haptic feedback, allowing immediate access to games and experiences optimized for the Touch hardware.[50]Accessories and Variants
The Oculus Touch controllers, released in December 2016 alongside the consumer version of the Rift CV1, are motion-tracked hand controllers designed to provide natural hand presence in virtual environments.[9] These controllers feature six degrees of freedom (6DoF) tracking for precise positional and rotational movement, along with thumbsticks, capacitive touch sensors on buttons, and integrated haptic feedback to simulate tactile interactions such as vibrations during gameplay.[57][58] They connect via USB and are powered by AA batteries, enabling room-scale experiences when paired with the Rift's Constellation tracking system.[59] For the CV1 model, additional Constellation sensors were available as official accessories to expand tracking coverage beyond the standard two-sensor setup, supporting larger play areas up to room-scale (approximately 2.5m x 2.5m) by reducing occlusion and improving 360-degree tracking accuracy.[60] Each extra sensor, sold individually or in bundles, includes a USB 2.0 extension cable for flexible placement on desks, walls, or stands, though up to four could be used for optimal performance in complex setups.[61] DisplayPort and USB 3.0 extension cables were also offered officially to allow greater distance from the PC without signal degradation, facilitating setups in bigger rooms.[62] Audio accessories for the Rift lineup emphasized comfort and immersion. The Deluxe Audio Strap for the CV1, an official upgrade released in 2016, replaced the standard fabric strap with an adjustable halo-style band incorporating removable over-ear headphones for superior sound isolation and bass response compared to the bundled earbuds.[63] In contrast, the Rift S featured integrated stereo speakers embedded in its halo headband, providing spatial audio directly from the device without the need for separate headphones, though a 3.5mm jack allowed for wired alternatives.[64][39] While Oculus did not produce official headset variants, third-party accessories expanded compatibility and customization. For instance, limited-edition bundles like the ASUS ROG Strix PC paired with the Rift CV1 were offered in 2016 for optimized performance, including pre-configured hardware meeting Oculus-ready specifications.[65] The Rift systems, particularly the CV1 and Rift S, are compatible with Valve Index controllers through SteamVR, requiring Lighthouse base stations for tracking but enabling cross-platform use in supported titles.[66] No new official Rift-specific accessories have been developed since the 2021 discontinuation of the line, but items like Touch controllers, sensors, and straps remain available through resellers and third-party vendors as of 2025, with ongoing support for legacy hardware via software updates.[45][67]Software
Oculus Runtime and SDK
The Oculus PC Runtime serves as the foundational software layer for the Rift ecosystem, installed through the Oculus desktop application and responsible for interfacing between the hardware sensors, the operating system, and VR applications. It performs sensor fusion by integrating data from the headset's inertial measurement unit (IMU), magnetometer, and tracking cameras to deliver precise six-degrees-of-freedom head tracking with low latency. Additionally, the runtime manages rendering pipelines, including barrel distortion correction to counteract the optical aberrations introduced by the headset's wide-field-of-view lenses, ensuring immersive stereoscopic visuals. Versions of the runtime began with 0.4.1 in support of the Developer Kit 1 (DK1) in 2014 and have progressed iteratively, reaching v81.0 by October 2025, with each update incorporating hardware compatibility enhancements and performance refinements.[68][69] The Oculus SDK, built primarily as a C/C++ application programming interface (API), enables developers to embed Rift-specific VR capabilities into custom software, from games to simulations. Core to its functionality is the LibOVR library, which abstracts hardware interactions and provides utilities like OVRLatencyTest, a diagnostic tool for quantifying motion-to-photon latency—measuring the time from head movement detection to pixel display on the screens—to help optimize application performance.[70][71] Central to the SDK's performance optimizations are Timewarp and Spacewarp technologies, which mitigate frame drops and latency in dynamic VR environments. Timewarp reprojects the most recent rendered frame using updated head pose data at the compositor stage, enabling asynchronous updates to maintain smooth visuals even if application rendering exceeds target frame times, originally introduced in SDK 0.3.1 and refined in subsequent releases. Spacewarp, an extension of this approach, generates intermediate frames by extrapolating motion vectors from prior renders, effectively doubling perceived frame rates (e.g., from 45 Hz to 90 Hz) for compatible content while preserving scene integrity. Foveated rendering capabilities dynamically allocate higher pixel densities to the foveal region of the gaze—typically the central 10-20 degrees—while reducing resolution in peripheral areas, yielding up to 30% GPU savings without noticeable quality loss in high-fidelity applications.[72][73][74] Supporting these features are dedicated developer tools, including the Oculus Integration asset for Unity and the Meta XR Integration for Unreal Engine, which provide pre-built plugins for seamless API access, input handling, and spatial audio integration within these popular engines. The Oculus Debug Tool complements these by offering runtime configuration options, such as pixel density overrides (ranging from 0.5 to 2.0), enabling supersampling to sharpen visuals by rendering at higher internal resolutions before downsampling to the display, thus reducing aliasing in demanding scenes.[75][76][77]Oculus Home and Store
Oculus Home served as the primary virtual reality dashboard for the Oculus Rift, debuting with the consumer version (CV1) in March 2016. This immersive interface acted as a central hub within VR, enabling users to navigate menus, launch applications, and manage their content library through gesture-based controls and spatial interactions. Built on the Oculus Runtime software for seamless performance, it provided quick access to apps via a desktop-like overlay or full VR environment, reducing the need to exit VR sessions frequently.[5] The environment was designed for personalization, evolving from a default space station theme to support customizable setups starting in late 2017. Users could decorate their Home with hundreds of themed items, furniture, and decorations from an official library, or import custom 3D models in .glb format to create tailored virtual spaces. This feature emphasized user ownership, allowing individuals to craft relaxing or thematic areas that reflected their preferences. Social capabilities were integrated in 2018, permitting up to eight users— the host plus seven invited friends—to gather in the same Home for shared activities like voice chat or co-viewing streamed desktop content. These parties enhanced connectivity, though editing was temporarily locked during visits to maintain stability.[78][79] The Oculus Store, integrated directly into Oculus Home, launched in 2016 as the dedicated digital marketplace for Rift content. It featured exclusive titles such as Lone Echo, a zero-gravity narrative adventure developed by Ready at Dawn and published by Oculus Studios, which highlighted the platform's focus on high-quality, immersive experiences. The store offered diverse content types, including free demos for sampling gameplay and paid games priced typically between $20 and $60, alongside subscription-based partnerships for ongoing media access. By 2020, it hosted over 500 Rift-compatible titles, reflecting steady growth in VR software availability.[80][81] Key store functionalities supported user-friendly commerce, such as wishlists for tracking desired titles and receiving release notifications. A refund policy allowed returns for eligible digital purchases within 14 days if playtime was under two hours, promoting risk-free exploration. Family sharing was introduced post-2019, enabling up to three additional profiles on a single device to access purchased apps without repurchase. Additional features included user reviews for community feedback, VR-specific age ratings aligned with 13+ guidelines, and cross-buy options for select titles, granting access across Rift and Quest platforms with one purchase.[82][83][84][85][86]Integration and Post-Discontinuation Updates
The Oculus Rift demonstrated strong cross-platform compatibility early in its lifecycle, notably through integration with Valve's SteamVR platform. SteamVR support was enabled at the Rift's consumer launch in 2016, allowing users to access a broad library of non-Oculus PC VR applications directly via the Steam ecosystem without requiring the Oculus runtime for every title.[87] This interoperability expanded the device's utility, enabling seamless play of Steam-exclusive titles like Beat Saber and Half-Life: Alyx on Rift hardware.[88] In 2021, Meta introduced Air Link as a wireless solution for PC VR, permitting Quest headsets to stream high-fidelity experiences from a compatible gaming PC over Wi-Fi, which complemented the Rift's wired PC tethering by advancing the overall ecosystem's flexibility.[89] Although primarily designed for Quest devices, this feature underscored Meta's push toward hybrid wired-wireless PC VR workflows that indirectly benefited legacy Rift users through shared software advancements. Following Meta's corporate rebranding in late 2021, the Oculus ecosystem transitioned to the Meta Quest branding, with the mobile app officially renamed to Meta Quest on August 31, 2022.[90] The PC software, previously known as the Oculus app, was rebranded to the Meta Quest Link app in early 2024, maintaining backward compatibility for Rift headsets through version 50 and later, ensuring existing owners could continue accessing their libraries.[91] Oculus Link (later Meta Quest Link), introduced in beta in 2019, further bridged the gap by allowing Quest hardware to run Rift-compatible PC VR applications via a USB-C connection to a PC, effectively extending the lifespan of Rift software on newer devices.[92] After the Rift's discontinuation in 2021, Meta committed to ongoing software maintenance for legacy hardware, providing critical security patches and stability updates without introducing new features. As of July 2025, new installations of the Meta Quest Link app no longer support selecting the Rift CV1, though existing installations continue to function; Rift S remains fully supported. Support includes firmware and runtime updates via the PC Runtime (reaching v81.0 in October 2025), focusing on essential fixes like addressing intermittent tracking inconsistencies reported in Rift S units through targeted software tweaks, separate from the Quest-focused Horizon OS.[45][93][94][69] Legacy challenges emerged as certain titles faced delisting or end-of-support announcements, exemplified by Among Us VR, which ceased compatibility with Rift headsets on October 4, 2023, due to developer priorities shifting to standalone platforms.[95] Despite such removals, Meta preserved access to the core Oculus library for existing Rift owners via the PC app, emphasizing backward compatibility to honor prior purchases amid the ecosystem's evolution toward Meta Quest-focused development.[45]Technical Specifications
