By default, in OpenXR, an application will generate two images, one for each eye. One of those vendors-specific extensions is VARJO_quad_views, available on Varjo HMDs as the name of the extension indicates. OpenXR is composed of the core feature-set, multi-vendor extensions, and vendor-specific extensions. Future of Virtual Reality: The OpenXR Framework & Meta’s Prototypes This doubles the available PC render time and the effective encoder bitrate for PCVR-to-HMD streaming. Space Warp produces missing frames just-in-time on the HMD with no PC overhead, thus reducing PC-to-HMD bandwidth and stress on the encoder. Qualcomm added Space Warp functionality to their Adreno Motion Engine which runs on all headsets powered by the Snapdragon XR2 and its Qualcomm Adreno GPU. Last year, Qualcomm collaborated with Guy Godin, creator of Virtual Desktop, to enhance PCVR rendering performance. Switch this setup to a wireless HMD, and the communications channel (e.g., Wi-Fi, 5G, etc.) must also be up to the task of real-time data transfer. This setup must contend with fluid controller and game movements, 6DoF animations, head movements, and two render passes (one per eye) at 90 to 120 FPS. A typical PCVR (PC and VR) setup comprises a PC connected to a head-mounted device (HMD) and a pair of hand-held controllers that must all function in real-time. ![]() Rendering in VR demands that hardware and applications maintain very high frame rates. Unity Blog: Unity’s New XR Hands Package Adds Hand Tracking via OpenXR Spoiler: Support for FSR 2.1 is planned in future releases. With Je06jm‘s contribution, you can now also take advantage of AMD’s Fidelity FX Super Resolution 1.0 (FSR 1.0) to dynamically and beautifully render at lower resolution while keeping your game running smoothly. They’re also working on a Direct3D 12 renderer for better Windows and Xbox support. As always, Godot wants to see people create games on the full spectrum of devices for everyone to enjoy. For that, they’ve integrated an OpenGL-based compatibility renderer aimed at supporting older and lower-end devices. While Godot is excited to leverage Vulkan for performance optimization going forward, it was very important not to penalize users with less powerful hardware. With two new Vulkan backends (Clustered and Mobile), Godot rendering has never been so advanced. The Goldot team embedded OpenXR in the engine’s core and introduced Godot XR tools, which will help developers of XR projects. Godot 4.0 runs on Windows, Linux, and MacOS, and also Android devices. Unity Debut Meta Quest 3 OpenXR Development Package The deadline for receipt of proposals is 6:00 AM PT on Thursday, 3 August 2023. Companies considering making a bid in response to the RFP should notify the RFP list as soon as possible. Proposals, and any questions directly related to preparing a proposal, should be sent to the Khronos mailing list at. any interested organization or individual is welcome to respond. This RFP is being circulated to the public. The main goal of the project is to improve the general suitableness of Monado when used for XR display devices and companion devices as well as enhance various select key features that are considered important by Khronos. Monado is developed as an open-source project and is licensed under various permissive licenses explicitly listed here. One of the OpenXR runtimes that has risen in popularity these past few years is called Monado. ![]()
