In this segment of the video, the speaker introduces the OpenXR toolkit and Open Composite to enhance VR experiences. The OpenXR toolkit, created by developers independently of Microsoft, offers features like upscaling, sharpening, foveated rendering, and eye tracking to optimize performance for games supporting OpenXR. Foveated rendering uses variable resolution to lighten the GPU workload. Additionally, the OpenXR toolkit includes upscalers like Fidelity FSR and Nvidia’s NIS. Open Composite is discussed as a means to make SteamVR games compatible with OpenXR. These tools aim to improve VR performance and visuals on various headsets.

In this segment of the video, the speaker discusses how SteamVR uses its own API called OpenVR, which can present issues when trying to play games like Dirt Rally on devices that do not natively support OpenVR. They introduce Open Composite as a solution that acts as a translator, allowing OpenVR protocol games to be run as OpenXR applications. By using Open Composite, users can access and play OpenVR games with the OpenXR runtime without going through Steam or Windows Mixed Reality (WMR) platforms. The speaker also provides steps on how to set up Open Composite and Open XR toolkit to enable compatibility with various games. They highlight Microsoft Flight Simulator 2020 and iRacing as games that work with OpenXR out of the box, emphasizing the importance of using Open Composite to expand the range of compatible games with the OpenXR toolkit.
00:06:00
In this part of the video, the speaker demonstrates how to install the OpenXR toolkit and Open Composite. They show how to switch between Open Composite and SteamVR using a simple button in Open Composite, which eliminates the need for manual copying of Open Composite dlls. The speaker also explains how to use the OpenXR toolkit companion app to adjust settings and navigate the menu using hotkeys. They mention enabling the FPS counter and performance options in the OpenXR toolkit menu. The video concludes with launching a game in SteamVR mode and adjusting performance settings like scaling options and image sharpening.

In this segment of the video, the key points discussed include:
– Explaining the importance of disabling in-game upscalers like FSR or DLSS if you plan to use a different upscaler.
– Instructions on adjusting the Nvidia image scaler (NIS) and the need to restart the VR session for changes to take effect.
– How to adjust the scaling option to render applications at a percentage of the headset resolution, with values below 100 or above 100 explained.
– Mention of the fixed foveated rendering for performance enhancement, with quality and performance mode options.
– Introduction of the turbo mode for performance boost, cautioning that it may cause game crashes.
– Discussion on train throttling and statistics options for further adjustments and monitoring the frame time.

In this segment of the video, the narrator discusses adjustments that can be made to the image seen in the headset, such as contrast, brightness, exposure, and shaking reduction settings. There is also mention of overriding display resolution and changing font size and opacity. The main focus is on fixed foveated rendering and upscaling for optimal performance. Different settings are shown using an openxr toolkit with Quest 2, highlighting performance variances in GPU time.

In this segment of the video, the speaker discusses the performance of different VR settings on the HP Reverb G2 headset. They mention being CPU-bound and needing to hit 11.1 milliseconds on GPU time to achieve a consistent 90 FPS. Various configurations are tested, including default, performance mode with foveated rendering, and a custom Epic preset with reduced VR pixel density. The adjustments successfully reduce CPU load and maintain a steady 90 FPS. The speaker also evaluates performance on Auto and blister 2 in The Nightmare Night and Rain mode, observing improvements in FPS with specific settings adjustments, including balanced mode and NIS scalar. These optimizations enable smoother gameplay experiences, particularly for those running VR on lower-end GPUs.
