Windows Mixed Reality für SteamVR

SolKutTeR · 1. April 2018

Umfangreiches Update für die Beta Branch.

Motion reprojection available as experimental option for Beta users
With the latest public beta (0.1.1001+), we've added an experimental option to make 90 FPS reprojection smoother when running SteamVR with Windows Mixed Reality.

If you choose to enable motion reprojection, all Steam VR games will render nominally at ½ frame rate (45 FPS instead of 90 FPS) while Windows Mixed Reality for SteamVR uses motion vectors generated by the GPU to extrapolate the next frame. For SteamVR games that reliably hit 60 FPS+ on a given PC, this should result in a solid 90 FPS experience with occasional artifacts while maintaining a comfortable experience.

Initially we have experimental support for recent generation NVidia GPUs. We are continuing to iterate on and improve our motion reprojection support on additional GPUs, and we’re eager to hear your feedback.

If you're not a Beta user, this optional feature will be available to you soon the next time we release a build to the main branch.

Thank you to everyone who gave us feedback to make better reprojection a priority. We are listening and adjusting our plans based on what we hear from you here in the forums and on Reddit. Thanks again, and please keep the feedback coming!

Instructions to enable
You can opt-in to this mode by updating the MixedRealityVRDriver\resources\settings\default.vrsettings file in the MixedRealityVRDriver install folder.

Make sure you have opted into the Windows Mixed Reality for SteamVR Beta using the instructions on the enthusiasts guide.

Close SteamVR if it is running

Edit "C:\Program Files (x86)\Steam\steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings" (Path will be different if Windows Mixed Reality for SteamVR was installed to a different library)

Add this line just below "driver_Holographic_Experimental" as shown in the example below "forceHalfRateWithReprojectionMode" : "motionvector",

Restart SteamVR with Windows Mixed Reality

Expected Visual Artifacts

Sharp contrast edges or text, especially on in-game HUDs or menus, may look temporarily warped or distorted due to disocclusion

Games that do not reliably hit 50-60 FPS on your PC will continue to have a poor experience with this mode

@SolKutTeR Verstehe ich aber richtig, dass das nur funktioniert wenn ich in Steam unter WMR Optionen auf "Beta" umstelle oder ist allgemein die WMR App noch Beta-Stand ?

SolKutTeR · 20. April 2018

@Oege
So habe ich es auch verstanden, dass es lediglich die WMR Option bezüglich der Beta ist.

Neue Settings mit der neuen Beta v0.1.1093.

Automatic Motion reprojection setting for Beta users
As part of the public beta update to version 0.1.1093, we've added an automatic motion reprojection mode.

When motionReprojectionMode is set to "auto", motion reprojection will turn on automatically when a game is rendering too slowly to maintain 90 FPS. When a game begins to maintain 90 FPS or starts rendering at less than 45 FPS, motion reprojection will turn off.

Some beta users have reported compatibility issues with specific games. Please continue giving us feedback and we will reach out to the game developers to fix these issues.

Neuerungen der nonBeta Version.

Windows Mixed Reality for SteamVR Updated version 0.1.1034

Fixed a rare crash while exiting

Reduced the likelihood that a game will use the wrong controller for a particular hand

Fixed a bug where SteamVR would believe a controller was still connected even after it was powered off. This sometimes led to the controller hanging in space instead of disappearing after turning it off.

Neues Beta Update und verlassen des Early Access Status.

Windows Mixed Reality for SteamVR Beta Updated
The public beta has been updated to version 0.1.1123. This update includes the following changes:

Fixed a bug with the thumbstick control experimental feature when combined with motion reprojection

Fixed a bug which could cause severe artifacts when motion reprojection toggled between on and off

Added logging to help diagnose issues in motion reprojection

Added experimental option “motionReprojectionIndicatorEnabled” that, when on, will display an indicator when the experimental automatic motion reprojection is enabled. Details below.

Updated the EULA now that Windows Mixed Reality for SteamVR has exited early access

motionReprojectionIndicatorEnabled is a new setting in the configuration file to help diagnose issues with the experimental automatic motion reprojection feature. When set to true, you will see an indicator in the headset that corresponds to the current motion reprojection mode:

green = off because application can render at full framerate

light blue = on because application is cpu bound

dark blue = on because application is gpu bound

red = off because application running at less than half framerate

See enabling motion reprojection for SteamVR apps[docs.microsoft.com] for more details.

Windows Mixed Reality for SteamVR Exits Early Access
With today’s release of the Windows 10 April 2018 update[blogs.windows.com], we are pleased to announce that Windows Mixed Reality for Steam®VR is coming out of “early access”!

This announcement recognizes the continued improvements over the last five months coupled with the new fixes and features in the Windows 10 April 2018 update that released today. Since we first made SteamVR available to all users in November, we have released 10 updates to all users and 24 to Beta users. Those updates have resulted in significantly improved performance and stability, added haptic feedback for motion controllers, and improved how motion controllers appear in SteamVR. On top of that, 422 games in the Steam Store now officially declare support for Windows Mixed Reality.

We wanted to take this opportunity to say a huge THANK YOU to the members of our community who have given us great feedback to help make SteamVR a better experience for Windows Mixed Reality. It’s important to clarify that today’s announcement doesn’t change anything about our ongoing commitment to our SteamVR experience and our community. We will continue to release regular updates with new fixes and features, and you will still find us here in the discussion forums. We aren’t going anywhere. In particular, we’ve heard the community’s requests for more customizable input and the ability to launch from the Cliff House. We’re investigating solutions and look forward to sharing more details soon!

Habe soeben Spring Update (1803) und das neue WMR for SteamVR installiert. Laut Berichten auf Reddit soll das Controllertracking deutlich besser sein (wobei ich vorher auch keine großen Probleme damit hatte) und SteamVR-Anwendungen sollen performanter laufen, da weniger VRAM durch WMR verbraucht wird. Werde heute abend mal testen.
