Motion Reprojection available for WMR headsets

[Ian Skippy]

WMR headsets cant use Steam's native reprojection solution, but there is a version for WMR available via the Windows Mixed Reality for Steam app.

Open the settings file:
C:\Program Files (x86)\SteamLibrary\steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings

"driver_Holographic_Experimental" : {
// Motion reprojection doubles framerate through motion vector extrapolation
// motionvector = force application to always run at half framerate with motion vector reprojection
// auto = automatically use motion reprojection when the application can not maintain native framerate
// "motionReprojectionMode" : "auto",


// Automatic motion reprojection indicator to display the mode currently selected
// 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
// "motionReprojectionIndicatorEnabled" : true,

Remove the first two dashes in red (next to "motionReprojectionMode" : "auto",) to enable motion reprojection. You can change it from auto if you want using the instruction above. If you want to be informed in-game of how it is behaving also remove the second set of red dashes. Now you'll get a little coloured cube in the top left of your HMD that shows you whether it is off because you are already performing great (green), it is on because either your CPU or GPU is bottlenecking (light or dark blue) or red because your performance is too poor for this to work.

What kind of effect is this having on performance?
