Windows Mixed Reality for SteamVR Beta Updated

Windows Mixed Reality for SteamVR has been updated to version 1.1.192. This build contains the following changes:
  • Resolved an issue where controller haptics might not activate.
  • Resolved a crash that might occur on some Nvidia driver versions.
  • Reduced a source of blurriness for titles that use dynamic resolution, such as Half-Life: Alyx and the SteamVR Home.
  • Added a new dynamic resolution indicator: shows the maximum requested application size (gray) and the size of the current frame (blue).

Windows Mixed Reality for SteamVR Updated

Windows Mixed Reality for SteamVR has been updated to version 1.1.186. This build contains the following changes:
  • Added a list of titles that should respect the SteamVR motion smoothing setting to control motion reprojection in order to ensure a stable playing experience.
  • Fixed an issue with skeletal input not being available for custom input bindings.
  • Updated the motion reprojection indicator to always show when enabled, regardless of current reprojection mode. Previously, the indicator only showed when reprojection mode was set to auto.

Windows Mixed Reality for SteamVR Beta Updated

Windows Mixed Reality for SteamVR has been updated to version 1.1.186. This build contains the following changes:
  • Fixed an issue with skeletal input not being available for custom input bindings.
  • Added a whitelist to allow specific titles to always respect the SteamVR motion smoothing settings, regardless of what motion reprojection mode is specified in default.vrsettings.
  • Updated the motion reprojection indicator to always show when enabled, regardless of current reprojection mode (previously, the indicator only showed when reprojection mode was set to auto).
  • Updated default.vrsettings to explicitly set the motion reprojection mode to disabled by default.
  • Updated how the motion reprojection setting is handled (see below).


[h2]Motion Reprojection Setting Changes[/h2]
This beta makes changes to how motion reprojection settings can be managed. Like before, the default.vrsettings file can be modified to specify the reprojection mode to use for all titles. As a reminder, the possible values are:
  • disabled - motion reprojection is never applied.
  • auto - motion reprojection is applied if the running title cannot maintain native framerate.
  • motionvector - motion reprojection is always applied.


Alternatively, if you're using Windows Mixed Reality for SteamVR in conjunction with the latest SteamVR release, you can now use SteamVR to manage motion reprojection settings on a per-application basis. To enable this functionality:
  1. Ensure you're running a supported version of SteamVR (1.10.28 or greater).
  2. Remove the "motionReprojectionMode" line from default.vrsettings.
  3. In the SteamVR settings, select Video > Per Application Video Settings.
  4. Select the title you're interested in, and change the motion smoothing option.
Motion Smoothing Setting
  • Use Global Setting - no application specific override. The global default mode is auto.
  • Enabled - motion reprojection runs in auto mode, applying reprojection if the application cannot maintain native framerate.
  • Disabled - motion reprojection is never applied for the application.
  • Force Always-on - application runs at half-framerate with reprojection.


[h3]Locating default.vrsettings[/h3]
There are potentially multiple default.vrsettings files on your system, and it can be tricky to know which one to modify to enable the above behavior. The file that needs to be changed is part of the Windows Mixed Reality for SteamVR installation. On systems where you haven't modified your steam library path, it can be found at: C:\\Program Files (x86)\\Steam\\steamapps\\common\\MixedRealityVRDriver\\resources\\settings\\default.vrsettings.

On systems where you've installed Windows Mixed Reality for SteamVR to a different path, you can locate the file by doing the following:
  1. Locate Windows Mixed Reality for SteamVR in your Steam library, right-click it and select Properties...
  2. In the properties window, select the LOCAL FILES tab, and click the BROWSE LOCAL FILES... button.
  3. In the file explorer window that opens, you can locate default.vrsettings under the resources\\settings folder.


Updated on 3/17/2020 to add instructions for locating default.vrsettings
