Below you will find various Console commands that can be used to adjust the way Unreal Engine 4 (UE4) and SteamVR interact with one another.


Command	Description
vr.SteamVR.AdaptiveDebugGPUTime	Added to the the GPU frame timing, in ms, for testing.
vr.SteamVR.AdaptiveGPUTimeThreshold	Time, in ms, to aim for stabilizing the GPU frame time at.
vr.SteamVR.PixelDensityAdaptiveDebugCycle	If non-zero, the adaptive pixel density will cycle from max to min pixel density, and then jump to max.
vr.SteamVR.PixelDensityAdaptiveDebugOutput	If non-zero, the adaptive pixel density will print debugging info to the log.
vr.SteamVR.PixelDensityAdaptivePostProcess	If non-zero, when the adaptive density changes, we'll disable Temporal Anti-Aliasing (TAA) for a few frames to clear the buffers.
vr.SteamVR.PixelDensityMax	Maximum pixel density, as a float.
vr.SteamVR.PixelDensityMin	Minimum pixel density, as a float.
vr.SteamVR.ShowDebug	If non-zero, will draw debugging info to the canvas.
vr.SteamVR.UsePostPresentHandoff	Whether or not to use PostPresentHandoff. If true, more GPU time will be available, but this relies on no SceneCaptureComponent2D or WidgetComponents being active in the scene. Otherwise, it will break async re-projection.
vr.SteamVR.UseVisibleAreaMesh	If non-zero, SteamVR will use the visible area mesh in addition to the hidden area mesh optimization. This may be problematic on beta versions of platforms.
