r.CompileShadersForDevelopment Setting this to 0 allows to ship a game with more optimized shaders as some
editor and development features are not longer compiled into the shaders.
Note: This should be done when shipping but it's not done automatically yet (feature need to mature

r.DBuffer Enables DBuffer decal material blend modes.
DBuffer decals are rendered before the base pass, allowing them to affect static lighting and skylighting correctly.

Deferring updates is more efficient because multiple SetVectorParameterValue and SetScalarParameterValue calls in a frame will only result in one update.

Slate.PreventDuplicateMouseEventsForTouchForWindows7 Hack to get around multiple mouse events being triggered for touch events on Windows 7 and lower. Enabling this will prevent pen tablets from working on windows 7 since until we switch to the windows 8 sdk (and can use WM_POINTER* events) we cannot detect the difference
Slate.RequireFocusForGamepadInput Whether gamepad input should be ignored by the engine if the application is not currently active

Numbers larger than 2 may be possible and specify HMD plugin-specific variations.
Negative values are treated the same as 0.
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 reprojection.
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.

Set this to a non-zero value to disable this behavior (not supported on all platforms.)
