Good news everybody!
Valve has now fixed the issues in SteamVR that were causing performance issues and crashes in The Red Stare. The game should work correctly with motion smoothing as of SteamVR 1.3.19! Previously, the fix was only in the SteamVR Beta version from 1.3.2. This also increases stability for people with lower spec hardware.
From the patch notes: Fixed a memory leak in Motion Smoothing when the application’s resolution is rapidly changing.
