Patch 0.2.90.0

Updates

 * Game goes to unplayable framerate upon going underground. Seems an issue with computing reverb on certain hardware. We've disabled reverb for now and will investigate later.
 * Fix for 100% crash for users with Intel Core2 Duo and Core2 Quad processors.
 * Fix for SteamVR launching alongside the game. We don't have VR support!
