After a good few days with my brand new Oculus Rift DK2, I have prepared a patch for the Caffeine Demo on Steam.
Non-Oculus Features
Implementation of Distance Field Ray-traced Shadows - Awesome penumbra, no shadow-map aliasing and better performance!
Large performance boost - R9 280 hits up to 80fps on max settings at 1080p (Level streaming still causing some jarring hiccups).
Menu system is in development - Very basic at the moment (does not render correctly in Oculus at this time).Oculus Features
Hotkey to switch between Oculus appropriate settings - Dynamic shadows are currently disabled for Rift settings as the DFRT Shadows have some strange issues in stereo at this time.
Hotkey to reset orientation / head position.Another patch will be released sometime in the next month with more performance and the inclusion of a shadow method that will work well in VR.
