Games created with 4.8.1 run at 37.5 fps when using the Oculus Rift DK2.
Steps to re-produce: create a new 4.8.1. project and use either VR Preview, or Launch and go into VR mode.
- Setting maxfps in console to 1000
- Disabling “hmd vsync”
- Disabling “r.vsync”
- Setting ‘Virtual Reality pre-rendered frames’, ‘Vsync’ and ‘Refresh Rate’ to ‘Use 3d Application Setting’ in NVidia Control Panel
The framerate outside VR mode is ~200 fps, far more than required even if it is halved for stereoscopy.
Environment: Windows 7 x64 (Aero Off); Core i7 3.4GHz; 32GB RAM; 4GB GTX 770
