Weird performance issue with OpenGL + Direct mode
I have an NVidia GTX 770 running driver version 344.48, and I can't get any kind of decent performance using OpenGL. If I set "Vertical sync" to "On" in the Global Settings section of the NVidia control panel, only 1 in 3 frames renders in 13ms (75fps), and the other 2 of 3 render in 26ms (37.5fps).
If I set it to any other value, even "Use the application setting", then each frame takes 3 seconds to render (0.33fps!)
What am I doing wrong? This seems like a HUGE regression from 0.4.2. Extended mode seems to work fine except for the frame rate dropping every few seconds. The odd thing is, it works perfectly on Linux, which is surprising considering how little emphasis Oculus seems to place on Linux support.
Here is the program I am using (source included): https://www.jspenguin.org/software/glbumper/files/simplevr-0.1.zip

- Hi jspenguin
I'm having a similar issue with OpenGL currently. Did you find any solution for this problem or did you have to revert to 0.4.2? - I was not able to find a solution other than just using extended mode. I did not want to downgrade, because then I would lose Linux support.
