I had almost no problems with the DK2, just had to swith the output adapter (VGA output).
However I am experiencing something like stuttering when moving my head, like if there was no low persistence enabled or something, hard to explain these things.
I had tried to use FPS limiter , but same results with 86 or 100fps limits.
I had seen this issue on more oculus demos, mostly on MyNeighbourTotoro however it was not that much noticable.
Anyways great to have such patch, you just made +1 user of your game
