Well a fresh install fixed it...not sure what caused the problem. I do notice now that if I turn on vsync, it causes bad judder as one would expect, but then when you turn it back off, it doesn't fix the judder. I have to restart the game with vsync off to fix it.

Other than that, this patch is amazing! Positional tracking works amazingly well, and chromatic aberration doesn't seem to be a big problem. Keep up the good work, Scawen!

After the latest test patch adding CAC, I'm getting really bad judder, which I wasn't getting before. I've tried turning vsync off, and back on, and I tried cycling back to a monitor then back to the rift, and I tried re-patching. Only thing I haven't tried is re-installing from scratch, which will be my next option. Any ideas?
