After much testing I have found that they have changed something with the fps limiter in this new patch. If you see black/grey artifacts on the right side of your screen, you must cap your frame rate to 60fps or less if you're using 60hz. Type in Console sys_maxfps 60 or make an autoexec.cfg with that in it. I have no idea if you can go higher with other displays or not, but this is the solution to the problem that many ppl have reported since the patch. Hopefully Crytek can explain why this is happening to Nvidia users?
