Re: NVIDIA Responds to Reports of Kepler V-Sync Stuttering Issue
I have noticed the stuttering on my MSI 670 in iRacing with vsync enabled, but to tell the truth it isn't that big of a deal to me. It appears to be driver related, so a fix is coming.
I use vsync in in FPS's because I am one who hates tearing. But in iRacing there is no tearing with vsync off, so no need for it. I just limit the FPS in game as suggested by SlaWter.
