Tom's Hardware reports some users of NVIDIA's high-end GeForce GTX 600 series graphics cards suffer from a V-sync stuttering issue. The site wasn't able to reproduce the issue and assumes it does not apply to every configuration. They contacted NVIDIA and got to hear that the issue will be fixed on the next major GeForce driver release in June.
Eager for an explanation, Tom's Hardware reached out to Nvidia for its response, understanding that owners of $400, $500, and $1000 graphics cards want to know why their boards are misbehaving. The company sent over an official response to the GeForce GTX 600-series stuttering issue, which reads:
We have received reports of an intermittent v-sync stuttering issue from some of our customers. We’ve root caused the issue to a driver bug and identified a fix for it. The fix requires extensive testing though, and will not be available until our next major driver release targeted for June (post-R300). For users experiencing this issue, the interim workaround is to disable v-sync via the Nvidia Control Panel or in-game graphics settings menu.
