Nvidia’s new Kepler-based graphics cards are still fairly new on the scene, but a fairly serious new bug has emerged that started out as a forum rant , and has evolved into an official acknowledgement from the green team. The problem in question seems to be limited to GTX 670, 680, & 690 customers who enable v-sync though the Nvidia control panel, and by most accounts, is pretty infuriating.
Multiple news outlets have requested a comment from NVidia on the issue, however a response to the forum thread has finally brought closure to the issue, which by the sound of it, will be resolved in next month’s drive release.
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.
