I've got a simple textured cube that I'm rotating on-screen and with vsync enabled it looks choppy as it animates, but if I disable vsync it's absolutely and perfectly smooth. This seems backwards of what I would expect to be the case. I understand that vsync will lock for monitor refreshing, but this shouldn't manifest in visual choppiness. I've got two nVidia GTX 460s with SLI and zero GCing happening.
Any suggestions?
IIRC Vsync only works properly in fullscreen but could be wrong.
Thanks, I'll give that a try and see if that makes a difference.
Vsync works fine for me in windowed mode...
Are you using windows XP? If so, do you have a Thread.sleep() in your render loop? Longer delays between successive sleep calls could actually make the amount of time it sleeps for rather inaccurate.
This could also be driver-related - I'd update to the latest just in case it solves your headache, before spending too much time trying to debug it.
