NVidia Adaptive VSync is great in this situation.
Above 60 fps it enables vsync, effectively clamping your fps @ 60.
Below 60 fps (presumably a temporary situation) it disables vsync for performance...
Wish I had a 670!
Looking at a GTX 760 though, if availability improves in the near future.
Note: with traditional vsync enabled, it's a bad thing if your frames ever fall below 60 fps.
Instead of falling to 59 they'll fall to 30 fps...
Dunno if this is your situation or not - but I get no stutter at all (ever) using the NVidia adaptive.
Hmm,....thanks i try this out !!!!!
btw i have a GTX660 and i have some stutter at the cities for example Whiterun !!!
