Ok I have been doing some testing and here is what happens. Playing the game with 1024x768 @100hz with vsync on. These settings lock the framerate at 100FPS. Using fraps and the ingame counter, (ctrl+F8) During certain times in the game the frame rate reads exactly 100 FPS and no fluctuating. as long as it stays right at 100 it is ""perfectly"" smooth. But the second it drops to anything but 100 even if it just drops to 99FPS or 98 FPS sometimes 95FPS or so = instant stutter, lag, frame rate stutter. It honestly looks like it's at about 5 or 10 FPS but it reads in the 90's. Then when it goes back up to exactly 100FPS, (where the refresh rate and vsync is) it instantly becomes smooth again.
When it dips to 98 or 95 or so the frame rate looks really low. I can see the slowness to the framerate. I shouldn't be able to see a huge difference between 98FPS and 100FPS what is going on here?
