Whenever I enable vsync in games I experience a minor but noticeable amount of mouse lag. It is bad enough to make me suck at all FPSs and gives me hell even in simple adventure games that involve a lot of point and clicking. Essentially it makes vsync unusable for me in all games. As can be seen from my GPU and monitor combo my FPS almost always stays above the refresh rate :lol: so the amount of tearing is comical.

My setup:
GTX260 - 180.43 BETA
E6750
4GB DDR2-800
Vista 64
1440x900 LCD (:sad

It seems both NVIDIA and ATI users have experienced this and solutions are few and far between.






Problematic games:

• *All* games
• Fallout 3, Oblivion, and Morrowind are the worst offenders
• Source games
• Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness
• Literally all games so I'll stop here :grin:

What didn't work:

• Forced triple buffering with D3DOverrider
• Tried all available refresh rates (60,61,75Hz)
• Various drivers
• Changed Prerender limit to 2 and 1
• Tried a PS2 mouse
• All combinations of the above and other snake oil tricks

What did work:

• Used to set max FPS slightly below refresh rate. For example if I use FPS Limiter to cap Fallout 3 at 55FPS and force vsync and triple buffering with D3DOverrider I get a responsive mouse with no tearing. Unfortunately FPS Limiter does not work with all games - stupid DRM issues.

So perhaps someone knows of a reliable fix? Setting a global FPS cap should do the trick I guess, but I don't know of a way to do such a thing.
