MOuse lag in games

I just started getting mouse lags yesterday for no apparent reason.

I took a break from gaming for about 2 weeks and when i went back to playing dead space3 i noticed the lag. It also happens with bioshock infinite and every other game. 

I have a steelseries wow cataclysm mouse. I have kinda big hands and it has great ergonomics.

I use a 1080p screen and 3200 cpi if that matters.

Please can someone help me fix this lag. I tried everything.

Sounds like it might be a tracking problem if it happens with everything. Have you tried it on different surfaces?

Did vsync get turned on?  check you GPU control panel maybe it is being forced.
