Mouse is lagging

My mouse starts lagging everytime I load up Warcraft III:TFT. I updated my drivers after I reformated. Both my mouse and my video card drivers. It didn’t do this before the reformat and I’m curious if anyone has any knowledge or any inclination what the problem could be.

I don’t play Warcraft but I have had issues with some games where vsync is on. If it is on, try unsetting it to see if that makes a difference. If not, I’m out of ideas already!
