Please fill in your specs

:ar: System Specs Tool

I would suggest that you make sure you have the latest video drivers

Androi, what games does this happen in?

Edit
I did some reading of other people having this problem and it was driver related. Try rolling back to an older driver and see if it goes away.

games: state of decay, outlast, medal of honor and need for speed most wanted
i removed the new driver and i installed the old driver from CD.. but this didn't resolve the problem
