This sounds very strange so I would like to get more information about your system. Can you please kindly provide your dxdiag report, system information and graphics report?
How to get it?
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach using Advanced Editor Options.
System Information: Click Start> Type System Information> Click File> Export> Save File> Attach using Advanced Editor Options.
Graphics Report: Right click on desktop> Graphics Properties> Options> Drop Down Menu> Information Center> Save> Attach using Advanced Editor Options.
Also, can you let me know what game are you playing and if it has the latest patch? Before updating the driver was it working fine?
As last question, do you remember what driver version was installed before?
I appreciate all information you can provide.
