Problems with ATI Radeon HD 5750 on Late-2010 27" iMac in BootCamp (Windows 7 64-bit)

Hi, Guys.

My Radeon HD 5750 is giving me some troubles while playing games. It randomly dims and I take a big frame-rate hit. I've tried searching the Internet and the forum for any similar issues but I can't find anything related to this...The display itself doesn't dim. Just the image on the screen.

This happens in a few different games of varying age and engine so I'm not sure what it could be. It also does not happen at all when in OS X (same games where applicable) nor when I'm just on the Windows Desktop doing Windowsy things.

I'm on a Late-2011 iMac 27", 4GB, Quad-Core i5 @2.8GHz.

Thanks!
