So, klll the anti aliasing and the enb? I'll try that and see if it helps, thanks, guys. What is ati aliasing anyway?
Anti-aliasing smooths out edges and makes things look less jaggy/have fewer jagged edges.
Also, it's worth pointing out that if you are indeed having gray pixel squares like the ones shown in povu's picture, turning off AA is a bandaid fix. This was a problem that cropped up in the 12.2 AMD drivers, and the only reason for it to persist into later driver iterations (12.3, 12.4) is because you installed a newer driver set over the faulty 12.2 set.
To truly get rid of them and fix the issue (and keep your anti-aliasing), you need to completely uninstall your current GPU drivers and reinstall with a fresh set. Any driver version other than 12.2 will do; current version is 12.4, although some people have reported issues with it. 12.3 or 12.1 should also work fine.
If you don't know how to do a clean upgrade like that, follow the instructions http://www.gamesas.com/topic/1368527-graphic-issue-pixelated-like-image/page__p__20665695#entry20665695.
