Its been like this with my computer for quite some time now, and all of the tips that have suggested do not work as there is no updates for my graphics card (ATI radeon 3000 piece-of-shit-series.)

I even reinstalled the WIn7 and all the graphics drivers etc and its still like this.

Its really annoying on maps like Dreadful place, where enemies blend in to the background...What to do?

Buying a new comp is not an option.
