Did you extensively test every card? Or just check the main menu and leave because I personally can sometimes play a round or two and not have any glitches. It took me 3 or 4 rounds after installing the game to get any artifacts whatsoever. I downloaded the latest drivers (6.12) with the Catalyst Control Center, so it can't be an old Catalyst version. I installed the latest OpenAL too, so that can’t be it either. I fiddled around with the Geometry Instancing, Catalyst AI, and Vertical Refresh, all with no positive results. It’s safe to say that if it’s a specific system configuration, it’s a popular one considering how many people with a wide variety of ATI cards are having this trouble.
All I’d like to know is if Bohemia Interactive has been informed of this issue and that they are looking into it.
