I have two brand new HD4890's (crossfire'd) and am equally shagrined to find that I have the same CTD problem with IL-2 that others report. I'm using Win 7 RC, so I thought it was with windows or an overclock problem. But, apparently not so. It seems whenever I play online in a COOP with my squadies, I CTD within 10-15 mins of game time. I've tried Catalyst 9.8 and 9.9 drivers and have experienced the problem with regularity when using OpenGL. Doesn't matter whether it's 'perfect mode' in graphics or not. OpenGL use in IL-2 = CTDs. Oddly, I can't replicate the problem as easily with offline play, but have seen it happen. I also noted the ati0glxx.dll issue in the event log and loaded an internet found-copy (2004 version) of that file in the windows/system32 folder, but it did not fix the problem. I understand from other forums that this is thought to be a memory leak with the current drivers and earlier versions might work OK with IL-2. I've backed-out to Catalyst version 9.6, but haven't tested it just yet. I logged my situation at the ATI tech forums and recommend others do the same. Suggest others do the same. I'm kind'a forced into using this card(s) until DX11 cards come out. If ATI doesn't give me satisfaction in the next 30 days with a fix, I'll pull the plug on ATI and when the DX11 cards for NVidia come out. I'm a patient person, but this problem should have been fixed by now as it's been known since late July, so this is completely unsatisfactory to me. As a series IL-2 is quite old now, but as a game it is still the premier online combat sim. What's ATI's problem. Have they just given up on this sim to NVidia?
