graphics bugs with ATI 4800 series (4850/4870/4890) in ARMA 2 & OA - TROUBLESHOOTING Posted August 4, 2009 you do not need to set it catalyst A.I. to advanced. but if you rename, you will still have to use the "-winxp" flag. No strobe with the 9.7 and arma2.exe, but you still get some sever light changes. Crysis strobes, but is not as extreme light to dark. Almost there Bis and ATi... Vsysnc is locked in Vista64 and Rc7, some have had ? success with Ray's Ati tray tool. Some missions seem to have a cap....some are total pigs. I'm wrote this because in 9.7 driver you have AFR profile for ArmA 2.
