Hi,
my card and CPU temps are in the limits. 4850 cards are a bit hot by default, but i've never ever had any problems in other applications - Crysis, GTA4 etc.
V-Sync is always turned off from the CCC /Catalyst Suite/. I haven't changed anything for some time, and as i said - i've played the game before without troubles, this was few months ago - the only thing changed since then, are the video drivers. I moved from 8.x to 9.1
@jackass888: Yes, i got a bit of lag, before this flickering starts - then i go to video options /menu is not affected/ and change anti-aliasing or postprocessing, video updates and game is fixed for few more minutes, then it starts again. I've tried to alt-tab yesterday, at first it was fixed, but on my second attempt i got BSOD with error in some ati***.dll file. May be is a good idea to roll back the drivers, and see if its drivers related or not.
Thank you for your time, guys, much appreciated!
