I'm using a ATI HD6850 with newest 13.1 catalyst drivers, i5 2510 and win7@32bit.
When i start a new game, entering a new map, my FPS drops significantly. When the combat begins, it drops even more. My FPS likes to blink between a very low value and 60. The actual FPS is like below 5. After about 10-15 secs, everything goes well. And it drops again when entering a new map. I've tried to turn down the quality but nothing changes.
Can some one help me out?
