So, after getting my 6850 i was expecting things to run great, which they do mosatly. I can max out crysis warhead and get smooth gameplay. Fallout 3 is another story. The fps dips down to 30fps or lower. Turning on/off vsync doesnt affect performance at all, still capped to 60fps. Turning down detail settings doesn't remove this anomoly. Is a 3.2ghz core 2 duo really not enough to run this game at a constant 40fps+? thats what i would like to achieve. The times the FPS dips is really random, like being in an open field looking to the distance its 60fps solid mostly, then duck between some buildings and look at a wall and its 30 fps..... i cant figure this one out. I'll probably look at the fallout 3 tweak guide and try some things in that. And yes i have latest catalyst drivers and all win 7 updates and the game is legit and updated. Would like some input from someone else running the a 6850 and what settings and FPS they are getting.....
