Majority of the time fallout 3 runs pretty smooth(60fps), but when i arrive at point lookout pier, at points it'll crawl down to 30 fps, wtf? i spent $350(about $1400 on the whole system) on this card recently & can't even run a 4 year old game on max? -__- is this card just s***? or theres something wrong with my system?
More about :fallout max graphic settings asus gtx 670 dcu lagging wtf
Fallout 3 is a buggy masterpiece, and that has been known for a long while. Last time I went through I had to rush through the vault escape sequence as it would always crash in this particular room, so as soon as I got in there I sprinted to the other side and out of the vault.
Chances are its just the game, your hardware is fine.
