psu brand and model?

Is this problem only in ac3 or in all games

 

[imrantheking]

try downgrading your gpu's drivers...That may solve your problem....

ac3 doesnt really work with crossfire/dual gpu cards, there's not much you can do about it except to disable the second gpu so it doesn't mess things up... (there should be an option for it in CCC or you could try running the game in windowed mode)

Assassins Creed 3 is a notoriously disgusting pc port, it's close to the likes of gta 4 pc version.
