I'm getting anywhere from 10fps to 60 on my HD5770. Is there a known bug in the game that makes your frames jump as soon as you take a look over the horizon? Right now I'm playing at the lowest possible setting at 1920x1080. Even if I lower my resolution, I still get weird lag that makes the gaming experience feel like playing inside a pool filled with honey.
I should be able to max this game with good frame rates. Does anyone else get this with their HD5770? The game looks pretty bad at the lowest setting, but I get constant 60fps.
