It might have some stability issues (I haven't seen anything posted about it with Wine in over a year now though), but if one can get it running, I don't think it would perform that bad.
It would depend on if you wanted it to work with the dx11 graphics or dx9 option. Dx9 is all consoles get so it wouldn't be horrible. The game is also nowhere as graphically impressive as some other PC games (Witcher 2, original Crysis, Deus Ex). Lots of low res textures in it that were not improved when porting from the consoles.
Don't get me wrong, I love the game, but it's a console port at heart and has the side-effects that come from porting it without improving graphically really. It wasn't a game I played for the graphics though and not something to nitpick really.
