Hey there,
First of all, thank you daeiron for taking your time trying to fix a game.
However none of these ideas have helped me. I'm using an HD 5750, 4gb ram, intel core i7 3.2ghz, which I know, isn't that good anymore. And I'm not expecting to get crysis 2-like graphics with everything on ultra... even though crysis does run with everything on high and 2 other things on ultra.
I have tried everything I've come across so far, reinstalled the game 4times, I've tried both 11.9 rage drivers, the 11.10 battlefield 3 beta driver, the clean 11.9 driver and some random lower driver, someone somewhere said could work. I went through every option, I enabled / disabled everything to see what works best I even reinstalled windows :/ and right now I'm using the solution you offered.
Your solution is showing by far the best results in terms of how smooth and nice the game runs. It's pretty much perfect with next to no crashes, if it wasn't for the artifacts, which are literally unbearable, random clippings, enemy skins flicker sometimes, etc. Once I create the .cfg file everything is checkered all of a sudden and I have no idea why. Without the .cfg file The framerate drops a little, I have less artifact problems and I get crashes everytime I go from somewhere very light to somewhere very dark.
I mean, ugh... I'm really tired... I don't mean to sound angry or something, and I don't want people to go all crazy about this... it's just so disappointing :/ I've been trying to fix this for the past 5hours. I just don't know what to do anymore. I realize I'm not that tech savy but I know I can follow instructions and most of the times I can fix stuff on the computer, following instructions. I somehow feel like it's my fault, too. I don't know. I like Bethesda I really do but geez... 60$ is a lot of money. I'm dissapointed, mostly in myself because others seem to be able to fix it quite well. And now this post has turned into me rambling because I can't go to anyone else with that

.
Either way, I'll just return the game and skip this one, hoping I don't miss out on too much.
