I first want to take the time to thank you, very much, for this post. I'm not sure how appreciated you can feel from some random guy's praise, but for the first time since I got this game I can run at better than 10 FPS. The previous guide never mentioned (or I missed) deleting the keys from LocalMachine and CurrentUser, so when I tried that fix it didn't work. But after reading this guide and seeing it's in two places, I deleted that and for the first time my run animation isn't done in 3 frames. Thank you, Thank you, Thank you Intel i-5 750 GTX560Ti 12Gb DDR10600 For anyone reading this, if you do step 2 and see Compatibility mode checked, you didn't delete the right keys, try again. If it's unchecked and the game runs like crap, I hope you get it fixed soon.
