Got to play for almost 2 hours. With the render fix the game looks great and runs smooth. I went out and bought a 360 controller, I tried to play with the kb/m but it is horrible controls for this game imo. I may be biased as I played the game when it first came out a lot on my PS3. The only issue with using the render fix is the messages left on the ground don't show up. The guy who made the mod is going to work on that issue tomorrow and hopefully can fix it, if not though, it isn't a big loss and well worth the trade for the higher resolution.
EDIT:
Forgot to mention, good old GFWL struck again. The game was crashing when I tried to launch it, ended up having to uninstall all GFWL crap and reinstall it and then the game launches fine, sigh, I swear MS is trying to piss people off.
