FIXED: All the things!
TunnelVision achieved visual parity on nvidia and ati chipsets now!
It was quite the piece of work, but thanks to you guys and your detailed reports and help i managed to fix all the problems to run this game! (if not let me know!)

Now you can have this on NVIDIA cards! :D
Special thanks fly out to these guys for providing detailed info on the problems. Make sure you play their game aswell!
