Okay so I recently downloaded crysis 2, crysis 1, warhead and wars. Crysis 1 and 2 when I open them the main menus work fine until I do the campaign or multiplayer I have no hands, the gun is floating and I can see through the ground and walls but I can see some things in the distance. Not sure what the deal is. I have an XFX 7970 black edition so I don't think being able to play the game is an option. I also have already tried uninstalling and reinstalling and noting has changed, same results. Please help explain what I can do to fix this. I'm assuming I'm missing a download of somekind.

Thanks
