What I did:
-Changed dx9 to dx10 in system.ltx
-Turned off Catalyst A.I.
-Used Application Settings on all steps in CCC
-Enabled Triple Puffering for OpenGL
Worked for me without FPS drop.
-Motherboard: Gigabyte 8IPE775
-VGA: Gigabyte HD465...
Upon launching the game everything works fine. When i start the singleplayer, i can't see any characters, i can see only floating guns. I have 50fps while playing. I looked at the discussions and couldn't find anything like this. Help please.
