I have a very similar problem.
I can chose the 3D-Hardware, but when the mission-loading-screen appears, the game tells me, that it wasn`t successfull in detecting my 3D - hardware.
This is VERY annoying, since it worked before my system new installation.
I`v got a ATI Radeon HD 5570 card.
Please help me somebody! The hints above don`t work with my system...
