Hi everybody! I plan to install Windows 7 within a week on my PC. I play games such as Crysis, Mirror's Edge, Call Of Duty Modern Warfare, etc. Will the games by default use DX10 after installation? Do I have to select any special modes? Also, I know that Win 7 comes with DX11. Do I need to install DX10 or DX9 on it? Really stupid questions I guess. Awaiting your responses. Thanks.
