I kind of found an answer to part of this issue on another post, I know as of now Nvidia cards don't support directx 11, even though my system is running it. The GTX 260 says it supports dx9 and dx10, I just upgraded to Windows 7 64-bit and I'm wondering what dx version is the card actually running on, dx9 or dx10? I had dx9 before with XP. If it is still running with dx9 is there a way I can get it running to dx10, or does that only work with Vista? Obviously because the card doesn't support dx11. Basically, is my card stuck running on dx9? Thanks in advance. 😀
