I have not tested DX8 yet, but could not find a claim on Nvidia's WEB site that the 6.50 drivers are DX8 certified. They do mention DX7.
Due to the inability to switch between DX7 and DX8 without a complete re-install of the OS, I have had the tendency to wait until I see the video card guys claim support for the version of DX.
DX8 opens a can of worms with its changes. Unlike switching from DX6 to DX7, there can be compatibility issues with DX8.
I know a lot of people that would say it is fine with the GF drivers,...but for me,..its not worth the risk. If the video card guys are not willing to claim thier drivers are DX8 compatible, then I have to beleive there is a reason.
Of course,..I might not have found the right place on NVidia's WEB site.
I also have concerns with older games I play, so it might be a while before I upgrade to DX8. From what I can tell,...it appears MS was concerned about W2K and ME support, and that pushed DX8 out the door. Maybe I am being paranoid, but until I can fully test DX8 on a system I don't care about, I cannot afford to take the plunge.
