I am running Oblivion on vista ultimate and although it runs faster for some reason i cant set my 7900GT to run aa and HDR at the same time, resulting in that oblivion doesnt look as good...any help?
More aboutnvidia drivers 7900gt vista
The Geforce 7 series can not do Oblvion's method of HDR and FSAA at the same time. It's a hardware limit, not a driver limit. I dumped my 7800GT when I got Oblivion, as 1024x768 and no FSAA was horrible IMO.
