You probably can't. Diamond has gone through so many mergers that is is almost impossible to find recent drivers for any legacy product. I'm still looking for a XP Driver for my Diamond Stealth S450 Xtreme.....
There is also a "supplemental driver for use with Unreal Tournament only" on the same page (at the bottom of the page).
This is a MeTaL driver and allows for the use of S3TC texture compression in Unreal Tournament.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
