TNT2, or TNT not haveing 3Dnow! drivers/support?...better research again.
I have Just a regular TNT, and yes TNT, and I'm sure that TNT2 will have them as well, but who knows unil the card is out, have the 3Dnow! support/driver/patch. I just downloaded it last night.
Go to www.diamondmm.com and you will see.
Steve, there would be a bigger commotion if the 3DNow drivers were actually out. The 3DNow was probably mentioned in relation to DirectX or some other sleazy idea, there is no benefit between the 0.48-based drivers and Detonator drivers for OpenGL games.
What you are after are the Predator drivers which should be out in a few weeks time. AMD and nVidia have both been working on these to get good 3DNow optimisations out, so keep an eye out for performance figures on those.
Just to recap, if there are ANY 3DNow instructions in the current TNT drivers then there are only 1 or 2, there is no performance change at any rate.
