thanks for the reply but i doubt it's on of the obove things:
- sideband addressing is not giving such a performance boost as well as 8x agp is not. this should be only noticable with huge(!) amounts of data like big textures even cutting edge games rarely use
- other compareable machines are running x with the same color-depth
it's not like i think, "mhh this card could like a little tweaking", for me it looks like a serious misconfiguration of my hw/sw.
even my 'old' ti4200 performs as it should. probably i just have a broken card..
on the other hand, i deleted wintendo some weeks ago, but iirc the card performed as it should unter ms's system. i just don't want to reinstall this os to verify
