I have a 6970 2gb gpu, so I should be able. Im putting
vt_pageimagesizeuniquediffuseonly2 8192
vt_pageimagesizeuniquediffuseonly 8192
vt_pageimagesizeunique 8192
vt_pageimagesizevmtr 8192
vt_restart
vt_maxaniso 4
image_anisotropy 4

into rageconfig.cfg in base folder... but nothing, nothing is happening... remains the same blurry textures. Can anyone help, what am I doing wrong?

Try deleting the "vt_restart" and see..

your not doing anything wrong there is minimal difference. and you dont need to do a config anymore just patch and set texture cache to high.

Didn't do anything... I wish ID would release a patch so we could through the game set this ourselves...

I think there is a bit of different.. noted here http://www.geforce.com/Active/en_US/shared/images/articles/ragetexturetweak/RageComparison-Animated.gif
