View Full Version : GF4 FSAA and Alpha Textures on Older games

08-Feb-2002, 13:55

We all know that with MS we lose the ability to do any AA on this Alpha textures. However the K2 drivers had a swich to allow "proper" handling of these. And newer games are using Alpha blends to avoid this issues (AVP2, RtCW, ect). However what about the older games like CS. With the GF4 "new" mode of AA x4S, does this provide for any better handling of these older textures?

Thanks,

that 'improved' look comes from the fact that with accuview they blend-in samples from pretty far from the current pixel.

I thought that the 4xS AA used a blend of MS and SS AA. Wouldn't that account for the better handling of alpha textures? (MS didn't handle them, SS does)

Digitlife has screenshots of 4xS, but no alpha textures. The S stands for 2x super-sampling so this should antialias textures somewhat.
