I've been meaning to ask this but I have been waiting for someone to make a detailed analysis of the new optimization options in the 65.xx drivers and up.
As many of you know these drivers have options for anistropic filtering such as:
*Trilinear opts
*Anistropic mip filter opts
*Anistropic sample opts
Now these options are quite different than the 61.77 drivers and below.
Does anyone know what exactly Anistropic mip filter opts do? I don't notice any more graininess with them on so I always keep them on, But I have no idea what these are supposed to do.
Also about the Anistropic Sample opts...this setting is a mixed bag for me. On one hand it seems to boost overall framerate tremendously but it makes grainy mipmap artifacts all over the place. In most games it looks just plain ugly. Even old games with low resolution textures are grainy between every mipmap transition. What exactly is this setting doing?
Overall I've given up trying to get rid of mipmap graininess on this card, but even if settings are at High Quality in the drivers the graininess is still there albeit not as bad. I guess it is an eyesore I get to deal with though if I want playable framerates. I remember I used to complain on rage3d when I had a 9800pro about bad texture banding. I've come to this conclusion about the 2 card comanies
ATi=banding NV=grainy as far as texture filtering goes.
I wish there was some way to really fake trilinear filtering but there just doesn't seem to be. I hate the performance hit of true trilinear but I also hate the artifacts of trylinear. Don't know which is worse.
