Fairly obsure fact that its hard to find anything about on the internet, is that the original Radeons had a hidden feature to raise the anisotropic filtering all the way to 128X in OpenGL games. Screenshot comparison links seem to have all been posted in 2001 and all are dead. I was curious, and I managed to get it working just now, using an ATI Radeon 8500DV All-in-Wonder I just recently obtained, which was able to activate the feature using its initial launch driver 5.13.01.3276 (It didnt work on later drivers). The feature was meant for the original Radeon, but I guess it works on 8500 too. So, without further ado, heres the first comparison I was able to make, Serious Sam, with 2x zoom in ms paint to make it easier to see:
16X AF
128X AF
Immediately noticable is the blood splatters from the kamikazes I killed just before the savegame, do render from this angle in 128x, but are missing in 16x. Also distant tile textures do appear to be a bit sharper tho maybe also noisier?
No antialiasing on the pics btw, this card has FSAA 2x or 4x, and also SMOOTHVISION 2x to 6x, not sure which to enable or both, yet, will research this next
