A number of months ago I switched to an ATi video card (X1600 512MB specifically) after using nVidia cards for a long time. Obviously, FFXI uses very little in the way of GPU power and post-processing is just a pipedream for the Windower guys. However, with my ATi card I've noticed a significant drop in visual quality when it comes to mip-mapping texture filtering.
With my old nVidia card I could force Anisotorpic filtering and get a very nice texture smoothing effect for a great distance - even with drawdistance plugins and such. But with the ATi card, even when I force AF, the filtering distance is still very short and any textures rendered after that distance are very, very block and un-filtered.
I've tried fiddling around with forcing AA, AF, Catalyst AI, etc but nothing seems to make much difference. I've also tried the registry value changes and more often changing the mipmapping registry value to a higher number results in worse looks.
Given the large expanses of stone tiled textures in Aht Urghan it's really noticable and just looks like plain ass. Anyone have any suggestions for improving the visual quality on ATi cards or know of any tricks to get AF to stick over greater distances?
