Final fantasy 8 is an example.

The reason is, that ATI cards don't natively support 8 bit palletized textures and table fog. One of the 2 had a software emulation but I don't remember the deatails. The same problem will occur in geforce cards newer than the Geforce 5 (FX) series, as that is the last generation with hardware support for those 2 features.

-8 bit palletized textures - afaik only like 2-3 games are affected by that, and said games are probably better on console anyways?
-table fog - I couldnt find a list of games with that. I did learn tho, that the older radeons like 8500 can enable table fog support with a registry tweak of some sort

Check here: Table Fog & 8-bit Paletted Textures

I see, theres a few... but overall, not too many. I will try to get these working to see whats the deal with them. BTW is that all? 2-3 games requiring palletized textures, and 5-6 requiring table fog? I was under the impression theres plenty of games that would work on nvidia 6000 series but not on ati radeons... guess this was about the DOS VESA games
