Arralen: Good points you've made. Having recently tried Doom 3 on my allegedly inferior-performing ATI card, I can say that it's OGL performance is more than acceptable. I get great graphics and decent frame rates (and that's with all the bells & whistles turned to max). So I'm left to ponder why Dom 2 (and only Dom 2) sucks on ATI? You just may be right in your hypothesis regarding bad code ...
