Reading this post, I tried i915g and i965. I tried this, with no progress whatsoever. So I tried to figure out which driver it used. Now, for a short while I used Ubuntu (which I otherwise avoid), in which most viewers worked almost like the above-mentioned Snowglobe, which means acceptably well. Thinking that perhaps compiling a SL viewer standalone in my system would give equally good performance, I tried to do it with my favourite viewer, but it fails miserably. This viewer works perfectly, I can play in Ultra graphics, which means my card has the ability to do it.

I play secondlife and most viewers don't even give me basic shaders, with one exception. It's not that it doesn't work well (glxgears gives about 85, the same as my refresh rate), but I'd like it to work better for gaming.
