I'd like to bump this too. For reference, TF2 has a netbook mod, which essentially remodels most of the characters into fewer polygons, and turns off all fancy stuff (even shadows). Using that, I went from 10-15 FPS in TF2 to 45+ in one 6 MB patch. I've tried going through the ini files to reduce complexity, but to no avail. So if anyone's willing to make a reduced polygon model mod, I'm sure there will be a lot of takers.
