Great work Humus!
I don't know if anyone tried this but I increased the texture files, from their default (either 256*256 or 512*512) to 1024*1024 and then to 2048*2048... the frame rates I was getting (about 60fps on my Radeon 8500LE) remained the same. Texture qulaity did seem to improve but I can't be sure if what I did had any impact really.
Still, very nice work Humus :smile:
