I think it would give way better results in 3dgs when you'd use a model only level, compared to Sphere + 3dgs, I'd say these sauerbraten screenshots aren't that impressive at all.
Frank_G yes, shaders on block geometry is a fps killer, but that doesn't prevent us from taking the 'model only approach', right? We don't need Sphere to get shaders on wall models and the like either. I think that fps will be a tad lower indeed in 3dgs,
