I don't have an R200, but the R200 registers related to vertex processing are *completely* different from those on the R300. Now maybe the R200 has both a dedicated fixed function pipeline *and* a programmable processor, but unless that is the case, I assume fglrx on R200 tries to map ARB_vp onto fixed function when it can, and falls back to software otherwise. Somebody with R200 hardware would have to test fglrx with the glxtest dumping tool to find out for sure. cu, Nicolai
