I don't have an R200, but the R200 registers related to vertex processing=20 are *completely* different from those on the R300. Now maybe the R200 has=20 both a dedicated fixed function pipeline *and* a programmable processor,=20 but unless that is the case, I assume fglrx on R200 tries to map ARB_vp=20 onto fixed function when it can, and falls back to software otherwise. Somebody with R200 hardware would have to test fglrx with the glxtest=20 dumping tool to find out for sure. cu, Nicolai |
