That is why the R200 manages to slightly edge out the Geforce3 in fixed-function TL benchmarks. --- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

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 pgpRb0dLUiFNO.pgp Description: PGP signature

I'll switch over to fglrx tomorrow and run some tests...
