With Francois' help I could build a test package for 3DMark2000 now:
http://stud4.tuwien.ac.at/~e0526822/3dmark2000.tar.bz2
It runs two tests, one at 640x480, another one at 1024x768, writes the results to a file and reads the file back. No benchmark results are sent to the server yet(just ok / fail).
Stefan, this link is not valid anymore, could you make the file available again?
Thanks, Martin
