That page seems to lie. The R500 limits are: - 1024 vertex shader instructions - 512 fragment shader instructions You should get these values from 'glxinfo -l'. Some of the shader model 3.0 requirements are: - minimum of 512 instructions must be supported in both vertex and fragment shaders (met) - GL_ARB_shader_texture_lod (not met) The latter appears to be the culprit.

It seems this depends on how many native instructions are available for ARB_FRAGMENT_PROGRAM. r300g reports 512, but according to <a href="http://opengl.demoscene.fr/reports/ATI" target="_blank">http://opengl.demoscene.fr/reports/ATI</a> Radeon X1950 Pro.htm this card should support 1024. If the information listed in GLinfo isn't wrong, is this a limitation in r300g, or is it possible that it doesn't take full advantage of the cards capabilities? (I guess it's also possible that I have completely misunderstood either Wine or something else of course!) -- Cheers, Sven Arvidsson <a href="http://www.whiz.se" target="_blank">http://www.whiz.se</a> PGP Key ID 760BDD22 _______________________________________________ mesa-dev mailing list <a href="mailto:mesa-dev@lists.freedesktop.org">mesa-dev@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/mesa-dev" target="_blank">http://lists.freedesktop.org/mailman/listinfo/mesa-dev</a> </blockquote></div>
