I remembered that I still have an XP partition around, so I ran GLinfo myself, and it seems to report the same: http://whiz.se/temp/x1950pro.htm I guess the application itself could be buggy though, is there any other way of confirming the number of instructions? > You should get these values from 'glxinfo -l'. Right, that was what I compared the GLinfo output with: GL_FRAGMENT_PROGRAM_ARB: GL_MAX_PROGRAM_INSTRUCTIONS_ARB = 16384 GL_MAX_PROGRAM_NATIVE_INSTRUCTIONS_ARB = 512 GL_MAX_PROGRAM_TEMPORARIES_ARB = 256 GL_MAX_PROGRAM_NATIVE_TEMPORARIES_ARB = 128 GL_MAX_PROGRAM_PARAMETERS_ARB = 64 GL_MAX_PROGRAM_NATIVE_PARAMETERS_ARB = 256 GL_MAX_PROGRAM_ATTRIBS_ARB = 12 GL_MAX_PROGRAM_NATIVE_ATTRIBS_ARB = 10 GL_MAX_PROGRAM_ADDRESS_REGISTERS_ARB = 0 GL_MAX_PROGRAM_NATIVE_ADDRESS_REGISTERS_ARB = 0 GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB = 1024 GL_MAX_PROGRAM_ENV_PARAMETERS_ARB = 256 GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB = 16384 GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB = 16384 GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB = 16384 GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB = 512 GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB = 512 GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB = 511 > 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. Seems like Wine only enables 3.0 if the number of instructions exceeds 512, probably just to play it safe. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
