The reason I came to this was that I wanted to compare some program's execution using swrast and a hardware driver, and changing LIBGL_ALWAYS_SOFTWARE=1 to =0 seems very much like it should *not* still use software. It's counter-intuitive, and it's hard to understand why LIBGL_ALWAYS_SOFTWARE set to false should use software renderering. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
