Hello, Here is a possible fix/hack to get _mesa_remove_extra_moves function in shader/prog_optimize.c usable. As far as I could tell with my testing there was an issue with this optimizing pass and OPCODE_MUL . I just added an exception to for this one instruction and made it easy to add others should further testing indicate they need to be added too. It bumped my Nexuiz scores on demo1 from 5,8,and 12 to 5,9, and 13. It also reduced the testing runtime from 234 seconds to 225 seconds. I have only tested on my radeon hd 3100 based laptop but would like to hear results from other types of cards too. Conn -- Conn O.

Linux has proved that if there are enough of you, you can advance just as far by stepping on each others toes.
