Actually, why is the state tracker doing the min/max computation at all? If the driver does the index lookup itself, as opposed to using an hardware index buffer, (e.g. the nouveau drivers do this in some cases) this is unnecessary and slow.
Would completely removing the call to vbo_get_minmax_index break anything? Also, how about removing the max_index field in pipe_vertex_buffer? This seems to be set to the same value for all vertex buffers, and the value is then passed to draw_range_elements too. Isn't the value passed to draw_range_elements sufficient? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
