Hi, I did some profiling with perf under nexuiz and found that st_finalize_texture function was one of the most cycle consumming. (~1,50% whereas darkplaces took ~30%)
I rewrite some part of this function to make it a bit faster ; with these 2 patches, st_finalize_texture consumption went down to ~1%, so a 40-50% boost. This does however not translate to more fps to Nexuiz : if there is any improvement, it is not noticeable (too much noise in measurements). On the other hand, the function has become less readable. I had to manually unroll loops and use intermediate values (gcc does not do it automaticaly, using default parameters). Of course I think that we should make less call to this function to see a true gain, but this would require more work.
