- implement Hierarchical Zbuffering along with fast Z clear (HiZ)
- reduce the CPU overhead
- figure out why the *F* Tremulous is so slow
There's going to be a Mesa 7.9 release soon. By then, I'd like all bugs to be fixed or worked around. HiZ might make its way to Mesa 7.9.1, but it will probably need a new kernel too.
There's also one very interesting feature being worked on by Corbin so stay tuned. Another developer Tom Stellard is currently working on the r300 compiler to implement missing GLSL features as part of his GSoC project.
