--- Comment #21 from Peter Wu lekensteyn@gmail.com --- Works now with the latest mesa and llvm. If the performance is still bad, you are probably affected by a bad workgroup size. In that case, try Tom's pyrit-perfs[1][2] patches on top of ac81b6f2be8779022e8641984b09118b57263128.
The second patch[2] is already upstreamed, but patch [1] does not apply on the current master because of other changes in the area.
