Hi,

It was visible at all VRAM sizes (both 256mb limited, and 768mb full).
I also used hyperz to rule it out, ie 

R600_DEBUG=hyperz phoronix-test-suite run pts/tremulous pts/smokingguns

It's possible this bug only affects Cayman and/or APUs. Though just
recently a similar ioq3 regression was reported on Intel.
