[Mesa-dev] Heavy ioq3 regression in mesa (r600g/cayman/aruba)

[Lauri Kasanen]

Hi,

Tremulous and Smoking Guns regressed in Mesa master, ok in 020c43f,
broken in 4ddf51db.

Tremulous 133 to 33 fps, Smoking Guns 153 to 40. In the ok version,
hyperz was enabled by default; in the more recent master, it was
disabled by default, but enabled via the R600_DEBUG env var. The env
var applied correctly, because other games' perf reacted to it.

This is a week old master, so it might be fixed already; just in case
it's not, I thought I'd report this, as a release is about to be
branched. Wouldn't do to have 4x regressions in a release ;)

Anyway, that's a fairly wide area to bisect, and I'm busy with other
things, so just this email instead of a bug and a bisect.
