I noticed a performancedrop since git-6d1cecb on radeonsi using arch with mesa from the following repo:
SigLevel = Optional TrustAll
Server = http://pkgbuild.com/~lcarlier/$repo/$arch

You can explicitly enable hyperz with setting the environment variable R600_DEBUG=hyperz
I confirm this. Thanks.
We keep this bug open until hyperz gets re-enabled by default.
Yes I confirm too. HyperZ gives a serious boost.
In the Counter Strike: Source Video Stress Test I was at 46,65 FPS with a RV770, and now at 37,90 FPS without HyperZ.

radeon: enable Hyper-Z on r600g and radeonsi by default
This reverts commit 01e637114914453451becc0dc8afe60faff48d84.
Since then many Hyper-Z issues have been fixed or worked around.
Enable Hyper-Z by default so that we get enough feedback for the upcoming
mesa 10.4 release.
If you have issues with Hyper-Z try to disable Hyper-Z using the enviroment
variable R600_DEBUG=nohyperz and please report the issue on the bugtracker.
