I think the performance drop is caused by:
radeon: reverse DBG_NO_HYPERZ logic [1]
You can explicitly enable hyperz with setting the environment variable
R600_DEBUG=hyperz

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.

Fixed with
commit 14bdcc6ff98664552216acfdb7e35d0b128003ef
Author: Andreas Boll <andreas.boll.dev@gmail.com>
Date: Thu Oct 23 14:52:55 2014 +0200
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.
