Created attachment 94113 [details] Results from gputest Hello. I noticed a performancedrop since git-6d1cecb on radeonsi using arch with mesa from the following repo: [mesa-git] SigLevel = Optional TrustAll Server = http://pkgbuild.com/~lcarlier/$repo/$arch I attach the results of: start_furmark_benchmark_fullscreen_1920x1080.sh Furthermore the unigine-valley performance decrease is from 26 to 22 fps.

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 [1] http://cgit.freedesktop.org/mesa/mesa/commit/?id=01e637114914453451becc0dc8afe60faff48d84
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.
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.
