            Bug ID: 98996
           Summary: Counter Strike: Global Offensive performance
           Product: Mesa
           Version: git
          Hardware: Other

          Priority: medium
         Component: Drivers/Gallium/radeonsi

screenshot csgo native

This has always been problematic and since csgo is the second most played game
on Steam I do believe it warrants some attention.

Attached is a screenshot of csgo made with Linux 4.8 and latest mesa git with
gallium hud visible. It's 1920x1080 with the ingame settings set to lowest
(only multithreaded rendering enabled).

I believe the average FPS score pretty well, but the actual low FPS when there
is a lot of action on the screen makes it almost unplayable. The main issue
will probably be the low GPU load, it appears severely bottlenecked.

Hardware should be more than enough to get a smooth experience:
Intel Core i5-6500
XFX Radeon RX 480 XXX OC
2x 8GB Ballistix Sport LT Red DDR4-2400 UDIMM

screenshot csgo gallium nine

For comparison purposes, here is a screenshot of the windows version with
gallium nine. Same hardware, same software.

Note the high GPU load (It only has large drops when you die and it plays the
"killcam" animation), higher CPU load and much smaller buffer wait times.

Valve said lower performance is expected because of their shader translation
with togl, but this seems extreme.

performance with amd-staging-4.9 and mesa git

Screenshot with out of the box performance on latest amd-staging-4.9 and mesa
git.

I've implemented a "low fps" HUD graph
(https://github.com/ChristophHaag/mesa-mesa/commit/10d99ae2b8b87c72dc1c405d6ed3ef4a4eaf537f)
that calculates the FPS based on the longest time between two frames in the
period. Still not completely accurate since it's the time between two hud
update calls, but in my experience a good indicator. You can definitely feel a
slight stutter throughout the game.

echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level
improves it somewhat, but you still do not get smooth gameplay.

Might be worth investigating the buffer waits, e.g. 80 ms corresponds to almost
5 display refresh cycles.

--- Comment #4 from Timothy Arceri <t_arceri@yahoo.com.au> ---
There have been many performance improvements to the drivers since this was
reported, and nobody else has since complained of performance issue with this
game. I'm going to close this for now. Feel free to reopen with updated
information if this is still an issue.
