            Bug ID: 111082
           Summary: Severe stutter in CS:GO surf servers, despite ~300fps
           Product: Mesa
           Version: 19.1
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: nucrap@hotmail.com
        QA Contact: dri-devel@lists.freedesktop.org

In general playing CS:GO is going really well, however when joining surf
servers (a popular community game mode), despite having around 300fps the game
stutters really badly.

To test if you can reproduce you will of course need to have CS:GO installed
and join any surf server, for instance -> 217.79.188.156:27165

I hope somebody can reproduce this and maybe help :)

If nobody can, I might provide a video.

I am on archlinux with the following packages:
mesa v19.1.1, xf86-video-amdgpu 19.0.1

What makes you think this is a driver bug? Are you sure this is not just a slow
connection between you and the community server? Or a slow server or any number
of different things?

Sorry but I'm going to close this bug report as I see nothing to suggest this
is a graphics driver bug.

How is this not a graphics driver bug?

Under Windows 10 I connect to the very same server and there is no stutter.

I actually think this is a driver bug. This has nothing to do with my
connection.

He meant it could be a game engine bug (network or 3D, very probably).

You are both right.

CSGO 3D engine on based linux OSes is really bad if you use maps which are not
in the competitive set.

For instance, danger zone open maps, on my system, have disastrous
performance... and it is CPU related, not GPU, even though I have 8 core at
4.7Ghz (something is really wrong or litteraly CPU capped somewhere).

So maybe we should figure out if it is graphics driver related or a bug in the
CS:GO engine?

Why has this bug report been set to "RESOLVED FIX"?

I understand claiming that this might not be a graphics driver bug, but it
might pretty well be one. On which basis are reports closed here, on
speculations?

In the end I want to help the Linux ecosystem and make games work, because now
even though my own CSGO surf server is on Linux, I have to switch to Windows 10
to test it which is utterly ridiculus.

I did report my CSGO performance pb to valve devs:
https://github.com/ValveSoftware/csgo-osx-linux/issues/1111

I have no idea if my CPU bound performance pb is in the driver (which is very
likely since it's opengl), or the 3D engine.

Hm, well as I said my fps are constantly very high, so it looks like a frame
pacing issue. My CPU load is also super low and never above 50 % on a single
core.

Of course this might be an issue with the Linux implementation of CS:GO, but I
think it would be worth figuring out where exactly the culprit is. It can only
be those two things: CS:GO or the graphics driver..

This is the issue: looks like cpu capping in the 3d engine.
But, since csgo 3d engine is direct3d designed, this is why vulkan.

linux csgo devs are the ones who can profile properly their game and figure out
the culprit.
(could be linux networking related too).
