In general playing CS:GO is going really well, however when jo= ining surf servers (a popular community game mode), despite having around 300fps the g= ame 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 i= s not just a slow connection between you and the community server? Or a slow server or any nu= mber of different things? Sorry but I'm going to close this bug report as I see nothing to suggest th= is 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.

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 Window= s 10 to test it which is utterly ridiculus.
I did report my CSGO performance pb to valve devs: htt= ps://github.com/ValveSoftware/csgo-osx-linux/issues/1111 I have no idea if my CPU bound performance pb is in the driver (which is ve= ry likely since it's opengl), or the 3D engine.
Hm, well as I said my fps are constantly very high, so it look= s 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, bu= t I think it would be worth figuring out where exactly the culprit is. It can o= nly 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).
