Low performance and low GPU usage with Tomb Raider (Linux native)

Hello, I have been experiencing performance issues with my AMD R9 280X graphics
card for several months.

On all games (Linux native and Proton), my performance is very low, well below
the capabilities of the graphics card.

The problem occurred when I migrated my system from Windows to Debian 10. I
updated Debian stable to sid in order to have the latest version of the kernel
and mesa.

When I launch a game, the performances are low and during very complex scenes,
the framerate goes down to 10/15 fps with a very low GPU use ~ 18%. The only
time I've seen GPU usage hit 98% is in the main menu in Dawn of War II.

Changing the graphics settings or the screen resolution changes absolutely
nothing.

The only game that seems to work well is Shadow Warrior, whose GPU usage rarely
exceeds 70%.

I have never heard the fans work since my transition to Debian so I used the
radeon-profile tool to make sure the fans work manually.

I forced the use of the hight profile in order to increase the memory and
processor frequency as much as possible, but no difference

Do things work any better when using the radeon kernel driver rather than
amdgpu?

Hello, with the radeonsi driver, the performance is lower than the amdgpu
driver. On the same scene in Tomb Raider, the graphics card displays ~ 10fps.

I have a lower score with glmark2:

radeonsi is the mesa OpenGL driver and runs over both radeon and amdgpu.  Are
you actually using the radeon kernel driver?

Yes, i use the radeon driver after comment this line in
/etc/modprobe.d/blacklist.conf :

#blacklist radeon

Actually i run on radeon driver.

Re: [Bug 206231] R9 280X low performance with all games

[sylvain.bertrand]

Owner and user of tahiti parts on amdgpu with a state of the art gfx stack
poping in.

I own "rise of the tomb raider" which gnu/linux port is vulkan only, and vulkan
is only available with the "amdgpu" kernel module (as far as I know).

I have not bought "shadow of the tomb raider", which is vulkan only too (the
port was coded by the same company).

I did clear "rise of the tomb raider" years ago, I cannot play it anymore
because the driver seems to miscompile some shaders and does gpu vm faults
(from my save file). I did open a bug.

I heard 'southern islands' parts (tahiti...) do suffer from a critical "mip
mapping" slowdown bug. That could explain the slugginesh of those hardware
parts in 3d intense games (I did almost stop playing "rise of the tomb raider"
because the 3d rendering was unpleasantly not smooth enough).

If you want, we can try to compare our benchmarks?

--- Comment #7 from kentosama (kentosama@whiteninjastudio.com) ---
I noticed something strange. When I do the Tomb Raider benchmark, the GPU usage
is 100% and I hear the fans running at full speed after a few seconds.

The bench gives a result of a minimum of 37 fps, a maximum 70fps and an average
of 55.3fps with the graphic parameters on ultimate.

There is something wrong, because during the "slum" sequence, I get a 10/15 fps
framerate with a ridiculous GPU load.

Sure, but I only have the first Tomb Raider, the one released in 2013 it seems
to me. Do you know a command to record the game framerate log ?

This seems to be from "shadow of the tomb raider" which I don't "own".

Do you "own" "rise of the tomb raider", the previous tomb raider game (which I "own")?

Wow, this from the first tomb raider, the one from 2013!! (7 years ago).

Sorry I read the emails in the wrong order.

I don't know own this game, sorry. Another game perhaps?

The framerate with CS GO is not good with graphics on "high". I tried the Dust
II map and I get a maximum of 90 fps in some places, a minimum of ~ 50 fps
looking towards "middle" where the main door is.

It seems very weak to me.

For Dota 2 with Vulkan, the game runs at more than 100 fps in some places, but
with a some elements on the screen, it's more around ~ 60fps. I noticed that as
with other games, GPU usage is always low when there is a need for performance.

Still the unreadable screenshots. huh??

> I use Gallium HUD with this options :

Gallium HUD does not work with vulkan (as far as I know), hence for dota2 vulkan.
In dota2 you have an option to display the 3d engine(valve source2) fps.

In cs:go, there is a way to enable the 3d engine(valve source1) fps display.
It is via the "console", see google.com.

> My is CPU is an AMD FX 8320

I have a FX9590, then our benchmarks should be mostly the same.

I downloaded the Vulkan DLC and active the FPS in Dota 2. I get between ~80 and
90 fps :

For CSGO, i get between ~70 and +100fps :

I have ~ the same for competitive maps.

For danger zone maps, namely big open maps, csgo 3d engine has disastrous
performance. Valve is aware of the problem. It seems there is a kind of cpu
cap somewhere since max or lowest 3d settings does not seem to impact
significantly the performance.

Don't forget: I heard southern island parts suffer from a critical mip mapping
bug/slowdown.

----

The real benchmark is how much time and how often the fps goes below 60 in the
worst realistic conditions (average does not matter).

---- 

I did re-install "rise of the tomb raider", I still get gpu vm faults.

If I recall properly "bioshock infinite" is gpu nasty even though it is a GL
game.

Indeed, this is obvious here

This vid rekt of the mip mapping hardware slow down bug... but I may be totally wrong
due to the insane complexity of the GL stack.

Only the AMD/mesa devs can reasonably deal with the insane complexity of the GL
stack (linux(drm) + libdrm + llvm + mesa(GL) + xserver + xf86-video-amdgpu).

But they won't be able to do anything if you don't run the latest git version
of the code (linux + mesa) and provide an easily reproducible and free (as in
free beer) case (or some AMD/mesa devs own your games).
--------------------------------------------------------------------------------
I run such a 64bits system. If you can reproduce the issue with a free (as in
free beer) game, I'll be pleased to test it to see if it happens on my system.

or

You would need to compile and run the following linux kernel:
"git://people.freedesktop.org/~agd5f/linux branch", "amd-staging-drm-next" branch

Unfortunately, Southern Islands hardware shader compiler is llvm, you would
need to compile the latest git llvm-project (a massive pain).

Idem for libdrm, mesa, the xserver, and the amdgpu xserver driver.

Is this roughly the same model every GPU vendor uses. GPUs are complex.

No offense intended! It is obvious that the maths being the same for everybody,
sensible hardware models will all look alike. It was more to underline the
significant "technical cost" difference between GL and vulkan.

To come back to this issue, I was willing to help this user "secure" a real
issue by reproducing it (since I run everything git) and provide a reasonable
context (free as in free beer) for you guys.

I tried to compile the kernel "amd-staging-drm-next" but it's a horror, nothing
works during compilation.

I just tried Dirt Rally which a Vulkan game, the performance is not good. I get
an average of 30 fps at the benchmark result while the game is supposed to run
at 60 fps in ultra setting.

Could changing distrbution help?

Re: [Bug 206231] R9 280X low performance with all games

[sylvain.bertrand]

Dirt Rally is a GL game, not a vulkan game.

It happens I have it in my library even though I don't recall to buy
it.

Anyway I did run the included benchmark:
  - cpu governor to performance
  - monitor refresh rate 144Hz
  - 1920x1080
  - 8xmsaa
  - _no_ vsync
  - everything to max

avg fps: ~48fps
low fps: ~30fps
max fps: ~60fps

I get several GPU vm faults in dmesg too, but no crash (like in vulkan "rise of
the tomb raider").

Re: [Bug 206231] R9 280X low performance with all games

[sylvain.bertrand]

Actually I should have restarted the game.
I did reboot in a clean state and did set "performance" on the gpu as well.

Here are the results of "clean" benchmark run:
avg fps ~ 20fps
min fps ~ 15fps
max fps ~ 40fps

Still getting gpu vm faults in dmesg.

Indeed Dirt Rally is an OpenGL game. I thought it was Vulkan, because I didn't
see the HUD from Gallium, but it was an error in the settings.

The result benchmark in ultra (1920x1080, 8xmssa, no vsync):
avg fps ~ 23fps
min fps ~ 15fps
max fps ~ 31fps

Re: [Bug 206231] R9 280X low performance with all games

[sylvain.bertrand]

This is consistent with what I have.

I did a clean benchmark run, but this time everything to low/off, but still
1920x1080:
avg fps ~250fps
min fps ~200fps
max fps ~350fps

Still getting gpu vm faults in dmesg.

I run everything git and amd-staging-drm-next no older than 1 week.

Is there a reason to have such poor performance with Dirt Rally compared to the
Windows version which should run at an average of 70fps during the benchmark? I
noticed that the GPU load was low on the benchmark unlike other circuits where
the GPU load is 100%.

Ok. What settings did you use in the benchmark to compare dirt 3d engine on
windowsDX and linuxGL(mesa)? all to max(often ultra)/on?  with msaa?

We must run exactly the same settings.

Ultra settings with 8xmsaa, no vsync and 1920x1080.

I base myself on the different benchmarks visible on Windows in ultra with the
R9 280X and 8320.

I did a benchmark with the settings on low, no xmsaa, no vsync:

So you say that: everything to max/ultra/on + 8xmsaa an 1920x1080, on windows,
you get avg 70fps? yes or no? If yes, what are the max and min fps?

No, I do not have Windows on this computer. There are several benchmark results
available, moreover I noticed that Mesa has much lower performance compared to
DirectX on Dirt Rally and other games.

I was convinced that Mesa was equivalent to DirectX, but it seems that OpenGL
is much slower. It could therefore be "normal" performance if Mesa 3D is
actually slower than DirectX.

I just compiled mesa from the git. I don't expect a difference in performance
meaning, but I can hope so.

ok. Then we don't have numbers to compare to and weight how much mesaGL is worse
than dx for dirt rally 3D engine (modulo the hardware bugs/gpu vm faults/etc).

I guess, one would use the presets to get a min fps close to 60fps and ajust
with the advanced settings.

--- Comment #39 from Jacques Belosoukinski (kentosama@whiteninjastudio.com) ---
I did different tests and there is a real bug.

With Dirt Rally in ultra, if I use 8mxsaa, I have miserable performance. If I
set 0mxsaa in game, the performance is + ~60 fps. If I reactivate the 8mxsaa,
the performances are very good between ~50 and ~70 fps. This is not normal.

With the game Dawn of War II, the framerate is ~48 fps in ultra, high, normal,
low.

It is really very strange.

I noticed that the performances are good after a big lag. This was the case
with Dirt Rally, on a race, the game freeze for a few seconds then suddenly,
the game run with than ~ 60fps.

In the game Dead or Alive 5 (Proton), the performances were from ~ 40 to ~
50fps. After a lag, the game worked very well at 60fps contant.

Yep. this looks like a real critical software and/or hardware bug. Like the one
you did show it the tomb raider vid.

If you could reproduce with a free game, that would be better for the amd devs.

I'll fool around a bit more with dirt rally (don't forget to restart the game each time
you change the settings...)

The core version of Dead or Alive 5 is free :
https://store.steampowered.com/app/311730/DEAD_OR_ALIVE_5_Last_Round_Core_Fighters/

The game works well, but as I reported, the framerate is very low during the
first few minutes of play. I don't know if this is a problem with Proton or
Mesa. I keep looking for free or popular Linux games, but there isn't much.

Re: [Bug 206231] R9 280X low performance with all games

WOW: I did reproduce with dirt rally. I could not see it because the game must
not be restarted to "uncripple" the renderer. I used the number or rendered frames
and I go from an horrible 3000-5000 frames to a wooping 11000 frames, not to mention
the game is now ~playable to max/ultra settings. I had to run 2 times in
a row the benchmark to "uncripple" the renderer, or fool around with the msaa
settings (without restarting).

And I get ~11000 frames with msaax8 or msaaoff (and I can clearly see when it
is on or off).

Since you can reproduce with other games-->Yep, it is very probably a set
driver/weird hardware critical bugs (modulo the numerous visual glitches and
gpu vm faults).

@alex: this one is nasty and probably will ruin the gaming experience (and
benchmarks!) on many games.

(@Jacques: Proton games do not do. Only native GL and/or vulkan, that to remove
any proton bugs)

The first time you run the game the shaders are not cached and you may see
large compile times.  The next time you run the game the shaders are cached and
you avoid the compiling delays.

I did not erazed the disk shader cache since the first time I did run the game. Then
the game is loading the shaders straight from the disk cache.

In other words, this presumes the shaders submitted for compilation by dirt
rally engine are different each time the game is run ???

It may be related to the brand new mesa/src/gallium/auxiliary/util/u_live_shader_cache.c

I don't know the inner details of this (I stay away from anything GL), but it
seems there are some GL shader usages which which will trigger a full
compilation of an already compiled shader.

@alex, maybe that's what you were talking about?

As I said, I may be totally wrong though.
