Poor iGPU gaming performance on a Ryzen 5 6600H laptop (redmibook pro 14 2022)

[RealKomander]

So recently I decided to give Linux a chance and installed Mint on my laptop in dual-boot with existing Windows 11 instance. The installation process was smooth: I downloaded all the necessary programs and made sure that my graphics drivers are working. To test gaming performance, I downloaded Minecraft and imported the very same optimization modpack that I was using on windows. In the end, I got around 90 FPS without shaders and 0-1 FPS with shaders. Compared to 500 FPS on windows, this was quite poor. Then I tried Linux Arch, and it disappointed me even more with staggering 13 fps...

After various troubleshooting attempts with ChatGPT, I eventually gave up to solve this on my own. Am I doing something wrong? Or is my iGPU cursed to not work properly on Linux?

Did you try the game without the mods you used for Windows?

Yes, here are the screenshots

This is on my arch system. The GPU is struggling a lot

Sadly, I don't know anything about that particular game. I was merely eliminating a possible cause.

Until someone else comes along (I am not sure if we have any Minecraft players here), I'd poke aroundin the settings. You can do things like adjust how many blocks you see on your screen (I'm pretty sure) and stuff like that.

Also, did you install this natively or is it installed via Steam? That's going to be another possible cause/something you can try.

I'm more a retro-gamer kind of guy, at least for the moment.

I'm sure it's not the game's problem. I ran ungine heaven basic benchmark with 18 fps average and 455 points - there's clearly something wrong with the system or video drivers. Other 660m iGPU users report 1600 points, and I can run the same benchmark on windows if needed to check that I'm getting the equivalent score.

I'd wait and see if someone else comes along. So far, we've eliminated a couple of things - which is good and will save them time. We have members all over the globe, some with different experiences and subject-authority.

So, for now I'd just wait a bit to see if someone else pops in.

And here are the results I get on windows - 1280 points in the benchmark, 120 fps in vanilla minecraft. The benchmark was broken and didn't let me take a screenshot...

What is the output of ..

glxinfo | grep OpenGL

You might try to install glmark2 and running the default tests.
That way you would know if it's your video card, or something in your game.

edit: also, can you post the output of...

dpkg --get-selections | grep amdgpu

Have you tried CoreCtrl? Some distros don't have it preinstalled, but it's a must for any AMD APU owner. It lets you control TDP, GPU clocks, and fan curves. If you're stuck with low clocks, that might be the culprit. Also, double-check your kernel version. Older kernels sometimes have issues with newer hardware.

Here's my output for "glxinfo | grep OpenGL":

"dpkg --get-selections | grep amdgpu" returns nothing. What does that mean?

My glmark2 score is 4757.

It turns out I'm indeed stuck with low clocks, but when I increase them, the performance doesn't change, but my temps skyrocket and my fans go crazy. Still getting 12 fps with GPU locked at 1900mhz...

That is a pretty low benchmark indeed.
It doesn't look like your amd video driver is installed; I wouldn't think your card is too old to support it.

In post #1, it seems you are using mint.
In post #3 it seems you are using arch?

For Mint

sudo apt install xorg-video-amdgpu

Then check to see if it's installed.

lspci -k | grep -i amdgpu

Then I would reboot and see if that helped.

For Arch, I don't use arch much these days, so I looked this up on google.

sudo pacman -S mesa xf86-video-amdgpu lib32-mesa vulkan-radeon

lspci -k | grep -i amdgpu

Hopefully that's correct, maybe one our Arch experts can give better instructions?
