[Solved][amdgpu]severe graphics regression on 6.4.1

Hello,

since the linux kernel upgrade to the 6.4.1.arch1-1. I get a less than 20 fps and extremely bad lags in game genshin impact on my pc with 6900xt and 5600x,
when i switch to 6.3 or earlier, it is stabled 60fps and I have a normal smooth game experience

I have found this issue some time ago when I install and use the linux-mainline or linux-amd-drm-next when the official kernel release is 6.3

and now, the linux 6.4.1.arch1-1 have been release and archlinux has got the upgrade, I get a default  6.4.1.arch1-1 kernel and a terrible gaming experience

I change all the other conditions, and have no effect. The only thing that works is downgrading the kernel to 6.3 or earlier.

I also checked the kernel debug message(journalctl -k) and nothing helpful found

Is here anyone encountered the same issue? any workaround can temporarily avoid this issue in 6.4 kernel?(because I want just use the official linux package)

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

Is the issue present in the current linux-amd-drm-next ?  Have you located the commit that introduced the issue?  Have you reported the issue upstream?

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

Quick workaround is to switch to official linux-lts package and submit a bug report upstream hoping to be fixed before the bug reaches lts too.

Cannot personally test your issue.

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

I think I have found the cause of the problem, the gpu memory clock is locked, I watch this value via cpu-x for a while and the value is always 96Mhz

yes, get same result

sorry, not yet

may take some time for me to search and read the relative commit in the kernel code

thanks very much, but I searched the solution by google keywords "amdgpu mclk 6.4"

https://gitlab.freedesktop.org/drm/amd/-/issues/2657

according to the discussion from the freedesktop thread above,
the tag amd-drm-next-6.5-2023-06-16 fixed the issue,

Good news: It's fixed with tag amd-drm-next-6.5-2023-06-16 , VRAM correctly clocks up and down with 165Hz. Will close once fix is in mainline / stable.

I will find a way to upgrade it from tag 2023-05-31 now to tag 2023-06-16 in my arch

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

Hey, I just upgraded to an AMD gpu only to discover this issue as well!

I did find a sort of workaround though? For me, when I suspend and wakeup my system, the VRAM speed gets set to the max 1000MHz. Unfortunately it seems to stay at that speed, but at least the performance is better.

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

I had this issue on 6.4.2.arch1-1, although I didn't check the GPU Memory Clock, so I can't say for sure.  It's fine on 6.3.9-arch1-1.

Do you have this issue on the latest 6.4.3.arch1-1 ?

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

Having an AMD Ryzen 7 5800X3d with an AMD Radeon RX6600XT I can confirm that since 6.4.x the graphic performance is worse. I am able to solve these issues by one of these:

- disabling FreeSync in the monitor settings
- changing the refresh rate in Gnome Display Settings below 120Hz
- downgrading the kernel to 6.3.9-arch1-1

The latest kernel release (6.4.2.arch1-1) did not solve the issues.

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

This is not solved,

On 6.4.4-arch1-1 and corectrl reports the GPU  memory clock is stuck at 96 MHz.

I also have 5800x3d as debellator, but radeon 6700xt though, shouldn't be a big difference.

I however refuse to use the refresh rate below 120hz or disable freesync, so I am staying on 6.3.9.

Re: [Solved][amdgpu]severe graphics regression on 6.4.1

OP (lechain) has stated several times their issues are solved with latest 6.4.x kernel.
Pulec, Debellator : you appear to have different problems then OP, please start your own threads.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
