Hello,

I am trying to figure out how to debug stuttering in games. I have applied the UDEV to force 3D_FULL_SCREEN + COMPUTE and I have not been able to figure out whats causing my PC to microstutter. Yes, TPM is fully disabled, so I instantly ruled that out. I have been working at this for a couple weeks and how the problem arises is I play a game and after around 5-10 minutes itll stutter to around 70 less fps (240 > approx. 170 and usually when its an important fight) and happens in BOTH vulkan + opengl. I cannot find any errors that can point to the route of the issue, and I do not use VRR. My gpu is the Amd Radeon RX 6800xt + AMD Ryzen 7 5800. I am using Hyprland, but it runs flawlessly besides the stutter in games. I can consistently get 240fps in all games I play, but it randomly stutters if that makes sense. I also used the LTS kernel for xanmod but it has happened on linux lts as well.

AMD systems typically use a firmware TPM (fTPM) provided by the PSP (Platform Security Processor), are you sure you have disabled the PSP?

I switched to windows to test other games because I wanted to make sure it wasn’t hardware and I don’t get any stuttering

Alienware only provides FTPM option that is disabled I don’t see any fTPM

Does bootctl say that TPM2 is disabled?

#

AMD has faulty fTPM RNG

I will let you know soon

#

Just woke up

#

I am gonna reinstall arch

fringe fjord Does `bootctl` say that TPM2 is disabled?

However, this should not be a problem in the future due to this patch https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=554b841d470338a3b1d6335b14ee1cd0c8f5d754

The kernel will disable the fTPM RNG indiscriminately on all AMD platforms,

#

I think it merged in 6.5.

Do you think although ftpm is disabled it is still toggled

#

Cause the stutters started 2 weeks ago

Until the journal log is posted, there would be no conclusion

journalctl -b0 --grep=tpm | curl -F 'f:1=<-' ix.io

Alrighty

Can you rule out the compositor?

fringe fjord Can you rule out the compositor?

I don’t think it’s Hyprland

#

it ran across Gnome, and KDE

#

I think it might be amd power now
