Degraded gaming performance after waking from sleep. (lemmy.world)

Operating System: Arch Linux 
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1
Kernel Version: 6.12.7-arch1-1 (64-bit)
Graphics Platform: Wayland
GPU: NVIDIA GeForce RTX 4090/PCIe/SSE2
GPU DRIVER: 565.77

Pretty straight forward issue.
Rocket League for example: Butter smooth game play before sleep. After sleep mild to moderate stuttering.

  • Looking at processes, I don't see anything hung or stuck using high resources...
  • I've tried restarting sddm and kwin_wayland --replace.
  • Scanned logs before and after sleep, didn't see anything stand out.

I feel like this started happening around the first release of the 6.12 kernel. Or maybe last couple NVIDIA driver releases. With that in mind, since it's the 6.12 kernel, I have set my scheduler to "scx_lavd --autopilot".

Anyone experiencing similar issues?

Hi there. i9-14900K

On my setup, game launches automatically trigger the CPU Scheduler/Governor/Energy Profiles to Performance.

So went ahead and switched the CPU Scheduler, Governor and Energy profiles to defaults and powersave. Then put them all back to performance. Game is more than playable, its just not the same buttery smooth it was before the sleep.

Thanks for the suggestion.

Edit: dmesg

I have scanned my logs like I mentioned above, which includes dmesg and nothing stands out during wake or sleep.

Isn't that the chip that physically degrades?

I haven't been following that fiasco very closely. Did Intel ever recall and replace the chips? If not, that could be your problem and there's nothing you can really do about it since the CPU itself is flawed.

Unfortunately these chips had voltage issues on launch. Whenever I do a new build I manually tweak my CPU in the bios while also testing my configuration using stress / torture tests on prime95 (mprime). They have since released bios updates that address the voltage issue. My understanding is the chips do not "degrade" over time, but instead could experience "damage" when used on a unpatched bios. More so when using the advanced overclock settings.

that could be your problem and there’s nothing you can really do about it since the CPU itself is flawed.

I don't think so. This is a Linux bug. This bug doesn't exist when booting into Windows.
