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?

      And if you go to sleep, sleep well to have good performance afterwards

    What’s your CPU? 6.12 has a lot of efficiency changes for both Intel and AMD. My immediate thought is this is power profile related. As a workaround, after waking from sleep, switch your power profiles to something else, then back to performance. See if that helps.

    Also check dmesg

      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.

    I run EndeavourOS and have to restart after my computer falls asleep. Have the thing set to 4 hours or whatever before sleep but sometimes it happens.

    I do not have the solution to your problem but I may have a hint. I had this exact problem years ago. The only thing I recall is that there is a difference between sleep and hibernate and maybe your computer goes in hibernation mode. Try disabling it to see if the cause is sleep mode or hibernate mode (or both).

    Sorry I don’t have the solution. If you find it, let us know!

      Good thought. Unfortunately I have confirmed the issue persists after sleep. Hibernation is disabled.

      Yes. The appropriate nvidia service units are in place.

        Yes. And those are all accounted for. Even toggled profiles off/on before playing. No difference.

    Same, Manjaro with kernel 6.6.65, all AMD Thinkpad E14 Gen 3.
