Operating System: Arch Linux 
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1

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?
