Use the Liquorix Kernel instead of the default kernel in openSUSE Tumbleweed. It’s available for other distros too.
Or use CachyOS. Or Fedora Silverblue/Kinoite with CachyOS kernel. There’s no stuttering really on laptop, and got sick of it on desktop, so installed a different kernel.
I think the laptop is still faster though, but maybe because I’m playing at 4k on the desktop. Maybe get a 9060, before Cotton’s bill passes.
Also, laptop doesn’t have much running in the background like desktop. Both have the same amount of RAM, but I think the RAM type is faster or newer on the laptop. CPU is slightly faster. GPU is weaker, it’s in a eGPU enclosure too. Might be using subsampling on laptop too.
Update
Nope, not gone. Stuttering worse then before, all I did was do something on the other monitor with the game open. Now GPU is going under the minimum clock frequency in CoreCTRL. And it’s stuttering like a bitch. Taking forever to exit the game too.
Oh and Firefox crapped out, had to terminate it. Might uninstall this crap, and go back to official openSUSE kernel.
Just removed amd_pstate=active from my /etc/default/grub kernel args. Also removed the set default CPU governor. Was on powersave, but I use gamemode, so it sets it to a higher one. But might mess with whatever that kernel uses, don’t think it uses pstate.
If you look at /proc/cmdline, mine is intel_pstate=disable amd_pstate=disable BOOT_IMAGE=/boot/vmlinuz-6.14.7-lqx1-1-liquorix root=UUID=xxxx splash=silent quiet security=apparmor noresume iommu=pt amd_iommu=on transparent_hugepage=never idle=nomwait processor.max_cstate=5 cpufreq.default_governor=powersave usbcore.autosuspend=-1 amd_pstate=active mitigations=auto, notice before the BOOT_IMAGE, it says amd_pstate=disable. Hmm, maybe I should put that after BOOT_IMAGE. I’ll reboot and see if pstate is still enabled.
Still stutters a little, possibly. Lame. Probably because I’m listening to software radio at the same time. That uses CPU too. But after rebooting, it was more responsive, probably about the same as when I rebooted yesterday, but then slowed down overnight or something.
I think Fedora + CachyOS kernel is better. But I’m too damn lazy to switch distros.
