Low performance on Lenovo C13 3500C

Already reported this in the discord, but putting it here for a more permanent record.
Basically, the GPU isn’t clocking over 200mhz unless you set it manually.

  • I haven’t tested additional distros, but I’m on Arch running Gnome.
  • Someone suggested I use CoreCtrl to set performance, but setting fixed high performance crashes the laptop.
  • Manually setting clocks to max out at 1150 is the current solution I’m running with.

This is for the C13 Yoga, yes?
I’ve only tested Fedora 39 Cinnamon here so far on this. I’m not on the discord but I’m here on the forum- what are you using to record the GPU clock issues? Radeontop?

May I ask how you were checking the iGPU clocks? I’d like to do some testing on mine as well.

try updating your coreboot

Ah, sorry for the late reply. Don’t check forums that often.

I was using CoreCtrl to change and get a general idea of where clocks were at.

I’ll try updating coreboot - did it work for you?

I haven’t updated my coreboot in a bit, due to the trackpoint being enabled on my older build, as imho the C13 Yoga trackpoint is superior to a trackpad experience:

# dmidecode 3.5

But I also haven’t had any video playback or Risk of Rain Returns issues on this machine.
Also currently running openSUSE but I can throw Fedora or another distro back on here to do further testing if you would like.

Oh, update, yeah, the trackpoint is working now and you shouldn’t see any performance hits:
