Nvidia 560 driver stuttering

Hi all! Just wanted to quickly post my findings regarding the newly released nvidia 560 drivers.

As you may know, the open source kernel modules are now the recommended way of using the driver. However, at least when using KDE with wayland, you’ll notice some stuttering as is also mentioned by someone here.

So the best way of handling things is unfortunately to still use the proprietary kernel modules with GSP module turned off.

So just nvidia-inst --32 (or nvidia-inst --32 --no-dkms if you like) and put nvidia.NVreg_EnableGpuFirmware=0 into your kernel parameters.

Quick reminder: if using systemd-boot, put nvidia.NVreg_EnableGpuFirmware=0 into /etc/kernel/cmdline and apply via sudo reinstall-kernels. If using grub, put nvidia.NVreg_EnableGpuFirmware=0 into /etc/default/grub and apply via sudo grub-mkconfig /boot/grub/grub.cfg

With this it’s all smooth sailing. I’m playing Deadlock atm and got 80-320fps on lowest settings (I’m on a 3080 Laptop GPU), which is a huge improvement over the 555 driver, which left me at 70-100fps

I haven’t noticed any stuttering. Have a 3080 desktop also on plasma wayland, so your mileage may vary. I recall from the release notes that the 560 drivers were supposed to fix some specific stuttering issue in plasma wayland, but maybe introduced some other regression.

Interesting. Are you using the open kernel modules?
