Bad nvidia performance when using switcheroo to run glmark2 on intel graphics vs nvidia

English Install/Boot/Login
,
1

I got a score of 600 on glmark2 with command :
switcherooctl launch -g 0 glmark2
and 50 with command
switcherooctl launch -g 1 glmark2
But reinstalling suse-prime and rebooting with NVIDIA with the command
sudo prime-select boot nvidia
I got a score of 23551

That seems to be confirmed in the following thread :
archlinux


If you can't switch completely in BIOS/UEFI which should be preffered:

The simplest, ready made solution for most nvidia cards is installing nvidia-prime and using the prime-run command to start a game in question as described in: [https://wiki.archlinux.org/title/PRIME# … er_offload](https://wiki.archlinux.org/title/PRIME#PRIME_render_offload)

On GPUs/CPU combinations like yours that are a bit older, this will lead to not being able to fully suspend the nvidia card while not in which will have a higher power draw. If you want more control over this, other options are outlined in: https://wiki.archlinux.org/title/NVIDIA_Optimus -- note that none of the other options outlined here will generally give you better performance than the PRIME method, if performance is your main concern and you don't care about power draw you should stick with PRIME or disabling the iGPU completely.

What Hardware setup inxi -GSaz, what Desktop Environment, wayland or X11?

@jcdole no EGL or Vulkan? So can’t help much with you running X11 and suse-prime/bbswitch which is really designed for older optimus hardware.

With that hardware (both Intel and Nvidia) I would sure be using Prime Render Offload as well as a later version of Mesa (Slowroll or Tumbleweed).

To be honest, if what your using works, rock on and wait for Leap 16.0 and revisit along with using Wayland.

Likewise the Ultra’s (Arrow Lake-S) CPU/iGPU have so many features, hopefully you will get to take advantage of these.

To switch between GPU, I use :
for NVIDIA :
sudo switcherooctl launch -g 1
sudo reboot"

and
for INTEL
sudo switcherooctl launch -g 0
sudo reboot"

Nothing special is configured as it is a new install on a new laptop.

There is no reboot required. Additionally , there is no root or sudo required to run switcherooctl.
Switcherooctl does not permanently switch the use of a GPU. It works on a per application basis.

switcherooctl launch -g 1 will do nothing as the application is missing from the command.
switcherooctl launch -g 1 vlc will launch VLC using the device 1 (dedicated) GPU.

suse-prime and switcherooctl are completely different. suse-prime allowed to permanently use only one GPU after rebooting. switcherooctl uses a more granular concept as it allows the user to define which apps he wants to start with the dedicated GPU.
