Integrated graphics performance is poor when hybrid driver is installed

[Scoobin]

EDIT: I’ve just tried the live image (open driver only) with X11 instead of Wayland and managed to get the poor performance. So it now looks as though it was Wayland providing the solution and X11 the problem. Now my question is, how to force Wayland on Hybrid graphics?

EDIT 2: OK I’ve managed to finally get the best of both worlds using this Guide: [HowTo] Use Wayland with proprietary NVIDIA drivers. Now, using Wayland I’ve got lovely smooth integrated graphics desktop performance to go with good Nvidia performance. It’s funny because I had followed that guide at least 10 times on my previous system and never managed to make it work.

Thanks for your help and responses cscs.

So those meaning video-linux just … as in amdgpu and nouveau … in which you must envoke DRI_PRIME=1 just like above, but the difference being that using that env var would result in nouveau.

Which I believe is different than what you are referring to here:

When the live image is booted only the video-linux is installed/running according Manjaro Settings, and the Gnome desktop performance on integrated graphics is superb (it’s loaded Wayland but I don’t believe that’s the sole reason for good performance based on past experience). What I’m trying to understand is:

why is integrated performance good only without the prescence of a hybrid/proprietary driver set-up?

With the Proprietary hybrid install, I don’t manually add the env var so it must be done automatically. it includes both drivers and I’m getting good 3d performance in games etc, but when I’m on the desktop, animations are sluggish. BTW I forgot to mention I have dual monitors and I’ve noticed this configuration takes a performance hit when there are 2+ screens connected.

Which might be referring to some software like ‘optimus-manager’ or ‘optimus-switch’ which provides a way to select ‘nvidia’ or ‘amd’ or ‘hybrid’. But you are mistaken. All hybrid means is that it works as already illustrated here: you can envoke PRIME. With the other options being only one gpu or the other with no ability to switch. Nothing is automatic. You would still need to use prime-run to engage the nvidia card in that mode.

Most of my games are run through Steam with Proton. Could it be that Steam is envoking the env var?
