Getting steam games to use hybrid nvidia gpu (nvidia-450xx)

So I have nvidia driver 450.66 installed. I have been trying to launch Doom, Deus Ex and more games, which didn’t work because I had launch options as prime-run %command% (for nvidia 440xx driver). So deleting that command launches games, but they run on cpu (no load detected using nvtop).

I have installed the 450 prime driver with the command sudo mhwd -i pci video-hybrid-intel-nvidia-450xx-prime
I have also done sudo mhwd -i pci video-modesetting.

Am I missing anything?

The threads I have seen so far talk about not being able to launch steam itself.
I have seen people using AMD graphics use special launch code, is that something I should look better into?

The prime-run command works with 450 drivers. The easiest option is to launch steam games with lutris, you can select prime offload, gamemode, resolution and much more in the launch options

Me too same problem, I have GPU GTX 1650 and ryzen 5 and manjaro auto installed auto installed video hybrid-amd-nvidia-450xx-prime but video encoding does not work in “Shotcut” program it fails in moment

Have you tried lutris to launch steam? See if toggling prime render off load works

Ok, I am going through the configure settings in lutris for steam. First I notice is Optimus launcher (Nvidia Optimus laptops) which is off and I have no other option.

Prime Render Offload is now enabled

Feral gamemode is enabled

Not seeing any changes but I haven’t rebooted yet. brb

The good thing about lutris is if you click the terminal button it will show you the log off what happened and if it fails why

Well nvtop is not showing any difference, but the gameplay is totally different. Even just the loading took almost 3x shorter time this time.
Thanks for the info.

Sorry, I spoke too soon.

Gameplay is much worse than on 440xx prime-run experience (same settings).

Don’t get me wrong, this is a huge step from using just the CPU (as last time), but input-lag and fps is way off.

I am linux noob which driver is best for amd-nvidia hybrid graphics driver??
hybrid-amd-nvidia-450xxprime one or nvidia-5450xx one?

I’m not an expert on amd/nvidia combo but I’m guessing it would be the same as this post

I am in UEFI how i will disable integrated GPU one ?

Any other settings I could check?
It seems like I am not implementing the gpu at all. Lot of smearing, input-lag and drop in fps (game renders like it’s very drunk) and nvtop shows no usage for the gpu.
Maybe I forgot some driver installation??
Settings for lutris
Resulution: keep current
render offload enabled
game mode enabled
use discrete graphics enabled
run terniman enabled (got no errors)
