Doesn't seem to use dGPU on a dual GPU laptop

[Yogchan]

I have noticed that some games were more laggy than usual and after some digging I figured out that for some reason it's not utilizing the dGPU (it's an nvidia GPU). But when I try to run the same game with proton the dGPU is utilized.

system:

Distro: Linux Mint 22.3 - Cinnamon 64-bit
  dGPU: NVIDIA Corporation GA107M [GeForce RTX 3050 Mobile]
  iGPU:Radeon 680M

Here's the log when I run a game

ChatGPT wrote me this
On dual-GPU systems, you may need to use environment variables or driver-specific tools (like prime-run on Linux with NVIDIA Optimus) to force Chromium ( one of the libraries of nwjs ) to run on the discrete GPU.
prime-run rpgmaker-linux

I don't have an Nvidia card, so I can't check/fix the problem.

[Yogchan]

Sorry for the late reply. I had to reinstall my distro and am now using Arch.
I gather I should add prime-run to the desktop file the program creates for the game is that correct ?
if so I'm afraid it doesn't seem to fire up my nvidia gpu as well

[bakustarver]

You can add the following argument to the chromium-args section in package.json:

--force_high_performance_gpu

File path:
desktopapps/nwjs/nwjs/packagefiles/package.json

You can also open the following folder:

desktopapps/nwjs/nwjs/nwjs/nwjs-v0.108.0-linux-x64/

Then try launching NW.js using one of these commands:

optirun ./nw

or

prime-run ./nw

[Yogchan]

unfortunately both of these options didn't seem to trigger the discrete GPU to kick in.

I tried again on this new setup to open same game again in proton GE on steam to make sure it's not a gpu issue but opening it this way kicks in the nvidia gpu normally.

have you tried passing DRI_PRIME=1 through? worked for me with an Intel/AMD setup on my Laptop.
