Unable to select proper GPU

[StuffOfSonny]

Minecraft keeps running with my GTX960 instead of my RTX2070 and I can't figure out how to point it at the correct graphics card.

[Quantum39]

use nvidia control panel or settings to select minecraft (minecraft is javaw.exe) to use the 2070 by default

[StuffOfSonny]

Ah, my mistake, I forgot to mention I run Linux.
Garuda, with the official NVIDIA drivers. (it's arch BTW).

I'm curious on how that works, like how do you render your game on another gpu then the one your monitor is plugged into

Dunno, but that is what is currently happening.
The game launches on my Primary Monitor which is plugged into my RTX2070, but when I look at BTOP, it says GPU0 (my GTX960) is pegged at full use.

what does it say in the f3 screen
what does it say when you run nvidia-smi

[Quantum39]

seeing as your using linux, the solution after a quick search just seems to be installing nvidia-prime package and from there launching the program and selecting the correct gpu

[StuffOfSonny]

I apologize, as I have not needed to use nvidia-prime before, what would this look like? My guess is to edit the properties of the Prism Launcher .desktop entry to specify prime-run? Or will that only affect Prism Launcher?

[CrabbyDisk]

that sounds kinda cursed as a solution

[CrabbyDisk]

but I'm wondering what do you need that 960 for

[Quantum39]

minecraft runs with java, so you need to find where java program is located (should be somewhere in /usr/lib/jvm according to arch wiki. Note that this also means all java programs that use the gpu will select the 2070 instead) so minecraft runs with the correct gpu

selecting prism launcher will just make the launcher run with the 2070 instead of minecraft itself

[Quantum39]

i will try and test this out on a vm later to make sure

I run basic programs (browser, Discord, BTOP, OBS, etc) on the smaller card, and more demanding tasks (Games, Rendering, etc) on the bigger one.

Well one solution is to install a Java instance for Minecraft specifically (I typically grab Azul Zulu for use with this Faster Random).

Idk why but that feels kinda cursed and I think having the OS put the 2 outputs together would actually hurt performance, I wouldn't recommend doing that. 2 gpus could be useful for dual monitor setups but yeah, I don't think you should be using that.

I have 5 monitors.

4 on the GTX960 and 1 (4K) on the RTX2070.

quick question, are you on wayland or x11

x11

[CrabbyDisk]

you could try messing around in Nvidia X Server Settings, it seems like you can assign monitors to gpus in there, in the x server display configuration section

No idea what i'm doing, also I don't know why GPU 0 & 1 are swapped in this program.

idk try figure it out ig

in the process of trying to "figure it out", I somehow managed to make the nvidia-settings app kill redshift (or whatever equivalent is used in Plasma) on launch, but I could not get "PRIME settings" tab to show up. I'm gonna wait for @Quantum39's findings for now.

I decided to take a break from the headache and now Baldur's Gate 3 isn't rendering any graphics.
