I found the problems, the kernel is to new for Nvidia, as I tried another os I encountered the same issue so I tried an lts kernel and all dx12 games launched

[massatt212]

if you use nvidia-open-dkms driver on linux 6.12 kernel dx12 and some other games wont boot, have to use normal nvidia-dkms in order for nvidia gaming to function on linux at this time, is it possible to fix this for us nvidia users?

[HikariKnight]

as with all issues caused by the nvidia driver, as long as the nvidia driver is closed source, only nvidia can fix their driver and there is nothing we can do to fix it.

[massatt212]

That's not the problem, the problem is nvidia-open-dkms driver not the nvidia-dkms driver the open kernel driver is the problem, if u change it to the regular driver it will be fixed, nobara has a fix let me find the link for you.

Rebase to it then? There is an Bazzite deck image with close nvidia module.

No game-mode though.

[massatt212]

i want the game-mode thats why i use bazzite lol

[Pryka]

I understand, but there is no solution here.

NVIDIA don't support it on closed module, there a bunch of stuff missing from there from my understanding.

There is nothing that Bazzite can do to fix this. Game-mode is broken on close module.

[massatt212]

They can fix it, the problem is not the Nvidia driver its the Open GPU Kernel Module from https://github.com/NVIDIA/open-gpu-kernel-modules the nvidia driver is working normal, the kernel modded driver is the problem.

So if they swap to the normal driver the problem is solved, or give us an option we can swap between them.

[Pryka]

I'm telling you that game-mode will not work properly on closed NVIDIA module.

I know that.

OPEN KERNEL MODULE = game mode works fine.
CLOSED KERNEL MODULE = game mode does not work.

Switching to CLOSED NVIDIA MODULE will solve your DX12 games issue, but it will break GAME-MODE.

idk how different Bazzite is, but on Nobara and Cachyos CLOSED NVIDIA MODULE works with GAME-MODE, im currently using it on 570 driver.

DX12 games work fine on the open driver, that's not the issue here. We do not ship a gamemode image with the proprietary driver and will not waste our time doing that since it's going away. Please open a new issue without all this off topic spam and a log of a game crashing via PROTON_LOG=1 so we can figure out why DX12 is broken for you.
