Minecraft Using wrong GPU but steam games dont

Hi, i have freshly installed arch linux with X11
I have a Lenovo Laptop with 2 GPUs:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]
01:00.0 VGA compatible controller: NVIDIA Corporation TU106M [GeForce RTX 2060 Mobile] (rev a1)

I added these two lines to the xinitrc all at the top:

xrandr --setprovideroutputsource modesetting NVIDIA-GO
xrandr --output eDP-1 --auto --primary

And i added 10-nvidia-drm-outputclass.conf in the xorg.conf.d:
Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "PrimaryGPU" "yes"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"
EndSection

i get nvidia outputs like from nvidia-smi and when i start games from steam i can see in nvidia-settings that it gets hotter and requires more power.
But when i start Minecraft this isnt the case and when i press F3 i can see it uses the intel gpu.

here the intel driver:
glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa Intel(R) UHD Graphics 630 (CFL GT2)
