Running Steam games on the correct dGPU with DRI_PRIME environment variable (feddit.de)

I added the following to the launch options in Steam:

DRI_PRIME=0 DXVK_ASYNC=1 gamemoderun %command%

ID 0 is my dedicated GPU (displayed as AMD Radeon RX 7800 XT), ID 1 my internal GPU (just displayed as AMD Radeon Graphics; it's in an AMD Ryzen 7 7800X3D).

However, the game (in this case Satisfactory, an Unreal Engine 5 game) still runs on GPU 1, the iGPU. Even when I edit the Steam .desktop launcher file to run the command like this:

Environment variables: DRI_PRIME=0
Executable: /usr/bin/steam-native
Arguments: %U

It still gets started on the wrong GPU with obviously abysmal performance. How do I fix this?

When I run it with the following Steam launch options:

DRI_PRIME=0 DXVK_FILTER_DEVICE_NAME=7800 DXVK_ASYNC=1 gamemoderun %command%

Satisfactory seems to somewhat reliably get the correct GPU, but not 100% of the time. The filter part I had to get from DRI_PRIME=0 vulkaninfo | grep "deviceName". You can apparently also use DXVK_FILTER_DEVICE_NAME="AMD Radeon RX".
