Elite Dangerous initially uses dGPU, but then tries to use iGPU, preventing the game from launching

[BOTFerris]

Please describe your issue as accurately as possible.

When launching the game (via Heroic), the game simply does not open. Using environment variable "VK_ICD_FILENAMES = /usr/lib/x86_64-linux-gnu/GL/vulkan/icd.d/nvidia_icd.json" or "DXVK_FILTER_DEVICE_NAME=NVIDIA". This is due to DXVK initially using the dGPU, but then (as directly quoted by CommandMC, A contributor to Heroic.) "then for some reason the application creates another device (if that's the right term) and that for some reason uses your iGPU". The variables simply filters the "devices" to only use the dGPU, but that should happen automatically.

Just to make a small clarification. Dxvk just orders the list of GPUs presented to the game so that the dGPU is the first one listed, but a game can choose to use another one if it wants to.
