Thanks for the link. I tried running that, but it seems to fail loading the noveau-driver (I have the proprietary Nvidia-drivers installed, as far as I know I don't have noveau installed). Does Godot in some way depend on using noveau, and can I install that alongside the proprietary drivers?
This is the output from running with index 0 (as you can see, I'm using a Flatpak build, if that would make a difference?). Index 1 did not use the Nvidia-card, but rather llmvpipe or something (I'm guessing CPU-emulated card?), and that was extremely slow.

The second block is after loading the project where it switches to Vulkan from OpenGL.
I'll try the on-demand thing mention in the same post tomorrow, I've yet to ever try running that instead of either dGPU completely on or off.
