Hmm, sadly, yes, since Factorio uses OpenGL as its graphic API, there's no way to request a device type like it's usually done with Vulkan. Then maybe a GPU can be selected based on its VRAM size?

So, the problem is quite simple. I have a dual GPU setup (an integrated GPU & a discrete GPU) and, by default, Factorio selects the iGPU regardless of the current graphic settings. It's not noticeable on the vanilla game but, with mods, the game squeezes everything out of the iGPU and runs at 1 FPS ...
