[SOLVED] Native games cannot detect Nvidia GPU

Games that are native on Linux [for example Minecraft or Tomb Raider] cannot detect the Nvidia GPU when running on Hybrid graphics and run on Integrated, while games running through Proton actually do. How do I change this so all games detect my GPU on Hybrid?
I use Optimus Manager to switch, run a GTX 1050Ti and my processor is an Intel Core i5 8300-H. My drivers and packages are all up-to-date. I'm a bit new to Arch and didn't know where to post this so...

Use the prime-run command from the prime-run package to run your native applications. This has little to do with native vs proton, more to do with vulkan vs OGL device detection.

So it's an issue with the game, not my hardware? That's good to know, at least.

Re: [SOLVED] Native games cannot detect Nvidia GPU

Dxvk (the directx to vulkan translation layer) in use on proton has code to explicitly prefer a dedicated GPU if present. Since that translation layer is not present in native titles they'll mostly pick what they see first unless you use prime-run to enforce the respective checks going to the dedicated card.
