Could you explain how?

Gabe Newell put an end to that

So you are saying it's a bad analogy because DirectX has wider compatibility than Metal?

I'm not sure if I would put it exactly like that, but yeah, I am referring to Wine/Proton.

Also, see pjmlp's comments. Everything he said is spot on.

Could you please communicate instead of just replying? I have no idea what you're talking about and would appreciate a fully expressed thought instead of a one liner or a vague 6 word phrase.

No thank you. Good luck out there.
