Given a million years, I'd say the human race ending is more likely than the human race figuring out how to run Bloodborne 4 on a Steam Deck, given that in a couple years, Steam Deck 2 will outperform the original SD.

I'm confident humanity will get Bloodborne to run on the Steam Deck, before going extinct.

According to BossingAround, it's a close tie.

If it takes Ship of Theseusing your Steam Deck, it’s arguably not running on the Steam Deck.

Also downscaling and hand optimizing hot paths.
