Valve Deckard Will Save Linux VR Gaming
Deckard will be a "standalone" VR device, suggests the leaks. And some articles about the leaks. Deckard being mobile/standalone like a Quest 3 presumably means it will , like the Quest 3, have its own operating system, which will presumably be a similar SteamOS Linux-based OS like we see with the Steam Deck.
That seems to suggest Valve will put development energy into making Linux VR in a similar state as flatscreen Linux when you use Proton, because they will need it to work as well for the Deckard as flatscreen gaming does on the Steam Deck, it seems safe to assume.
And now we have a major VR YouTuber basically hinting he may have reason to believe it's coming that he can't say at the moment...
