Valve hired him to work on it full time, then they released Proton (Wine + DXVK) a few months later. Proton likely would never have existed if it weren't for DXVK, and by extension the Steam Deck either wouldn't exist or would use Windows instead, and all the other cool Linux-related stuff Valve have worked on since probably wouldn't have happened.
Desktop Linux's marketshare rising is obviously not exclusively because of the gaming improvements, but it's for sure a huge boon. Good enough for a dumb meme like this, lol
I think Valve would have gone ahead without DXVK as well. Either with Gallium Nine or Wine's Direct3D implementation or so. With the Steam Machines they were already on the Linux train before DXVK.
that's true but i think compared to most other consoles nowadays it goes a very sustainable path. valve does nothing to prevent you from running gog games, which are true digital ownership at least. i know physical media are the most tangible option in the moment, but in the long run blurays for example actually have a limited lifespan
Steam hasn't (afaik) revoked access from a game that someone already owns, and DRM on steam is entirely optional, even if you use the steamworks sdk. (source: I am a developer making a game using the steamworks sdk that can run without steam open or installed)
most of the time i play switch and ps5, which i can get physical copies though. i just like to have them given the way a lot of streaming companies have just pulled content without warning.
edit: also that brings us to another point; you used to be able to go in and buy boxed pc games in the store all the time
This + the monopoly steam has over PC gaming and thier unfair pricing practices. I know that Valve is universaly praised for their contribution to Linux, but don't forget these issues.
I'd argue that the problem with non-physical releases is mainly conservation, and software pirates seem to have that covered for PC releases.
Now if you wanna buy a game, DRM free is of course preferable. I buy as much as I can from gog, because I don't want to blindly trust any corporation, regardless of their past record. After all, valve is set up in a way that gives them all the leverage.
Steam funding a Linux-based gaming OS became inevitable as soon as Microsoft started selling games in the Microsoft store. The message was clear from that point: If you stay stuck to a single OS, they can always shut you down whenever they feel like it.
