Valve's Proton Has Enabled 7000 Windows Games on Linux

Proton is Wine + DXVK + d9VK + custom patches.

The 'secret sauce' is actually 'Steam Play' which is the automated wrapping, configuration and execution of Proton wrapped games without the user having to do anything (other than a confirmation box to confirm that a compatibility layer is being used).

The Steam Play component turns it from a 'nice meta-distribution for wine' into 'killer quality of life improvement'.

How much of this is open source? I'd expect everything, including the per-game details?

(Not asking you to do research on demand, just in case you already know...)

Not sure about the per-game config, but the Proton is definitely open source [0], as are DXVK [1] and D9VK [2].

Steam Play is part of the Steam client, so is proprietary. ProtonDB isn't open source but does data dumps to github regularly [3].

Thanks!

I guess it somehow makes sense for Valve to keep the per-game tweaks private. With all of that money they're printing though, I sure wish they could feel that they could afford to be less defensive.

None of it is private. The per-game settings are all listed here, the options are all implemented in Proton, which is completely open source: https://steamdb.info/app/891390/info/

That's very nice.

I think this will make game preservation easier in the near future.

If it helps, Lutris has config for most games that are open source and available.
