Considering Stadia is Linux, make port for actual Linux / SteamOS

This is a redundant request, Cyberpunk 2077 will work natively on Steamdeck already.

Cyberpunk 2077 should work directly from your Steam library but they also advertise that you can install 3rd party games -- so it should be possible to get even the GOG version working directly. Basically, whatever you can run via Proton should run.

They do advertise that games on Steam will have the level of support for Steam Deck. Verified, playable, unsupported and unknown.

But of course there's very limited information at the moment. It should start to ship sometime after 25th and perhaps then we get more information when the reviews start to come in.

Thank you for the info. This is really great to hear, but where is this explicitly stated? You know, this is something that bothers me every time someone recommends adding non-steam games to Steam and simply force them to run with Proton (on a sidenote, up to this day I have NOT managed to get Steam to run the GOG version of Cyberpunk using Proton, but this is probably just my botched system).

To elaborate what I mean, I have heard numerous conflicting opinions in forums, about how much sense it makes to use Proton for non-steam games. If I understood it correctly, Steam does so much more that just run an EXE-file with the Proton runner, but it also involves a lot of tweaking, customization, configuration, inbuilt patches, you name it. All of this is not available when you select an EXE file, that Steam knows nothing about.

Honestly, I'm not an expert on this topic, but I would like to cite a reddit post about this issue: Source:

So, maybe I'm wrong, but to me this sounds like Proton is (of course) an option for non-steam games, though it is NOT recommended, as there is no benefit and it could also cause problems, that you would otherwise not have with native Steam games.

Does anyone have more insight regarding this topic? I'd really appreciate someone explaining this to me, since everyone seems to have a totally different opinion on this.

That looks like you can only use Proton and not the base Wine. That is odd since in Steam on Linux you can install multiple versions of Proton and Wine. But if ProtonDB is correct, that should not be an issue:

I think the biggest issue is if the hardware can run it. After 2 weeks when they start shipping we will probably find out.

There's already review versions out there but I am not sure if these are the final versions of the hardware. Seems like Cyberpunk 2077 at least launches on Steam Deck:

That's just the intro so it tells us nothing about how the actual gameplay runs.

And apparently high settings you can get 20+ fps and if you lower the quality you can get 60 fps:

But as Steam Deck is not out yet and these are review Decks I would reserve final judgement until after normal customers have received the product.
