Snapcraft works on all major distros and provides a very convenient way to package any application without having to target multiple distros: you chose one distro as a base and package all the required libraries into a neat package. It's basically containers for apps.

CD projekt please make sure it runs on proton or wine or playonlinux. Best would be a native client tho...

My guess is : No , at least not at launch maybe in the future who knows.

Adding to other responses about "no one single, let alone stable platform": Proton is a bad candidate for wide use. It will always be slow and buggy (comparing to native Linux apps!) because of the sheer amount of complexity involved in the layers that power it: going from winapi to linux system calls and from DX11/DX12 to Vulkan is not trivial.

And no, using Linux wouldn't make up for that (it's ridiculous to suggest it even). Linux has a benefit because it has less garbage involved by default. You can't make for it by piling up layers and layers of translation/complexity.

Cyberpunk 2077 looks like it will be a fun game. That aside, if it is Win(your)data only then it can be fun for the lemmings who use that OS. When I dumped Windows it was to stop using it. Aside from the windows only games that were in my library when I switched to Linux,I won't buy a game unless it has native Linux support. There are plenty more games that can occupy my time *cough* PFKM *cough*.

When I wrote unchanging, I didn't mean "at all", obviously, just the ABIs -- but I admit that could've been clearer. I didn't say anything about packaging, though -- that was all you.

Crossing fingers for a native Linux support, especially since i see Linux as a perfect OS for a Cyberpunk game.

On the contrary, Win10 is (unfortunately) the perfect OS. Technology out of your hands, giant faceless corporations in charge? Sounds pretty cyberpunk to me.

Our future isn't Star Trek, it's Snow Crash :(

The issue of many distros is largely solved now with packaging clients like Snapcraft ( https://snapcraft.io ), Flatpak ( https://flatpak.org ), and AppImage ( https://appimage.org ), all of which allow developers to package their software to be distro agnostic. Indeed, it would be a relatively simple matter to package the game in all three formats, allowing users to chose which package client they prefer.

There must be a unix version of this game sins it is on PS4 and PS4 for runs a fork of FreeBSD.
I just think they got money to not release to linux.

It isn't? So why is Google using it for it's Gaming Service Stadia instead of the WIndows?

So CD-Projekt has a native version for Linux, but doesn't want to release it for Linux directly. Shame on CD-Projekt once more!!!

There apparently exists an Assassin's Creed Odyssey version for Stadia which will never be released on Linux. If you thought Google and game companies care about Linux, you're wrong. They support Google because it's a huge company with a giant pile of cash which creates a proprietary prison with telemetry and data theft for games.
Long live WINE and Proton!

Luckily, at least some devs like Egosoft care about the superior Vulcan API and Linux. Reward them for their behaviour and maybe we'll be seeing more Linux games in the future. Google and many game studios are the exact opposite of the Linux philosophy.

I do not think that you can deduce from the release of Cyberpunk on Stadia that CDPR has a Linux version of Cyberpunk. It is more likely that Google itself is taking over the development of a version adapted to Stadia. Stadia uses well-defined hardware (almost like a console), which makes development much easier. In addition, google does not have to look at the economy, but rather tries to make advertising for her only moderately well-rated Stadia project.

Even if you were to get the Stadia version of Cyberpunk, it would not run on your system unless you wanted to play it in a Google data center. In addition, Stadia does not use Linux because it is great for games, but because Microsoft is one of there harshest competitors and they prefer to use free independent Linux.

Stadia might use well-defined hardware, but it's still running on a base OS of Linux, and still using Linux render pipelines - possibly even Vulkan for maximum performance. The only difference is that the video and audio outputs are going to another piece of software for compression and network transmission rather than to a local display and speakers.

I don't see any reason to believe that Google themselves have ported CP2077 to Linux themselves, rather that they supply some kind of middleware which the developers can use to make their own build. After all, Sony and MS don't take people's games and do the porting themselves to the PS4/Xbone.

So first, it makes a significant difference in the effort if you are porting to an operating system with a fixed hardware configuration or many hardware configurations.

Second, MS and Sony already have established consoles on the market, they do not have to offer big deals for customers. Google, however, is completely lacking. For Stadia, Google has just chosen Linux as the operating system and they did know that there are only rarely Linux versions of games. It is therefore very likely that Google itself owns a department for porting relevant games in order to be able to offer an interesting range of games for its future customers at the very beginning.

We are talking about Google, which can easily invest $ 200-300 million in a porting department. It would be much more expensive if Stadia fails.
