Two bits of major news to cover for the Steam Play Proton compatibility layer, with some exciting major changes coming in with updates. Don't know what Steam Play Proton is? Go take a look at our dedicated page.

Firstly, if you have an AMD GPU and you don't mind grabbing the latest development code for the Mesa graphics drivers - Cyberpunk 2077 should actually work on Linux with the new Proton 5.13-4 release. Valve developer Pierre-Loup Griffais mentioned that CD PROJEKT RED allowed them some early testing time to get the work done for both vkd3d (the Direct3D 12 to Vulkan layer) and radv (the AMD Mesa Vulkan driver). As an NVIDIA GPU owner, this makes me quite jealous as it seems my only other current choice on Linux is Stadia or GeForce NOW (unofficially - until later in 2021).

Additionally, there's now also a new Proton Experimental branch available which has the start of major architectural changes to Wine. This brings with it a plan to reduce CPU overhead and improve performance in scenarios related to input and windowing. Seems Proton Experimental is an additional version of Proton, so you would install it along side the other versions currently available for this compatibility tool.

You can find the Proton changelog here.

The "Press space to continue" bug of Bioshock 2 Remastered seems to be FIXED in experimental Proton!!!

First off, any developer tries to make their game work on Linux through Proton is not against Linux. Regardless of how many people has wished for GOG Galaxy and Cyberpunk natively, you can't deny the market share. It's not enough to sustain native development of the scale that Cyberpunk is. This can't be stated enough. Proton is one of the biggest assets Linux has, besides quality native releases, to build market share.

On the subject of Proton and Stadia. I strongly believe Proton will always be the best choice if you care about gaming on Linux. Valve has poured so much into the ecosystem, and Cyberpunk being playable is yet another proof of that. You want native releases? Most if not all of Valve's games are natively available, including their big budget VR game Half Life: Alyx. And they haven't stopped improving Linux, their goal has been to make games as playable on Linux as on Windows. You may be buying a Windows game, but consider this..
  • Buying Cyberpunk gives money to decent if not infalable developers

  • These same developer are under GOG brand. GOG promotes DRM-Free gaming

  • Valve gets 30% cut. They are clearly spending money to improve Linux. So why wouldn't you buy on Steam

  • It counts as a Linux purchase when you play through Proton


Meanwhile, what has Google done as of late for Linux Gaming? Yes, Stadia is available on Linux but how can you be sure the reason it's on Linux is because their intentions are good? That they want to help Linux? I think they want to help themselves. Streaming does not seem like a difficult thing to provide for Linux. For any platform you need players for it to succeed. So it would be stupid of them to not support Linux.

Quoting: LungDragoQuestion - if I play Cyberpunk using a streaming service, can I transfer my save files once Nvidia gets its shit together?

Via Stadia: No

Via GeForce Now: Supposedly you're using your own Steam account, so you wouldn't even have to transfer, it'd be there.
(Nvidia just gives you access to a streamed windows device)

CD Projekt Red pushed crunch times for over a year now, and it ain't over, game is still full of bugs.
Devs may be decent, company is not. But I agree with all your other points.



EDIT:
Over a million concurrent peak players at launch, placing it top 4 most concurrent peak players on steam, within a few hours.
They clearly do not seek our money.

I think I know what's going on with installer size. It has all languages in it, while installed version has only the selected one, so it's smaller - just 60 GB for me. Or may be it's something else?

Quoting: Shmerlinstaller alone is 104 GB for me.

That is odd, not sure why its 104GB for you, pretty sure mines up to date, maybe what happened is you downloaded something extra?

By the way, not perfect but I managed to play a couple hours before a freeze on my Nvidia 1070 Ti.
The only annoying thing was the cracking audio, surprisingly not bothered by any shader compilation.
Let's hope the vulkan extension boost the perfs but at least it runs.

Testing in Wine-staging + vkd3d-proton master + Mesa master.

Intro video:





Character creation screen:



First in-game area (a bar):



Sometimes things glitch out in video sequences:



There are still some graphical glitches (like blinking black things and etc.). So things aren't perfect yet.

Nothing extra, straight download from GOG. It is weird that it's so huge while the game is 60 GB. May be it's languages like above.

The game is still too buggy to play for too long. Definitely some vkd3d-proton bug reporting to do there. But it's a good start!

I've read there was a 50gb patch, maybe you downloaded the game, they released the patch during download and you ended up needing to download another 50gb.

IMO vkd3d has a fair way to go when up against dxvk (dx11)

GOG provide static installers, and files are all the same version. Installed game is OK (60 GB), but 100 GB of the installer is puzzling. Unless they bundled the game and a patch in it, instead of just a patched game? That would be weird.

That's interesting. Updating the game with lgogdownloader using Galaxy protocol, shows that GOG standalone installer is behind the latest version. I'm going to re-test it.

Just to give an idea how it can be done:

lgogdownloader --galaxy-platform w --galaxy-delete-orphans --subdir-galaxy-install cyberpunk_2077 --galaxy-install 1423049311

Quoting: rustybroomhandleWondering what the specific missing features are in the Nvidia driver preventing this from working.

Amusingly, Assassin's Creed: Valhalla with vkd3d works on Nvidia but not AMD.

This extension is needed.

VK_VALVE_mutable_descriptor_type

Currently only implemented on RADV.

Any at least a ballpark ETA on when can we expect Nvidia to catch up? I haven't really been interested in playing a day 0 release before so I have no experience or data on this.

No ETA on that i'm afraid.

They did all the work to make a native version of the scale of Cyberpunk 2077 already: they developed it for Debian using Vulkan. They just won't sell it to us.

CDPR's involvement in "making it work on Linux through Proton" was bunging Valve a beta key, which cost them literally nothing. Valve wrote an extension for Vulkan to make it work, Valve contributed to Mesa to make it work, Valve hired developers to work on Proton to make it work; CDPR did absolutely nothing.

Developers should be rewarded for their support of Linux gaming, but CDPR haven't given any. Quite the opposite, in fact.

Quoting: WorMzyI'll wait for a native port. If the devs don't support Linux, then I don't support the devs.

Definitly you are right. But if the devs are working on a bit of linux (and or compability tools) isnt it worth to support them?
actually we would do great if we find a way to show them we are interested their games. maybe a linux gaming market bla bla or some statistics about how many games played under linux how many times bla bla.
so the companies can see and calculate aprox income if they release their products for linux too.
Nevermind. i will wait until Vulkan renderer implements. and will try my nv gpu.
Sundragon Dec 10, 2020
Well damn. I bought a new SSD and installed Windows to it specifically to play this. Oh well, more SSD space certainly can't be a bad thing!

Now I kinda wish I bought it on Steam cause holy shit, good job Valve.

And of course got a GPU hang trying to lower graphics settings.

Quoting: Linuxwarperany developer tries to make their game work on Linux through Proton is not against Linux.

Let's not give undue credit; unless I am missing something, all that the developers did in this instance was make the game available to Valve in advance - which they also do for press reviewers and such. That doesn't sound like effort to me.

It's working on NVIDIA!
