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.

Quoting: TheRiddickThe game for me came in 3 downloads.

59GB initial download
9GB Patch 1
250GB patch 2

I wouldn't call it massive, not when COD 250GB download exist!

Well, I compare it to The Witcher 3. I don't have COD :)

Also, was that a typo? You wrote 250 GB patch...

Quoting: Avehicle7887I'm probably one of the few people not excited for this game. All thanks to those skins that require galaxy to activate (My Rewards items).

Otherwise I could forgive painfully playing this game on my 5500XT until I get rid of Nvidia in favor of the 6800XT.

There is Galaxy exclusive content in it? That's rather annoying and I don't plan to use Galaxy.

Looks like I'm also going to be testing it on 5700XT, until Sapphire Pulse 6800XT will be sold anywhere.

So, as I understand, we need Mesa 21.0-dev for it? Any easy way to get it? PPA or something?

(Tried to start the game with Mesa 20.3.0 - it starts, but has heavy graphical bugs).

Edit: By the way, it's 64171 Mb in Steam.

You need Mesa master, yes. I.e. latest git dev branch. Some distros package Mesa master some have third party repos. You can also build it yourself.

Here is what I use on Debian testing to build it for example. The intention is to use it without replacing system Mesa packages, with any needed game on demand.

well damn, it looks like I won't be playing it at launch then... :-( I was really hoping it would have worked on WINE/Proton regardless of GPU ... I hope eventually Nvidia drivers get updated so this will play

I suppose I could get the PS4 version, but FPSes really demand mouse+keyboard for me

That's weird, because installer alone is 104 GB for me. Trying to install it in Wine now.

Quoting: Wernergreat news, but i ordered it on stadia, since finally it started in my country, i wanted to test it anyway and because they make a nice gift, if you buy Cyberpunk, you will get the Stadia Premiere Edition for free, so the game is free :). If the game is really that good then i will buy it later when all bugs are fixed and all dlc are released on Gog :).

Hmm why not buying on Steam? I mean, who made it possible to play it on Linux?

Stadia version is using Wine? Didnt CDPR ported to Stadia
