Confused on Steam Play and Proton? Be sure to check out our guide.

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: 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?

They tell you: They're getting a free controller + chromecast ultra with the purchase.

I too have pre ordered this game on Stadia as I'd honestly rather play an actual Linux build. Plus it's not like we knew it would work in proton DAY 0. I applaud Valve's effort but seeing as I haven't been able to grab a 6900XT yet it would be awhile before I could play this game the way I wanted to locally, therefore: Stadia.

Proton, Steam Play?! GG :D
Pay $60 and you will got $10 product because no RTX, no DLSS, no perfect performance, Proton just runs that game with low FPS and also no one knows how many times that low FPS goes to 0 when game will be updated.
Damn! Absofuckinlutely smart marketing from CD Project.
I'm not dumb to buy that sh*t. Yes, sh*t, because you are paying same as Windows users and getting maximum 25% quality compared Windows users.

1 and a half hours till release can't wait... thanks to all the AMD devs and Valve Mesa devs Pierre-Loup Griffais, Marek Olsak, Pierre-Eric Pelloux-Prayer, Samuel Pitoiset, and the DXVK developers

I think performance will be OK. I don't care about DLSS (I think it's an anti-feature in this case, I'd rather have lower resolution with better quality). Ray tracing isn't a big deal too, but it will eventually become usable. That's WIP now for both Mesa and vkd3d-proton.

I wonder what settings I will get to use with Cyberpunk. All I need is 4K 30FPS for chill couch gaming.

But DX12 to Vulkan is still beta, so I guess that is too much to ask at this time. But who knows!

But this is damn amazing. Good job Valve!

First time for a long time I would prefer to use a AMD graphic card.
I will wait for NVidia support.
Anyway it's an incredible news some Linux gamers could play a AAA games at his official sell date.

You're pulling way too many random numbers out of your ass for something that can't even be benchmarked right now.

Care to elaborate on how you came up with these? Otherwise please shove them back where they came from and wait for the release.

It's almost as if Proton has been working almost perfectly performance-wise for mostly everything that isn't blocked due to anti-cheat.

On a side note, this probably means Cyberpunk (Windows) won't be coming out with a Vulkan renderer either even though it's already working with it on Stadia... What a huge shame.
