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.

Cyberpunk 2077\bin\x64
1.Rename Cyberpunk2077.exe to Cyberpunk2077.exe.bak
2. Use a hex editor on the Cyberpunk2077.exe.
3. Replace "75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08" with "EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08".
4. Replace "55 48 81 ec a0 00 00 00 0f 29 70 e8" with "c3 48 81 ec a0 00 00 00 0f 29 70 e8".
This turns the bad AVX call into a return and increase perfomance for AMD processors.
DISCLAIMER: May be breaking things under the hood, but seems stable.

Just to be clear - item #3 in that list is to enable hyperthreading in AMD processors. CDPR appears to have used an intel-biased compiler which forces AMD chips to only use a single thread of each core. It can remove your CPU bottleneck pretty significantly.

But since you're patching the primary executable, it'll be undone by any minor changes that CDPR make via Steam updates or GOG Galaxy. Pretty temporary upgrade! But by all accounts worth - reports between 15% and 30% increase in framerate on CPU-bound AMD systems which have beefy GPUs.

I tested that patch - no change, likely because it's already GPU bottlenecked. Also, I don't have any trouble with audio.

The common NPCs have voice? Not the history NPCs that you can interact and make questions, those are working for me, but the ones you find on the street and clubs, those are without voice for me.

A lot of them don't have voice. I assume it's because there are so many NPCs that they didn't have enough voice actors.

Hmm, I was able to test on windows and also saw a few gameplays and I could not find an NPC without a voice. Also, do you hear gunshots? what about music on radios and on clubs? for me I can hear some audio but not the music itself, is hard to explain, to be honest.

I didn't really test it extensively yet to notice that.

Not surprising. You have 3900x.

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.

I did not talk about stadia.
I am referring to:

"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"

And my question was: Why not on Steam? I mean, who made it possible to play it on Linux?
