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.

Leopard 9 Dec, 2020
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.

Without it game will hang regularly.

This is the first time I've seen AMD ahead of Nvidia! The times are changing. Maybe next time I need to buy a GPU, it'll be AMD. What a world.

I don't think it's the first time. Vulkan transform feedback was in Mesa a bit before Nvidia too if I remember correctly (which made The Witcher 3 playable in Wine+dxvk).

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?

Honestly I was going to purchase an AMD GPU at this round, and I would have if I had found any in the stores.

By the time there will be back again a supply of AMD cards, CP2077 will be fully playable on Nvidia too.

Quoting: mylkagood to know, even if i cant buy 2077 now

i hope it works kinda decent on my old GPU

from what i saw of the benchmarks you need a pretty beefy gpu even in 1080p.most people are gonna be running in medium to high settings in 1080p.

thx. so i need money for a new GPU and the game

?
i have had few of their driver hangs in the past, but can't recall from recent times. (im using their vulkan betas most of the time) And i think nvidia drivers are pretty good at recovering after hang, so you dont get system hardlocks like with AMD... but iirc AMD is working on gpu recovery also, if its not already done.

anyway that's a bit offtopic for this
