I don't believe in what i have seen. In my config redout demo has 10-30 FPS (Nvidia 750ti with 396.52 and ryzen5 1500+), and at some points It falls to 1fps. Can you verify your performance or the demo please?

finally i managed to find why for some people the game is unplayable.
the reason is that some distros (like ubuntu bionic) install only the 64bit version of libmpg123-0. the game codec works with the 32 bit, so wine activates a software decoding, slowing down the cpu.
the 32bit libs can be installed by terminal:

sudo apt install libmpg123-0:i386

then after restart framerate jumps from 1-10fps to 60-80fps on my system. wow!

@kisak-valve should i have to open a request for ubuntu on launchpad or for proton here?

Ubuntu 16.04, NVIDIA GTX 970, Proton 3.7-6 Beta:

Steam System Information

^ Unable to connect to online sessions
^^ Connecting Xbox 360 Controller overrides Steam Controller
^^^ Default graphics preset is Epic

NOTE: Testing excludes demo product (519880)

Fwiw:
The demo works, although it seems a lot choppier than the full game and the application bar of Gnome 3 pokes through.

The full game works perfectly, though I have not tested Network or VR.
No changes to default game config, no changes to Proton.

Tested with Proton 3.7-6 Beta

I get performance hiccups, especially in a career map in volcano area trial called "Blue & Red".
I tried various settings and tested them multiple times as performance varied at times until I could finally got to gold medal. In the end at most I got 0.5 seconds off between minimum and max graphics settings.
I didn't notice difference with nvapi fix from https://github.com/ValveSoftware/Proton/issues/1374 either.
Tested using Ubuntu 18.04, graphics driver NVIDIA 396.54 and Proton 3.7-6.

Well i've further investigated the problem as i could (not enough skilled to use apitrace). My very good performance happens if i don't select "effects". If they are set performance drops down a lot mailing It unplayable. Looking at GNOME task manager i've seen the game uses only my physical CPU cores, always at much less than full speed.memory usage is under 60% so the problem has to be the GPU. I noted that some circuits are extremely slow but their performance May vary by complexity. One thing stands clearly: in the few seconds at the start were veichles are waiting frames are already dropping. So it's not a problem of GPU load, probably, but i think more a problem of shaders cache. My suspect is that dxvk layer requires much more than 128mb shaders cache and the system hangs even when the scene is not moving for these reason.

Commented PROTON_USE_NVAPI from my proton user settings and performance issue went away...

Running the game in SteamVR mode with the Valve Index connected freezes my entire pc to the point of requiring a reboot.

i can confirm regression also for my configuration

@slavfox Do you still have this issue? It appears to work with Proton 5.13-2 and SteamVR 1.5.10 though there are a few visual quirks (e.g. incorrect menu position, flat planes obscuring left eye while loading levels)

On latest Proton (6.3-5) this game didn't load for me due to a weird Unread Engine 4 error: It was unable to find the "APEXFramework_x64.dll" from PhysX and gave a fatal error. I end up realizing it was due to filesystem case sensitivity, so I went to /mnt/data/Steam/steamapps/common/Redout/Engine/Binaries/ThirdParty/PhysX/Win64/VS2015 and mv ApexFramework_x64.dll APEXFramework_x64.dll, which fixed the problem and the game then worked flawlessly.

The same thing happened with the "GRIP: Combat Racing" game, which is based on the same version of the Unread Engine.

Hello, I'm getting this error when I try to run this game, I'm on Gentoo, which I'm probably missing some USE flags, but this is the only game so far I've tried.

The developer recently updated the game to a newer UE4 version and broke Proton compatibility. You can roll back to the older working version by going to the game's page clicking the gear icon then Properties->Betas and entering the beta access code "redoutvredition" without quotes.

Looks like the developer forgot to add the correct VC Redist dependency.

In the meanwhile, you can solve this by running protontricks -c 'wine ~/".steam/steam/steamapps/common/Steamworks Shared/_CommonRedist/vcredist/2019/VC_redist.x64.exe"' 517710.

(Do not use winetricks vcrun2019, it sucks.)

This game is listed as steam deck verified but just shows up a black screen.

Hdr doesn't work on the oled deck, I tried enabling it after starting the game in dx12 mode and it ends up just visually freezing the screen until you turn it off.
