STEAM_COMPAT_CONFIG="" %command%
Change wine to windows 7
I got the game working using the method above. However the game is not very well optimised for the deck; it kills the battery and has a subpar FPS for a racing game. I would not recommend picking the game up if you plan on playing on steam deck. It does run just not as good as you'd like for a racing game. I recommend DiRT Rally 2.0 on Steam Deck over this.

Compatibility tool ULWGL-Proton-8.0-5-3

Game automatically crashes without any tinkering; tinkering gets through first loading screen before game crashes
VK_INSTANCE_LAYERS="VK_LAYER_KHRONOS_validation" WINEDLLOVERRIDES="xinput1_3=n,b" PROTON_USE_WINED3D=1 PROTON_ENABLE_NVAPI=1 VKD3D_CONFIG=dxr,dxr11 %command%
Game could not make .ini file due to crashing too quickly; used the D3D12.dll and core (D3D12Core) files from Github
Using PROTON_USE_WINED3D=1 launch option seemed to 'void' the required DirectX Agility SDK

WINEDLLOVERRIDES="xinput1_3=n" %command%
I used my desktop to make a lowest settings config and moved it to the deck (/steamapps/compatdata/1953520/pfx/)
30 fps Limit
there are some small texts
Full System crash until I changed out the config ini
Online barely works and GE-Proton7-55 is the only version that gets online
Used the x64 dll from this github: https://github.com/ValveSoftware/Proton/issues/6288#issuecomment-1472551653
Steam OS 3.5 , GE-Proton 7-55 With Launch options: WINEDLLOVERRIDES="xinput1_3=n,b" %command%

WINEDLLOVERRIDES="xinput1_3=n,b" %command%
Trying the tricks listed below I found the following;
- Straight Install using GE8-11, Proton Experimental or Proton 8.0-3 without the command it crashes on start, no screens
- When using the Launch Command "WINEDLLOVERRIDES="xinput1_3=n,b" %command%" it will launch get past the launch screen but just before the menu it restarts the steamdeck
- Tried the command, using GE8-11 and the BETA developer channel as recommended by Cuppaccino below but that also restarts the steam deck after the NAICON screen, before the menu.

Single Player works, Leagues Daily Challenges work, Weekly stopped working with latest update.
WINEDLLOVERRIDES="xinput1_3=n,b" %command%
After last Beta channel update Weekly challenges stopped working. Stalls at sync with servers, Lobby and Leaderboards are working, but event cannot start. Daily challenges work. They stall at save after rally and Sync fails, but times and rankigs are saved so it works.
Only Weekly challenges are issue, but without them you cannot participate in Leagues properly.

WINEDLLOVERRIDES="xinput1_3=n,b" %command%
When system goes in sleep mode after some time sfns start working at 100% and I cannot resume, have to restart console. This happens when I am in the ingame menus.
Daily challenges in Leagues mode work as expected, I ama able to participate. Connection to servers takes some time, but otherwise works well.
Needs Experimental mode, otherwise works as expected, even multiplayer
the game crashes the deck after the intro at the start screen, main development updates needed to actually play it
WINEDLLOVERRIDES="xinput1_3=n,b" %command%
video and graphics options set to low, allow tearing activated, refresh rate set to 40Hz
short instructions to make wrc playable on the deck:
go to Settings -> System -> System Settings and enable developer mode
go to Settings -> Developer -> Miscellaneous and enable "Show Advanced Update Channels" (it's right above "Force Format SD Card")
now go to Settings -> System again and under Beta Participation -> OS Update Channel choose "Main" (you can also set the "Steam Client Update Channel" to "Steam Deck Beta", but it shouldn't really affect the performance and stability of WRC-G)
you should now be able to update your deck via "Software Updates". install the update (it will restart your deck and take some time, be patient)
after your SD rebooted, select WRC Generations, go to the cog symbol and choose preferences. then set the launch options: WINEDLLOVERRIDES="xinput1_3=n,b" %command%
last but not least: in the preferences menu, select "Compatibility", check "Force the use of a specific Steam Play compatibility tool" and then choose right below "Proton Experimental" ("GE-Proton 7-55" works as well)
this game seems to only run on the latest kernels, making it impossible to fully start up on a SD with the stable update channel
protontricks 1953520 win7
Is able to install, however immediately crashes on launch and displays "WRCG has stopped working." Forcing different versions of Proton hasn't fixed the problem.

Tested with Proton Experimental, 7, 6 and GE but it just crashes
