Runs perfectly except for controller rumble lag
Xbox Series X controller rumble acted weirdly, it was almost 30 secs behind what was actually happening in-game
Runs perfectly except for controller rumble lag
0 issues, game runs on high details with 100+ fps out of the box. I have also used dual sense controller with no issues.

lock to 45fps

Starts, shows some credits and that's it! Black screen and no progress after the credits scenses.
Just a piece of trash. Gave my money for nothing.

Perfectly fine, no thinkering, would honestly consider moving it to platinum

mangohud gamemoderun PULSE_LATENCY_MSEC=83 PIPEWIRE_LATENCY=1024/48000 %command%
Audio was crackling, poping and out of sync , but adding the launch command fixed all issues with audio for me, and decreased audio latency ...
PULSE_LATENCY_MSEC=83 PIPEWIRE_LATENCY=1024/48000
this fixed it for me !
Everything ran smooth .. fps was better than on windows for sure.. Audio issues are more a audio server thing , not much related to the game itself , but the command helped a lot with this ... Xbox login an everything works wonderful !

I had to manually delete all the Microsoft Visual C++ Redistributables using "protontricks". After uninstalling everything and launching the game, it works! Yipeeee!
The game did not launch on my linux PC without using "protontricks".

No issues, runs very well
Proton Hotfix
There is a black screen when starting the game, but when you press the super button and enter the game, it can be played without any problems.

gamemoderun %command%
First time fullscreening shows a black screen. After pressing super button and going back to game fullscreen initiated normally.
Turning off dynamic optimization in game settings seems to improve gaming experience a lot (less or almost non existent frame drops after turning it off).

gamemoderun gamescope -W 1920 -H 1080 -r 75 -f --force-grab-cursor --hdr-enabled -- env DXVK_HDR=1 %command%
Removed "TargetHardwareProfiler.dll" file
Game freezes frequently. Sound still plays, but everything else freezes, requiring a force close.
Minus the freezing, the game runs well.

Works almost perfectly, though the imperfections are likely not the fault of Proton
Tried playing with a gamepad and a Thrustmaster wheel (T300RS GT), both work as expected. Symbols on the gamepad are mapped correctly, however they are not mapped correctly on the Thrustmaster wheel (the keys are simply numbers).
After starting the game it launches in a windowed mode always, no idea if this is because of Proton or some Forza issue. Though this is a minor issue - you can always switch to full screen in a few seconds.
Also what can happen is that when I restart an event in game, the loading screen will go on forever. Though this is quite rare and I do not think this is the fault of Proton.

mangohud %command%
could be slower than windows

I was getting errors related to some missing DLLs that are provided by Microsoft Visual C++ Redistributables. I removed the ones already present and reinstalled using the ones directly from Microsoft. Latest Microsoft Visual C++ Redistributable Version.
The game would then launch properly.
Needed to Alt-Tab to get cursor within the window.
Controller could not be detected. Other games work fine. Tried with Steam Input as well and did not work.
Having to manually install dependencies seems to be a issue to both Windows and Linux. A few months ago this game worked perfectly without any tweaking. Not sure if it is regressions from Proton or Microsoft.
about 10 frames less comparing to win10 expirience, probably due to lack of proprietary nvidia drivers

Steam Cloud saves do not work at all
Steam Cloud saves do not work at all
Reinstalled the game, lost all progress

Mouse Inputs aren't detected(Keyboard works) but as long as you play with Controller it is as smooth as butter.
Not detecting Mouse Inputs
It's probably necessary to follow your OS` Controller/Gamepad setup to use one.

Can't get pass loading screen, crash or stuck at 100% cpu usage.
gamemoderun %command%
Used Proton Experimental to login in Xbox. Tried to play with Proton Experimental and 9.0-4, but it crash in the loading. Deleted "TargetHardwareProfiler.dll" from the game files, crashed in the same place. In Proton 8.0-5 got stuck in the loading with cpu at 100%.

gamemoderun %command%
A little crackling exists in-game.
If you move too fast, the textures sometimes can't load properly.
I'm using Hyprland, Mod + F combination didn't work and changing the fullscreen option on causes empty black screen.
You should swich to Proton Experimental, and run the game with "gamemoderun".

60fps lock in-game, 60hz in overlay, changed to High settings. Also might launch in the incorrect res unless you enable fullscreen (or toggle it on/off).
Xbox login first-time startup, also an oddity on launch is that the game has this introductory separate logo startup that sometimes just doesn't display (black screen with audio) but you still get into the game just fine.
Drops to 40fps area pretty frequently, especially if you're in the games faster cars and going 200-250mph through the map, LOD/pop in crisis on any settings (an issue with the game itself). Quite CPU heavy and thats why drops occur.
Nice bonus is that this one has proper 16:10 support. Little difficult on the small screen but totally playable.

gamemoderun %command%
sometimes get micro stuttering for 1 sec, no big deal

GE-Proton doesn't work, use Experimental. Besides that, the game runs with a few minor stutters, but the fps is generally higher than it was on Windows.

mangohud %command%
Online function cant be used properly since most of them need the xbox overlay from Windows
Pretty good, no bad comments to do about it.
mangohud %command%
If you are having trouble with a blank Xbox login window, try to run the game with Proton Experiemental and remove all launch arguments. Once logged in, you can switch back to whatever Proton version and add back all launch arguements.

Decent amount of texture bugs. Distant terrain turning white, vegetation turning all white/black, random objects having a purple tint. Nothing game-breaking though.
Signing in from desktop mode is impossible, but it works fine in game mode.

Runs fine, but...
Anti-aliasing and texture filtering don't seem to be working.
The game itself is perfectly playable, but anisotropic filtering and MSAA are broken.

gamemoderun %command%
After literally 4 hours (as per my Steam library) trying to run this game, now it works properly.
Besides switching to Proton 7.0.6 and using "gamemoderun %command%" as launch options, I needed the following tinker steps to work:
- switched my proprietary NVIDIA drivers from 535 (535.183.01-0ubuntu0.24.04.1) to 550 (550.120-0ubuntu0.24.04.1)
- Deleted "TargetHardwareProfiler.dll" from the game files, as indicated by other comments, to resolve the memory leak
Game now runs fine, occasional stuttering but nothings that impacts the experience too much. Can play online and with friends from my Xbox account.
Graphics performance may be 10% to 20% lower than native (win10/11)

gamescope -w 2560 -h 1440 -r 144 -f -e -- %command%
Really buggy windowing issues at least on my system (GNOME 47). Would not respect fullscreen option in settings, invisible start up logos while sound played, and sometimes I would be unable to tab back into the game unless I completely restarted. Using gamescope fixes these issues, just make sure to change the resolution and refresh rate to whatever your monitor supports.
Steam input and gamescope don't seem to work together (Xbox controller). Disabling fixes it.

runs perfectly out of the box, good framerate on high preset

12 TDP
There is a sign in for microsoft account, but this can be completed whilst launching from gaming mode
You have to sign into your microsoft account via the generic screen, then you are good to go.
You do not have to launch the game from desktop mode to be able to log in to the microsoft account.
I set TDP to 12W and set an FPS cap of 45.
Runs great on medium settings, 1200x800.
