Proton 4.2-2 still no luck.

Distro: Linux Mint 19.1 Tessa (64 bit)
GPU: Vega 56
Driver/LLVM version: Mesa 19.1.0-devel/9.0.0
Kernel version: 5.0.7-050007-generic
Proton version: 4.2-3

Game won't start, nothing happens Steam just says running for a while.

It's a DRM issue which is not supported by Proton.
It works with a cracked exe.

Any idea what DRM the game uses? I've tried searching but the only thing I can find is Steams DRM.

@kisak-valve Yes, it's CEG. It's in the nfo from the crack (Skidrow).

Looks like CEG (#753). There's a potential workaround by grabbing the game with Steam-for-Windows in wine and copying F.E.A.R. 3.exe over to the Steam-for-Linux install.

Is it possible for Valve to include that particular exe for Downloading the game with Steam-for-Linux? Why is that particular exe different in the first place, the game has no Linux version, shouldn't it be downloading the exact same files?

@KorinFlakes as far as I understand, the CEG DRM modifies the executable when launching the game, so it becomes unique to your system. So the problem is not that Steam downloads the wrong executable, it is the correct executable but the DRM is just not functioning correctly under Proton.

I'm halfway through the game, but now when I want to launch the game it crashes instantly.
Adding -d3d9 as a parameter fixes this issue.

Using a CEG-less version of the game and winetricks xact vcrun2008 mfc90 is necessary for the game to run (for some reason, mfc90 is not included when running vcrun2008).

Builtin xaudio2_7 currently causes the game to crash (https://github.com/FNA-XNA/FAudio/issues/242). This appears to be due to some kind of memory issue. Running it with SDL_AUDIODRIVER=alsa fixes the problem.

@kisak-valve this issue also affects the Windows version, hence why I've opened as a steam client issue because If there's a solution it may depends of a internal tweak (I don't know how cloud savings files are configured between developers and the client)

If (any) Windows game was never configured to use Steam Cloud properly, that's an issue for the game's devs to resolve. Hypothetically, you could try using Steam Support as an alternative method to give feedback for this game running on a Windows system. It's out-of-scope feedback for the Steam-for-Linux client and mildly less out-of-scope here.

I'm aware of it, and steam support only redirects to the original developer contact (which doesn't exists anymore). Anyway thank you for the feedback.

Tried without esync, fsync, with wined3d, without hiding nvidia gpu etc. no dice.

edit: Tried installing xact into the prefix also as i see Xaudio2 label here, but still no dice

I was able to get this to launch with only minor issues, detailed below, I will list the steps to prepare as if you already have the (nonworking) game installed:

1. Go to the tools section of steam, locate proton experimental, right click > properties > betas > bleeding-edge
2. Right click on Fear 3 > properties > Compatibility > force > proton experimental
3. Right click on Fear 3 > properties > local files >verify integrity of game files (It should say it needs to redownload some)
4. After download completes, play the game

Doing these steps I was able to launch and play the game. My first launch the game launched under my menu bar and file explorer, but this might be because I accidentally clicked away from the splash window while it was loading (shows a black rectangle for about 45 seconds before changing to a fear3 logo and launching fullscreen) Consecutive launches did not have this issue.

✅ - Game Launches Fullscreen
✅ - Video cutscenes play with no issues
✅ - Game is able to take input from controller and keyboard and lets you swap between
✅ - Rumble feature works on controller
✅ - No visible graphical issues, played for about an hour with no crashing or bugs
❌ - Was only able to display Keyboard + Mouse Glyphs, couldn't determine a way to show Controller Glyphs, either live-switching, only using controller after booting the game, or checking settings, was unable to determine if they were even available.
❌ - Can't remap buttons for controller, can only select between predetermined controller layouts.

Works with proton-experimental bleeding edge branch.

Consumes all the CPU when FSYNC is enabled. disabling it with PROTON_NO_FSYNC=1 fixes it, but the wineserver is still using quite a bit of CPU.

Seems to run pretty good.
