Fall Guys crashing even after installing EOS and enabling Proton EAC runtime (Solution: LD_PRELOAD needs to be set)

[TheDcoder]

Hi,

I'm trying to run Fall Guys on Linux with my DIY setup, I don't want to use Lutris or the Hero Launcher (bloated frontend for Legendary? no thanks).

I've had success with my setup until I tried to join a game, it promptly informed that Easy Anti-Cheat wasn't enabled. So I looked into it all and got it to enable with the custom GE wine build and the EAC runtime which was downloaded by Lutris (bonus points if someone can figure out where this can be downloaded without Lutris).

Launched the game and still didn't work, but found out that it was looking for the EOS overlay, so I ran the installation command and that fixed that issue!

But now I can't get past another annoying error: (output from wine)

FWindowsPlatform::TryGetValueFromRegistry: Failed to get value from registry with SubKeyName 'SOFTWARE\Epic Games\EOS\UserHelper' and ValueName 'Path'
FWindowsBootstrapper::TryGetUserHelperPath: Path does not exist in registry
FGenericBootstrapper::Bootstrap: Failed to find path to User Helper

It seems EOS was not installed properly and the game is trying to read the location of the "User Helper". So what went wrong? Legendary still thinks EOS is installed:

$ legendary eos-overlay --prefix $WINEPREFIX info
[cli] INFO: Using prefix "/mnt/data_partition/Storage/Arch Linux/Wine/.wine_proton_ge"

[cli] INFO: Overlay enabled: Yes
[cli] INFO: Enabled Overlay path: /mnt/data_partition/Storage/Arch Linux/Wine/Games/Epic Games/.overlay

How do I fix this? Can anyone who is able to run Fall Guys check what's in this registry key?

My config:

[0a2d9f6403244d12969e11da6713137b]

The overlay is not the issue, this is:

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct null not valid

Make sure to set LD_PRELOAD to some value before launching the game. The EAC runtime assumes it's set (since it is automatically set in Steam) and crashes if it isn't

Just one of those things found out by (& automatically fixed in) your friendly "bloated frontend for Legendary"

Ah, a laptop, fun stuff
How are you making sure the game is using your Nvidia GPU?

[TheDcoder]

By using some special env variables which make the OpenGL special sauce choose Nvidia. I also verified that the Nvidia GPU is being used by looking at DXVK's HUD feature :)

[CommandMC]

Hm, welp, got nothing then. Everything's working fine here

[TheDcoder]

Do you mind sharing your specs? Perhaps the slowdown is also due to the recent software mitigations that had to be done to protect against CPU exploits. Most "gaming" kernels have these disabled so maybe that's the reason I'm getting FPS drops. I will test this theory tomorrow.

[TheDcoder]

Turning off all mitigations with the kernel parameter mitigations=off did result in a very significant improvement in performance! I can play the game now, there are places where it still lags but it does not sustain for more than a second, often less than that.

One interesting observation I made are the fat lag spikes on the home screen for Fall Guys, not quite sure what's up with that.
