Works for me with PROTON_NO_ESYNC=1

[guihkx]

Yes, of course! I totally forgot to try the game with PROTON_NO_ESYNC=1! Additionally, I also had to set PROTON_NO_FSYNC=1, because I'm using a custom kernel with FSYNC support.

Other than that, it runs pretty amazing. I get a constant 120 fps with no stuttering whatsoever, with the graphics maxed out. Here are the benchmark results:

Works beautifully with my DS4 gamepad too! But that's thanks to Steam, I think.

The only thing it doesn't work is online multiplayer, but that's expected since this game has GFWL integration and that's a defunct service.

It uses PulseEvent(); that's unfixable with esync.

So the game now works out of the box, I see.

Yup, it does. Proton now automatically disables esync/fsync for this title. I wonder if these game-specific workarounds are private because I couldn't find them in this repo...

[kisak-valve]

The runtime config options are being applied by Steam's whitelist config, even though this particular game is not currently whitelisted.

[guihkx]

So this list of workarounds is indeed private? Because I'll be opening a new issue for a different game that also uses PulseEvent() and it'd be awesome if Steam automatically disabled esync/fsync for that one too.
