how to fix the unable to initialize steam API
crack
Game works now with proton 5.0-2, slight audio cracking is present (pulseaudio + tsched=0).
The opening movie now works with the latest Proton GE 5.8 release.
Almost appears to work well with Proton 5.13-5, however theres an issue of extreme lag with esync off, or if I turn it on the game will somewhat randomly freeze during gameplay
[SteamDeck] God Eater: Resurrection issue | Soft Locking
Issue transferred from https://github.com/ValveSoftware/Proton/issues/6091.

Game is rated as steam verified for the deck, but the game suffers from soft locks for 10-20 seconds during mission select and will soft lock mid game during hunts.
The game will sometimes have issues with audio playing as well, but the soft locking is the biggest issue to playability.
Issue can be semi resolved by using PROTON_NO_ESYNC=1 %command%, but game suffers from performance issues after playing with the command on.
Same effect when using PROTON_NO_FSYNC=1 %command% and PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%
Additionally, The game is not available to list issues on ProtonDB, due to the game not being available on the store as it comes bundles with God Eater 2 Rage burst
Even as of today, with Proton 9 (Exp or GE), it seems like the game has to be run with either no Esync & no Fsync, or pinning the process to one core with taskset -c 0 to avoid pauses when accessing new game assets or elongated load times.
Additionally, I had to be sure to install the d3dx9_43 protontricks verb in the prefix to get the game to start and not crash when minimizing the window (which it does automatically in fullscreen when losing focus), and wmp11 for the FMVs to work (or else showed nothing after the logos when starting, and I would just have to press a button again to continue to the title).
Looks like the cutscenes finally work out-of-the-box as of Proton 10's beta. Disabling esync and fsync are still required for good loading times.
If using a fork of Proton with NTsync supported (as of right now, GE-Proton10-9 is the first version with this added), loading times are fully resolved when NTsync is enabled and doesn't require core locking anymore.
Anecdotally speaking, d3dx9_43 doesn't seem to require a manual install anymore, so the fullscreen suspending issue is fixed (at least on Wayland?).
@wantija Would you verify that the FMVs still work currently? For me, 10-1 beta, Experimental, and Hotfix all show testbars, and GE10-9 still shows a black screen and requires a manual wmp11 install.
Yep the intro video still works for me with Proton experimental and Proton 10.0 beta with fresh prefixes.
I've had no issues with the intro video on my side, just make sure you have shader precaching enabled and it should work fine.
Proton experimental bleeding edge has changes that help loading times for this game, remove any launch parameter that affect fsync and you should notice much faster loading times. Info about how to use bleeding edge https://github.com/ValveSoftware/Proton/wiki/Proton-Versions#proton-bleeding-edge
@simifor And for the people that don't want shader precaching enabled...? The storage overhead is too much for my home directory which is almost constantly short on space, and I've never had to enable precaching for any of my other games.
While, yes, this does work (though for me requires setting to Upstream Experimental rather than GE), if this is a requirement to get preconverted FMVs, this ideally really shouldn't be under shader precache and should be its own thing that can be downloaded alongside the game independent of this option; since as soon as I disable precache, all precache data goes away including the aforementioned videos and in comes back the testbars.
Hello @SeongGino, that request is being tracked at https://github.com/ValveSoftware/steam-for-linux/issues/9132.

Other thoughts
Game apparently used to work according to WineHQ: https://appdb.winehq.org/objectManager.php?sClass=version&iId=34449
The game does actually start in wine 3.18 staging, but crashes at initial loading screen.
Things I've tried that make no difference:
