Did not encounter any problems so far. Framerate is stable without any adjustments.

Runs great at 90 fps from default settings. While the opening FMV plays, the ending FMV will not, but is skippable.
When resuming from sleep, audio may crackle and be unpleasant for a while, or until restart. This seems to happen at random, but infrequently.

Added https://github.com/TellowKrinkle/atelier-sync-fix/releases/tag/atelier-sophie-20231022 d3d11.dll & used winecfg to set d3d11=n,b
. This should cause atfix.ini to be created on first run allowing better AA etc to be configured.
Works very well except the videos don't play and are replaced a placeholder.
However, there seem to only be 3 of them though stored in Atelier Sophie DX/Data/Win32/Movie/
where they can be watched directly. 2 placeholders play around the start of the game, presumably "opening.wmv" & "teaser.wmv". I haven't seen the 3rd video "ending.wmv" but I have a hunch when it'll play.

No audio for opening anime
Running at 5fps on main menu, at 720p lowest settings

Ran without any hitch.

A really good experience on the deck, it even plays the opening FMV with no issues with the current default version of proton
No controller cursor, need to use the touch screen to get past the launcher
if you suspend while playing, when you come back the audio will have crackling. Relaunching the game fixes it.
No need to use experimental or GE for the cutscenes anymore
Played through the entire main story on Proton 7.0-6 only to realize there's supposed to be opening, "title", and ending movies when I looked through the Extras menu. All 3 movies plays normally on Proton Experimental.
No other issues otherwise, both on default Proton 7.0-6 and Proton Experimental.
Capped TDP at 9-10w, and the refresh rate at 40Hz.
The game starts with a mouse-based launcher that cannot be disabled. You're forced to smear your screen with your fingers every time the game launches.
The opening FMV does not render (though the game will gracefully skip these). Solved by switching to Proton Experimental.
The game ran almost as well on the Deck as on my desktop, and even managed to render the opening FMV correctly with Proton Experimental, which was not the case on the desktop. An excellent game to play on your Deck!
Despite being an overal bad PC port, this game runs very well under Proton. Aside from the issue with the opening FMV, it runs very well.
Despite switching to proton-experimental, which supports rendering the opening FMV sequence, it was displayed incorrectly with tons of graphical artifacts and distorted colors. No fix found.
The game works perfectly except the videos, which require Proton Experimental or they won't play. The game skips the videos with no problem.
The launcher doesn't have controller support. It's simple enough to hold the Steam button and use the right touchpad to click the launch button.
The game works near perfectly with default settings. Normal players might not even notice the missing videos.
Opening video does not play without switching to GE
If you want to watch the opening animation just play it on youtube, at least until GE fixes audio. Otherwise works perfect on default.
Changing the graphic settings in the launcher via the touch screen can be a bit of a pain, but you really don't have to change anything in there.

The opening movie does not have audio played
Without using GE Proton, the anime video get skipped
Voice sound is a bit small, but if I try earphone, voice became normal. I am not sure if it is my system's issue or the game issue.
Runs fine. No need for dxvk.conf
or other additional settings. Even I forgot to configure prime-run %command%
, the game runs on nvidia gpu, why?
ran perfectly without me needing to do any extra work such as messing with a dxvk.conf file like others mention
The usual dxvk.conf with "d3d9.deferSurfaceCreation = True" for Atelier games is needed.
Like other Atelier games, this one will start into a white screen; to fix it you need to create a dxvk.conf file in the game's installation directory with "d3d9.deferSurfaceCreation = True" in it.
