Newest version of ProtonGE fixes the intro audio. It is still recommended to use the atfix file located here: https://github.com/doitsujin/atelier-sync-fix/releases/tag/v0.5 Follow the instructions, and the game will run at 60 fps. In the launcher, I turned off bloom. It may help with increased performance, but usually the series has a really bad bloom quality, so it should graphically look better without it. All other settings left untouched.
audio of OP/DE videos are missing
On default Proton the op/ed videos won't play, so I suggest playing Atelier series >= A17 on Proton GE. Maybe the games < A17 has the same issues but I have not brought them......
No audio during movies with eggroll, no movies at all with default proton.
Weak framerate until a fix is applied
In order to make the game run at smooth 60fps apply this fix https://github.com/doitsujin/atelier-sync-fix/releases/tag/v0.5
Video plays but no sound is heard
If you use Proton provided by steam, the video won't play and get skipped
The game status is running but nothing shows up and yet the game didn't seem to crash
This game running stable and better than original version first attempt without issue at all.
Other than that needs the opening and ending to be play just like windows 10.
