This one is really necessary for new Atelier games... Without this, the performance is really bad. Just put the dll where the game location. In case the dll is not working, you just need to use the launch options I provide above (since it's optional for me. I didn't use it but it worked)

First of all, atelier-sync-fix is a must. It'll double up the framerate on the deck, since it's fixing something on the game. Without it, on the village, it'll only run on 30-35 fps and it's not a really god experience, trust me. And don't forget to set the shadow to low too on this game. The shadow is a performance hog, and for me, I can't see the difference on the shadow settings, so I just keep it at low for performance and it still looks good.

Playing it on 40 fps/40 Hz is better, since above that, the fps is not stable. This game can't reach 60 FPS, it'll lingering around 40 to 50 fps. So, the golden 40/40 is better and will be very smooth experiences.

I'm using Proton Experimental since the opening movie is not playing while I'm using proton stable (7.0-6). The game is run good with proton stable, but since the game just skipped the opening movie, I'm a bit afraid that the other movie that'll get played on this game will get skipped also.

And since I'm running 40 FPS, the movie feels a bit choppier (I guess the movie is locked at 60 FPS).
