So I've beaten the main game,
here are some screenshots from the finish line. I used the
build 5479 because the most recent builds make the game freeze after a short amount of time. Used both Recompilers, Vulkan and limited the FPS to 30 for best results, rest of the options on default.
The game as a few glitches, mainly blurred skits (audio and video go out of sync), menu background doesn't seem to crop properly, there are black bars showing around character (mostly noticeable in cutscenes) and the game might freeze if you alt-tab for too long.
Outside battles, most of the game runs at a very good speed. In-game cutscenes' audio can be a bit grainy but nothing major. The game drop a few frames during loading times but you only notice it because of the audio lagging.
In battles, the speed is good. The main issue is that the speed is not stable and the emulator doesn't actually show the real FPS (it stays at 30 FPS pretty much all the time except for loading screens). Sometimes the combats will go a bit faster or a bit slower than normal, but only the video lags, not the sound so at least your ears don't bleed.
Overall it's a decent enough experience compared to playing on console.
