How was Ys IX’s performance?

Been a long time since I finished the game, but from what I recall it's "definitely playable, but has issues".

Most areas including dungeons run fairly well with a stable framerante, but there's a lot of fluctuation when exploring the main "hub" which is this huge open-world city. Since you don't do a lot of fighting in the city this doesn't hurt gameplay too much, but it's definitely annoying.

But there are some "tower defense" stages similar to Ys 8, and and performance can tank hard there. It doesn't happen very often, and usually only lasts a few seconds, but it's another thing to keep in mind.

Hope they fix the sea exploration, but the game has been out in Japan for a while, so I doubt there would be any changes to gameplay now.

They probably expect you to stick to the main story for the early parts of the game and go exploring the map later, when you have enough boat upgrades to make it less frustrating... but my OCD doesn't let me progress without checking every corner of the map first. 😅
