Ok I am using the animations mod from the official 7th heaven library, so download it, install it, activate it.
then make sure its correctly ordered, so its after field models and before battle models.
Select configure, and there is an option for "60 FPS Battles" I have it set to on and its how I am doing it.
The only glitch I am aware off is summon animations get a bit glitchy and thats it. Its only a minor effect.
Ochu trainer should also work, but obviously thats not a set and forget it method.
