I see,
Thanks for reporting this issue.
There is some high potential that the issue might just be with the TY_FnHWaitForDialogue.js as the other two mods in your case don't really interact with TY_FnHWaitForDialogue.js in any way.
Just lately i was thinking of updating the mod to be more lightweight and also compatible with Termina.
But in this case performance seems to be the issue.
Could i ask you or any users of your mod to potentially identify where the FPS drops happen?
Is it in general or in special cases like the Yellow Mage trying to remove your limbs?
This would help a lot in building a more stable version for the mod.
Thank you!
