No, not exactly. In v21, they've made it so that way the game speed isn't dependent on the framerate like it use to be. However, EBDX still uses frame-by-frame animation for their move animations, battle entry, etc (since it was before v21). So when you play the game at like 150 fps, it becomes ridiculously fast.
So, I essentially just copy and paste the code for the tick system from the wait function already in essentials v21, did a few slight adjustments and well, it's now going at the normal speed even at such high fps.
Luka will probably come up with a different method cause it was a little not-so-great, but that's my temporary fix.
