Preview mode can be especially slow when some frames have an animated ambient or animated transparency. Sometimes it applies the change at the wrong frame. This is even worse than a delay!

I'll definitely keep that in mind! Although i've yet to learn animated ambient. i've done transparency.... omg... that might be it... now i'm unsure how to fix it lol
