Overlays performance

I use a Raspberry Pi 3, and noticed that overlays have become more of a performance hit over the years, to the point where some overlays I used to use just fine will no longer be usable due to making the games run slow, so I was wondering if any settings can be used to make them run fast? Things like Threaded Video help a little but still dont make things perfect. Or maybe the images must be done in a certain way to be less demanding?

If not settings or image edits/specs, is there any possibility of this feature being optimized?
