I use PNG effects overlay files over BGFX (yup) and I've noticed the considerable drop in performance, indeed.
Games running at 75% speed because of a minuscule PNG overlay ? Seriously ?
Turned out in my case it was a matter of wrong GPU used.
I have a computer that allows to switch between the weak intel iGPU, and a significantly better geForce, you know that 'optimus' thing.
Naturally it'll always automatically pick the wrong one, so I've forced MAME to use the geForce and everything was back to normal speeds, even a bit better in some games (cv1k for instance).
Seems you can't run BGFX on anything and get similarily good performance ratios in every circumstances; e.g. that intel igpu weakness with overlays.
