Thanks for the reply! Not blaming you (you've done awesome job here!), just bringing up an interesting point and was hoping to get insight but apparently not so much :/
I hear you. FWIW I think they might be measuring how long the render takes and then showing the inverse of that as the FPS. If so, that would equate to a kind of theoretical maximum frame rate. The code is minimized though, and I didn't look very carefully.
