Anyone conducted research resulting in a formula (rough or otherwise) on the performance decrease that comes with layering something along the lines of this overly simplified MOCK formula:

AchievableFrameRate = [static hardware capability] / ( [data in frames] * [depth of layers] )

This is part of a long term project I'm working on-

If you're interested in research/development email me- I'll be testing this issue in the meantime and post my results here.
