[fritsch]

fps will be gone in the next rebuild :-) cause of exactly your question. This fps value never was anywhere accurate it is my shoesize + some nails + x. Therefore it will be removed in kodi v15 completely. Smoothness you can see at the skip / drop values.

The 175ms delay we measured some years ago while asking several 100 people about the delay AVRs add when processing 24p content, therefore we add this by default via advancedsettings.xml
