Tweak of the Week

So here is an idea. Occasionally I will publish information on various “tweaks” to the product and what they do. A “Tweak of the week” if you will.   So let’s start with the mysterious sounding FIBER_FRAME_TIME_FRACTION.   There are page after page of google, I mean livesearch, hits on this term.
