I'm looking for a means of getting some diagnostic data that (as far as I can tell) isn't possible with the profiler. I'm debugging startup time, and I'd like to profile everything that happens prior to _ready being called on any particular scene. Script parsing, preloads, etc. I looked around the settings and googled a bit to see if maybe there was a verbose debug setting somewhere that would get the startup process to just dump everything it's doing on me, but no dice.
I'm no stranger to recompiling from source if there's a build setting that would get me what I'm looking for.
