Enlightenment Quest: Starbound.config!

Was wondering if anyone could detail some of the more obscure entries in Starbound's config file?

Some are fairly easy to understand, some don't concern me at all (online/multiplayer stuff), but the ones that are confusing.. Like bcryptRounds, checkAssetsDigest, claimFile, pixelRatioIdx, renderSleep/PreSleepRemainder, things like those.. Curious Generally looking for FPS/performance fixes (in that spoiler I've already disabled vsync and reduced maxFrameskip from 10 to 5, the rest should be defaults)..

Figure a clear explanation of some of these would be beneficial to the community :> Anyone know?!

 

I tried Google but no luck.
So bump it.

 

Bump-bump-BUMP! Apparently they're super secrets, because this thread drew no attention
