just a small note…
Event processing faster than rendering is useful for some action games.
Some games update their simulation loop faster than the rendering loop.
It really can make a difference in how responsive the game feels.

Am wondering if anyone know a REAL-TIME drag & drop GUI SDL library? Not windows
event-based driven, but real-time driven. It’s for a game so there’s going to be
things updating while a drag is happening, etc.
Events are how programs get information on what is happening.
What’s referred to as “real-time”, is actually “sufficiently low
latency”, and not quite “zero latency”. In the case of a game, you
only need to process events fast and render the effected result within
a refresh cycle of your monitor, anything faster is just unnecessary.
What you need is to keep some state on whether a drag is going on or
not, what is being dragged, and so on. When a mouse motion event comes
in, and you have an object currently being dragged, you go an move it,
and so on…
