|1= those systems are not "processes", but just "loops" - i.e. whatever the thing is called in the list, you should append "update-loop" to it - and some names are still misleading (events=Nasal). | |||

|1= FG is basically using cooperative multi-tasking-imagine it like a team of people (15+), all of whom need to finish their work and hand it over to the next person, so that a single frame can be produced - with some people (subsystems) being allowed to redo/check their work several times in a row (fdm, autopilot), while others will only get a single opportunity to update their internal state. | |||
Finally, it is this "team of people" that will produce a single frame - so whenever "someone" is too slow, it will end up causing stuttering. No matter the reason, scenery/terrain, Nasal etc - at some point, another subsystem will have to wait, which means fewer frames created per second. | |||
