Spook's post in simulation rate was marked as the answerFrom Manual :
Time Acceleration Limit:
Time Acceleration should be limited to
8x to ensure proper autopilot function.
Time Acceleration should be limited to 8x
to ensure proper fuel system function.
(The mathematical iterations required for damping
and control law become prohibitive for most desktop
machines when run at speeds at greater than 8x, so
we have not tuned the autopilot or fuel system for
operation at acceleration rates faster than 8x.)
