In 2010 a 10 ms delay was added to every kGetEvent call to prevent
maxing out the CPU when some games display message boxes:
b0b4ddcc52
This rapid kGetEvent polling is called fast cast and it only exists in
SCI1.1 games and some SCI1 games. It occurs in an inner loop when the
fast cast global is set.
Now the workaround is only applied to fast cast games and only when the
kGetEvent polling occurs.
Removing this 10 ms delay from every SCI16 game cycle doesn't change
game speed by itself because the larger dynamic throttling in
kGameIsRestarting has been absorbing the 10 ms. But this does make the
other throttles easier to understand and work with, and solves minor
edge cases where delays from multiple kGetEvent calls add up.
