 I'd like someone to explain how is it possible to write a RealTime
 application without a RealTime operating system ?

 As far as I know, but I am not a specialist on that, Windows 9x/NT does
 not provide any equivalent of locking a CPU or having non degradable
 realtime process priorities that prevent the system to take time over the
 application.

 Is it that the meaning of RealTime changes when we deal with PC ? Are
 final customers happy with uncontrolable frame drops ? Or is there other
 ways to ensure RealTime with NT ?
