thank you for answering eagl & skurj , i cant imagine that the reason is a other programm etc. also the framerate lock brings no result , i ride a p3 850 with a geforce2 card and i can say framerate is not a problem ....(ok , it drops down when i fly in big formations but i am sure this is normal).
now i have tryed to disable the joystick and flying with the mouse , and i realized no stutter effect , but when the reason is in the data stream from the joystick i am not sure what i can change there , i use newest driver for my ch f16 fighterstick.... i also tryed other joysticks with the same result. i think i need a tip from a ´good technican´....
my operating system is also 98se ....
i will fly today with mouse only and when i have no stutter effect again it -must- be something with the joystcik or joystick port etc.
greetings from germany
