I use a cheapie joystick, a Logitec USB, but it does have 11 programmable keys + throttle so it works fairly well for FSX. Well, I have been using the Logitec Gaming Software to program the keys and then starting the FSX game executable thru the Logitec Gaming Software. I decided to just start the FSX executable and program the joystick keys directly in the FSX program (in the settings menu). Well, FSX runs MUCH smoother now.... most of the studdering during turns in the sim are gone. Just thought I would mention this as others may want to see if it is controller SW that may be causing some problemsFlt300ZPentium D 3.0Ghz1.5GB DDR2 MemoryATI X600 Graphics card19 Inch Dell FP Monitor

strange that's what got rid of your "studdering"...usually its an ugly mare that works the trick for that :-)..either way you may want to keep some toweling handy in the future incase it returns, LOLDave
