Alright, ever since I got this new computer, I have had an issue with stick spiking. At first, I just thought I had a crappy stick, because just as I got the new computer, my 2nd Saitek X-45 broke, and I had to downgrade to an ST-290. However, in December, I bought myself a brand new X-52 Pro hoping that would be a little less spiky, but nothing. It seems on both computers I have (Both being new, and not the old one I used with my X-45) there is some spiking, but my slightly higher-end PC with the video card seems to spike more than my other no-video-card-PC. Its not a LOT of spiking, but it seems like my plane snaps into a stall when I am being very smooth on the stick. It seems as if Im flying the plane JUST right with my input on the stick, but the stick itself amplifies anything I do in its input and snaps her into a stall. Its only my Y-axis I have issues with, and when in a neutral position, looking at the Map Controller window in AH, the last 2 digits on the Y-axis flash between 30-something and 90-something too fast for me to read either number. I have tried scaling, I have moved deadband and damping all the way to the top, and nothing stops that flutter, and all the increased deadband and damping do is make my plane react more slowly before the over-control and stall.
One suggestion was that I get a powered USB port, something I plug into an AC Adapter so the X-52 isn't drawing too much power, or spiking due to loss of power. Would this help at all?
