I'm flying the a320, when I set the autopilot on ALT the plane moves up and down the selected altitude with a range of 2-3k feet. All failures and weather conditions are set on standard.

Do you have any idea on how to solve the problem? Thanks a lot

If the frame rate is low, the autopilot may have a hard time keeping up. You can often see this if you speed up time in the sim--after a while the autopilot will appear erratic because it cannot keep up with how quickly the information about the plane's movement and location are changing.

If you don't think that is the issue, please contact the aircraft developer directly.
