Hi Beppe. That is the point....many like it with avg and some without. It seems like an important function that is missing.
In your photo....you are right...it is not "too" bad with multiple panadapters displayed or the SSDR window shrunk in size. But with one panadapter displayed in a large size it is very very annoying. I don't always need to have multiple panadapters running and SSDR runs full screen on a 24" touch computer. Even when not a full screen I can't take the fast FPS. 20-25 FPS WITH averaging is perfect for me.
