6600M Spectrum refresh rate lagging?

I see in the specifications that the spectrum display on the 6600M is "real time". Most understand this to be ~30fps. I have looked at you tube videos and the spectrum display seems to lag. Perhaps, there is a setting  that is off in videos i have seen?  I know that you can change the speed of the waterfall.  For spectrum processing comparison sake only, when i look at videos of the 7610 spectrum display it seems much more fluid than the 6600m. Perhaps someone has a better HD video of the spectrum display in action? Also, does having multiple slices open/ dual watch slow this down? (the Icom 7851 drops to 15fps in dual watch - crazy for a radio that cost 13K+).

    For the flex radio, one thing to remember is that averaging can be added to the spectrum display so it is not bouncing...i know i set that to average value about 5
    this is similar to what you would see for FT8 waterfall display
    flexradio still  updates the display at 30fps but signal is now the averaged values

    as far as i know it can be set also on the icom 7610 as well as 7300
    some where deep inside the menus
    most hams dont make that adjustment...

    this type of bouncy display to me is nothing but pure dazzle
    visually distracting...

    The pan display is really all about personal preference.

    If operating local, meaning I'm on the LAN close to the radio I tend to opt for
    FrameRate: 20 or more
    Averaging: 40-70.   

    I like the higher averaging because the display becomes less frenetic in my option.  I don't like the jittery looking displays like the 7300 has in some of its averaging modes.

    When I'm operating remote and over WAN, especially at my office with terrible internet, I turn the frame rate way down to like 10.  I then play with averaging until I get a pan that feels good.

    The waterfall can be used to see that there was a signal in a certain place.

    Again this is all personal preference but to see what the 6600 can do, on LAN set the frame rate to 30 and the averaging down to 1 or its lowest setting.  It's pretty darned fast.

    I am not sure how quickly the Maestro front panel can display the pan but I suspect it is similar to a reasonable computer running SSDR.
