Have you gotten any where with this? I need to remove the flicker as well. I have been doing some testing, it you use the pan or zoom in, zoom out mapactions- there have this nice fade transition to them. If you call pan, zoom in, zoom out from the map control (like in code), you get a whole map redraw. Exactly like the GPS. It seems to wipe the map and redraw. I am guessing that somehow I need to apply a transition to get rid of the flicker.

Not sure if this will help, but try using the IGraphicTracker interface to expose the objects and classes to put tracking objects on the tracking layer.
The problem I am having is, I am reading the serial port for gps data, but for some reason I am getting poor performance. If I understand the tracking layer, it gets updated automatically every second, however the map data I am display take quite some time to paint.

Unfortunately, I'm begining to wonder if Arc 10.0 is slooow.

I've got the same problem few days ago (map that flickers when using WPF controls). I finally found the solution: just set the "EnableNavigationAnimations" property on the MapControl to false.
