Hi,#. Bing Hybrid - Yes this works fine in the 10.1.1 release in both the standard WPF map display and when using the accelerated display mode.#. KML in the accelerated display mode - Unfortunately we were not able to support KML in the accelerated display mode at the 10.1.1 release because it makes use of ElementLayers for rendering some of the more complex aspects. Support for KML in the accelerated display mode is on the roadmap for a future release (timescale TBC). For now, if working with KML, you should use the AcceleratedDisplayLayers group layer to render the majority of your layers and just add KML to the map outside this group.CheersMike
