Hey Jim,I just installed ActiveSky and am very pleased. My concerns were definitely unwarranted concerning frame rates..negligible. The weather just LOOKS better across the board. I haven't ventured into Active Radar..not sure what it does at this point. I'll probably be back w/questions (after reading the manual, of course!).Thanks for a graet product!Mark
