Hi Damian (I have just loaded down the latest versions of activesky and Fs Sky.I am auto installing FsSky now according to there manual Quote Auto install will work on all 3rd party generators etc.It then goes on to say quote You should set your time setting little less than the update from the 3rd party weather generator.Ie auto install set to 5mins and the third party generator to 6mins(weather update). I am not queit sure do i have to go into options and what section do i have to compare.Do you have some thoughts on this matter as to what would be an overall effiencient setting. Regards Robin Stevens

Robin,The "most effiencient" setting is auto install=off. If you want different sets of cloud textures loading during your flight then your METAR Update Interval and FD/Export Update Interval should be set to a time greater than the time you have set in Sky World. Low times may lead to a great deal of system stuttering due to cloud textures being constantly loaded and re-written and the downloading and processing of weather data.Hope this helps,JimActiveSky Support
