Why google Earth is slow zoom or move problem?
yes what the others said is true make sure your RAM is at least 50% free because google earth uses a lot of memory, its what us tech geeks call a (memory intensive) application and u can always try seeing if your internet connection is the issue or try going to the run command and typing "msconfig" and "disable all" on the start-up tab and frees a lot of Virtual memory and paging file space up by doing that if i can be of any more assistance please let me know.
