Hello,First of all:Check if you have programs running in background...If YES .. stop all unnecessary programs and certainly those who are scanning files and folders at realtime (like antivirus and antimalwares)Test and see if this help !Regards.Gus.

Check if you have programs running in background...

Yup! That's the very best advice.Also, see about dedicating one core to FS9. That may help. I've recently added Air Hauler to my FS9 ensemble and now I get occasional stutters when running Air Hauler and Radar Contact through FSUIPC with FS9. It's worse with AI labels showing. I suspect if I had a quad-core instead of my ancient single socket-748 I could dedicate one to FS9, one to AH , one to RC and one to everything else with pretty good results.Ah, well I'm dreaming now. Cost is no object but I really can't face all the reinstallation...Regards,D
