Ok here's what I did that helped. I took off from the SE corner and flew to the NW. Just got up at 15K and walked away for 1 1/2 hours. Came back, relogged, smooth as silk!
Haven't tried it today, yet. Work. Sure seemed to help last night. There was 43 pilots on when I started this. I had been on long enough to download all skins. Seems I needed this extra time to smooth it out. I will up date this as I fly tonight.
Regards,
