Frame rate drops bad

[johnk51 2]

When I'm fling at cruise, I have frame rate set to 30.  Then out of the blue it will drop to below 7 fps and sometimes 0.5 fps. This last for 5-15 seconds.  Then back up to 30.  This usually happens in the eastern part of the USA.  The west coast and mid west hardly at all.  I'm usually flying my PMDG, or some of my bigger planes.  When it happens, I'm out in the middle of nowhere at 30000 +.  I have a Ryzen 7 2700, 32 gigs ram, a Nvidia 1060 video  card with 6 gigs, and windows 10 pro 64bit.  I'm using P3D v4.5 pro.  I don't know why the east coast has the most drops. I might try some of my small planes around the east coast to see if it's as bad as the larger ones.

Can you run the Windows Task Manager and monitor Performance while this is going on?

Things to look for:  Scenery loading episodes where all CPU cores are busy, or other Processes deciding to take over and bring the first P3D CPU core to its knees..

Hi John,

What's your AI set for and do you have a lot of plans installed? If you use a high % or 100% then loading AI can cause this (any AI at all causes a bump for me in the NYC area). Think about flying in to NYC from the southwest say from around KMEM. Going from south to north you have KIAD, KDCA, KBWI, KPHL, KEWR, KJFK, KLGA and KBOS to contend with. If you have 50-60% set for traffic by the time you're halfway between KPHL and KEWR you can easily have several hundred AI on the ground and in the air to contend with. Throw in the dense scenery around NYC and there's a lot happening with system resources.

Long winded way of suggesting you look at AI settings and try lowering them if you use high settings. Bert's suggestions are a great way to start IMHO.

Hope this gives you some ideas.
