Low FPS why?

Does anyone know why even though my GPU and CPU are less than 100% my FPS is only 37?

Surely my GPU should be running at nearly 100% ?
It seems like a waste of resources if the system is t take full advantage of it. Hoping someone can advise what’s happening here.

And to make it even more strange when I turn down the render scale down to 75 from 100 I get even worse results. Surely the performance should be better with the render scale turned down?

‘Limited by MainThread’

Your CPU is only ~30% fully occupied, but at least one core is running at 100%. That’s the limiting factor.

As an experiment, turn down both your terrain LOD and object LOD and see what happens to your FPS counter.

It made no difference. I left my pc running in the FS2020 menu for a couple of hours, went back and the performer is even worse! This is without changing anything. All settings still the same, and aircraft still parked up in the same spot. But I’ve now lost 10fps l, it doesn’t make sense. I’ve even changed my settings to low end and I’m only getting 24fps. 10 lower than a couple of hours ago at ‘high end’ settings.

Why start a new post when these topics are already being discussed in these posts?

I’ve just seen that after I started this post. It appears that this issue has been going on for a while. Interesting that some people have installed VPN’s and seemed to have worked with no fps drop after a couple of hours.
