Thanks Baracus250, I tried the dev mode and indeed I am limited by the main thread like everyone else. Looks like it mentions DX11 in the corner.
The screenshot was in 2d, and in VR it displayed the same.
My Ryzen 5 3600 doesn’t seem to suffer from overloading - most probably it is not that fast - I could see an average of 70% load when using hardware monitor.
I’ll wait some more for MSFS improvements before considering a CPU upgrade.
