I’ve been playing around a bit. If I uncap my system at 4K ultra I get between 55 and 60 fps, my GPU is is between 98 and 100 and my mainthread gets killed. I can’t get over 60 fps in 4K even with a 3090, 10850k which seems pants. This is looking around airports with the drone cam, I haven’t tried flying yet, I don;t know if that will be more or less demanding.
Interestingly by far the single biggest killer for me is AI traffic, much more than Terrain LOD. If I turn that off my main thread improves and I can keep at around 58 fps average, with AI traffic on and variety set to high, it drops down into the 40’s and my main thread is permanently red.
I’m going to to reboot now and then try again with my frame rate capped at 32. I basically want a smooth, stutter free experience, which now seems to mean flying without any traffic, which kind of sucks to be fair but fngers crossed for Direct X12 and some optimisations…
