Good day, I built a gaming pc last month, with 11700kf and a RTX 3090, mainly for flight simulations (DCS World, MSFS). In MSFS, it’s difficult to handle 4k@60fps, probably due to single thread issue of the game.

Acqually I have gpu load about 40-50%, cpu similar but with single core heavy workload in windows task monitor, and the warning of Main Thread Limit in dev mode. I’m using TLOD/LOD around 80-100.
Actually I see fps drop when rotating virtual view in cockpit (it drops to 40-50fps, then returns to 60 once view is fixed)
Do you think upgrading from 11700kf to 13700kf (13900) will change this substantially, or not?

I chose the 11700 because I thought the extra cores would be useless with msfs, but seeing now that performance is at its limit , I think maybe the more modern 13-series architecture could warrant me an improvement and let me stabilize 4k@60fps.

What do you think? Is it worth the cpu upgrade?

Get a 4080/4090, turn on frame generation, and go fly! Simple as that. 

No, do as suggested above.

To add to the comments above, as counter intuitive as it may seem, upgrading your GPU to 4000 series and turning on frame generation will at least double your current FPS. A CPU upgrade may get you 30-40% improvement but that's a far cry from the aforementioned 100%+ boost.

I went from a 12700 K / 32 GB ram / 1080 Ti to a RTX 4080 and basically got 4x fps in most situations using frame generation.  Be advised though if you do not have at least a Gysnc compatible monitor you will get vsync tearing issues in frame gen.

I don’t notice tearing here. Can’t use Gsync because of the awful flickering, that is perhaps even more evident on my OLED screen.

Then you need a proper g-sync monitor. Flickering is caused on g-sync compatible screens. It doesn’t happen on g-sync module screens or g-sync ultimate.

The LG OLED TVs do have Gsync support. The issue is actually better with FG activated, considering that it is mostly caused by low fps when using 120Hz+ screens.

Yes but they’re only G-Sync compatible, not proper g-sync. I have both and a real g-sync display is way better than the LG TV’s with g-sync compatible. 
And yes I agree with you RE the higher frames.

I use a 4K 60Hz TV, with no G-sync capabilities whatsoever, as my main monitor and I don't get any tearing with frame generation enabled.
