I’m tired, tired of all the things I’ve tried to eliminate the extreme CPU usage when at cruise altitude. Doing a flight from EHAM to EDDB (with PMDG or Fenix) which only takes 1 hour 15. As soon as I reach my cruising altitude my temps increase to 89 degrees, and FPS drops immediately. After a few seconds temps are back around 60, and back to 89 etc etc
Is it because of clouds? Cache? Contrails? Screen rendering?
Normally this should be around 60-65. I can clearly see spikes in CPU usage.
Switching between DX11 & DX12, clearing caches, rolling cache on/off, fully reinstalled windows, SMT on/off, with and without possible tweaks I could find, lowering settings… And so on.
What more can I do? My joy of flying is gone.

1/ Have a good cleanup of your PC case, remove any dust etc. and clean the fans. Make sure there is adequate ventilation. I know this will sound obvious but it won’t help your temps if the vents are clogged up and of course when they get too high Windows will reduce the power so your FPS goes down the drain.
2/ Have Task Manager running and visible. Look for other programmes and processes that may be using your resources.
3/ You don’t mention Community Folder. Have you tried removing all addons in case one of them is the culprit? This is usually the first thing to check and I sort of assume you’ve done it.
Quick edit as thought of something else. Is your Power Supply big enough for any changes to hardware you might have made, or maybe it’s failing.Could be the source of overheating.
Have you updated the Fenix to the latest version that released a couple days ago? If so, check your task manager and see what the Fenix App is using.
There is a known bug where the app is using allot of CPU and spawning many processes. They did release a patch but it hasn’t resolved the issue for all who have it (and the issue doesn’t occur for everyone).
That’s exactly what I was thinking about.
Rendering that much detail would seriously tax on the hardware so it’s pretty obvious that you can fry bacon and eggs in the gally, using the heat of the CPU/GPU.

That’s the same behavior I observed since my beginning with MSFS. It’s dependend on the region I overfly, for example World Update Germany seems to be very heavy, followed by UK. France or Spain gives lighter CPU load and over the water the CPU is resting.
The load is always jumping up and down between nearly 100% (highest CPU core reaching around 80°C) and lower usage like 50%. The change in fan speed of my cooling is also audible. However fps fall newer below my locked 30fps (using vsync half refresh rate).
I have this on the Fenix (old and new version) and also on the PMDG. I asume it’s mainly terrain rendering/loading but I’m always wonderung why some specific areas are so bad compared to some others.
By the way, I’m using an older i5-9600kf with a RTX2080ti and 16GB RAM.
I have exactly the same experience. Germany seems to be very heavy on the FPS to cruise above. The good thing the FPS do recover again. Yesterday on a flight with the new Fenix I went from 37 FPS locked (vsync) at EHAM, to at some times 15 (!) FPS over Germany for brief intervals, and back to 37 FPS at destination in Slovenië.
I have really bad performance around 50km radius around Cologne. No problems anywhere else, even low down in New York. I really think there is a problem there. I have not tried with empty community folder yet but that whole area is just unflyable for me. No idea what the issue is, but I suppose there are quite a few cities with photogrammetry close by. Seems like an optimisation error somewhere there.
His temps are high because CPU usage is slamming through the roof. I’ve had similar lately it’s almost like the sim is trying to stress test the CPU during cruise no matter what setting you use.
I noticed the same on a recent high-level IFR trip in FBW320 judging by how the fans had ramped up.
But the subsequent low level trips VFR in the Bonanza were quiet and trouble free.
I had the same experience in the JF Hawk at high altitude. I never normally fly that high and it’s the first time the temps of the CPU have reached such high temperature. Ending the flight made no difference, I had to shut the SIM down.
I repeated the flight at low altitude and there wasn’t a problem.
EDIT: It’s not just at high altitude now. Just did a flight at mid and low level and soon after take off, the temps rocketed. Coming out of the flight to the main menu makes no difference - high CPU activity across all cores which immediately returned to normal after exiting. I’ve only come across this sort of CPU and temp issue in the last week or so.
I just opened a bug report regarding WU6 because I assume there might be something odd or very bad optimized. It would be great if users with the same issue could also report it there.
Stockholm to Helsinki on a 747 gives the same terrible fps result at 10.000 ft with fair weather. The trip is made most of the time over plain water. There´s no reason at all for such atrocious performance drops at some areas other than AAU2 poor performance itself. I have similar specs as OP.
