Yeah, I can see that your CPU usage differs (edit - actually, in 2 of the 3 situations you’ve posted you also seem to be CPU bottlenecked).
I can also see how the playing situation differs. From the screenshots you posted, you seem to be GPU bound - GPU utilisation up between 96% and 106% (???). If you were to try that same flight again with the developer tools on, I guess you’d see “Limited by GPU” not “Limited by Main Thread”. This is also the case for me when I’m up in the air like that. My FPS is around 70 and it says “Limited by GPU” - perfectly undestandable.
What we’re all talking about is when this changes to “Limited by Main Thread”. This screenshot was taken simply on the ground in Barcelona El Prat in a Cirrus SR22 sat at the end of the runway. Since this airport is very close to the center and has photogrammetry for La Segrada Familia, it’s using lots of CPU resource for doing that. This means that I’m being limited by my CPU load. As you can see, this is causing my CPU to be used 100% on one core, meaning I’m limited by single core performance.
You’ve previously said I’m catagorically wrong on that but the proof is in that image and your own response to it.
Now, since this doesn’t seem to be getting us anywhere, I don’t think there’s much more to discuss. I posted by conclusions (in post 331) and I stand by them. Without the developers improving the game engine and/or implementing DX12 support, then most of us will continue to be CPU limited most of the time unless we go about overclocking the CPU. I also stand by that adding more CPU cores will not make it better if they are running at the same number of calculations per cycle and the clock speeds are the same. This is because it’s the single core performance of the CPU which is holding us back, not overall CPU usage.
Finally, I heavily doubt that posting a link (which presumably is protected by a login etc) violates your NDA.
