SU14 DX12 hyperthreading on. 

Nope, no luck. I went back to process lasso, DX12, FG, but same behavior:

I have an i7-12700K with HT On and I see similar results as Cpt Piett, 

I am climbing through FL 280 in the Fenix at 97 FPS and I am seeing the following:

Pcore 1 - 58%

Pcore 2 - 60%

Pcore 3 - 54%

Pcore 4 - 53%

Pcore 5 - 58%

Pcore 6 - 63%

Pcore 7 - 63%

Pcore 8 - 57%

Ecore 1 - 24%

Ecore 2 - 20%

Ecore 3 - 20%

Ecore 4 - 21%

Temps sit around 55 - 60 degrees

Running Ultra settings with TLOD at 300 (Managed by the awesome adaptive LOD program), FSLTL 

I also run Windows 11 Pro

The only issue I can see from your screenshot is those 2 cores 100% maxed out. Are you worried about being mainthread limited? I've got almost exactly the same mainthread value as you. Also, you're getting decent FPS. 

@ttbq1 Perhaps you should try with hyperthreading on? Your CPU has 8 P-cores (16 threads with HT on), 16 E-cores - a total of 32 threads. Having 16 P-core threads should even out the usage across the threads, minimizing the risk of a few threads maxing out. 

Although, @RJC68 gets an even usage across the cores like me, despite having as many P-cores as you have (without HT). 

@ttbq1 I would also suggest that you don't have Lasso set to some manual core affinity with MSFS. I've tried that and it lead to huge problems. I've only got the following settings for MSFS: CPU priority high and Bitsum highest performance. I would also suggest enabling ProBalance.

I am beginning to wonder if this is a BIOS setting causing the difference.  On my eight power cores, numbers 4 and 5 run between 85-100 percent, while the rest are just out for a jog at about 30%. 

The E-cores don't even come into it.  just 10-15 percent on some maybe for just windows background processes.  Strange. 

Lmk if you figure out something Rob- I’m jealous of those even core loadings…

I went back to default BIOS settings with HT on and all ecores enabled and got exactly the same behavior on core 4 and 5 at 100%. No stutters whatsoever.

Process Lasso is only used to assign other apps (lnm, lod, charts, fsltl, etc) to the ecores. 

I don't have a bad performance, I would like to have your settings on capframex to check if I have same level of smoothness 

Thanks

Too bad enabling HT didn't work, I guess it was worth a try.

I'm not sure if I understand 100%. Do you mean settings in capframex, or more general settings (sim settings, nvidia control panel etc)?

I did the following test:

Fenix A320, Inibuilds EGLL, AIG AI around 100ac, takeoff and landing 27R, TLOD and OLOD 180, TAA, FG, DX12, 4k, Gsync monitor 120hz capped with Vsync on NCP.

And the same test without AIG AI (same scenario as above)

Have you gone deeper into this? I have Gigabyte Z790 Aero, maybe a BIOS setting affecting us?

That’s a great result. It’s possible that those two cores maxing out doesn’t matter much.

Two cores “maxing out” is, surely, expected in some of the conditions which are now normal with an intel cpu, where their confusingly-labelled various “Turbo” etc modes can sometimes boost the clock speed of up to 2 cores.

One would expect - and certainly hope - that Windows and MSFS co-operate well enough to schedule the most demanding tasks to whichever two cores are, for the time being, boosted in this way.

That might also explain why some people see different patterns: different CPUs, or different settings in the UEFI as to whether the CPU should operate in a mode capable of boosting up to two cores (even if this mode is available, it can be turned off - maybe inadvertently, bearing in mind the hopelessly opaque text / labels on any overclocking page in any UEFI).
