I set 45Hz for experimental purpose, since it is easier for the sim to maintain 45 fps, reflecting in a lower CPU load than at 60 Hz/fps.

Why 45 not 30? What specifically do you like in number 45? Just curious. Your monitor is not 90Hz or 45Hz anyway..

PS: and rule britanni...the waves!! 😄

45Hz is the absolutely lowest refresh rate my current monitor can go for. It can't do 30 Hz.

P.S.: Yes, I watched the football game in Germany. 😄  Well played!

Ah, Ok got you.

Thanks.

I’ve been away for awhile and I see that this thread is 34 pages long! Is there by chance a solution to the excessive CPU usage in v5.2? I started to read through and I am thoroughly confused.

Cheers, Pete

What worked for me was setting an Affinity Mask that only used one logical processor per core rather than using all 12. Depends on your CPU and whether Hyperthreading is enabled in your BIOS.

I am not even sure what that means. I have a Ryzen with 8 cores. I don’t know what I am looking for or how to find it. Are you able to provide some assistance?

Hello Pete, first off an easy problem for you to solve: find out if your Ryzen comes with Hyper-Threading capability and what it is called in AMD terms. Please google this, look it up, you'll need to learn and  understand this pc science anyway if you really want to know. 

Cheers,

Thanks Dirk! I will check on that in a few minutes.

Pete, this was my breakthrough...

https://www.avsim.com/forums/topic/602488-cpu-core-0-used-more-than-gpu-in-v52/?do=findComment&comment=4555575

There’s plenty of discussion about cores and logical processors in the pages around the above post. Your CPU has 8 cores but if Hyperthreading is enabled in your BIOS that equates to 16 logical processors - 4 more than mine.

That should give you enough info to follow the logic hopefully.

Okay, so I have a Ryzen 7 3700X 8-Core which apparently has hyperthreading or SMT.

Now, what is your motherboard's brand and model? And your Graphics card for that matter?

Or perhaps PM me your contacts if you want to.

Sorry for my ignorance, but where would I find that?

Ok, PM me otherwise we'll flood this place in no time.

You do see less than 100% with the 45Hz setting and VSYNC=ON in P3D Display Settings with Unlimited on the slider. So I would just go back again and check I set VSYNC=OFF in P3D and Unlimited on the slider, start with low settings, make sure the Prepar3D.exe Profile in NCP has been restored (and the general tab) and only change the fps limiter, in the NCP P3D profile with nothing else changed.

However it is possible some monitors make different results with these techniques, that is why we have to test carefully.

I made an important discovery as to why I had 100% load when limiting frames via NCP: I set the "Power Management Mode" to "Maximum Performance" (as you can see in the video). When I reset all settings to factory defaults, it set that mode to "Optimal Power", and under that mode I had 70% or so core0 load - a reasonable value. After changing other parameters, I isolated the behavior down to this setting.

But I thought that "Maximum Performance" was the recommended setting for P3D and MSFS...  If you read guides on best NCP settings here on AVSIM and elsewhere, you will find that almost everyone recommends setting the power management mode to maximum performance, which intuitively makes sense ("Why should I limit the power of my GPU, right?"). But it pegs core0 to 100%...  You can give it a try to verify it.

Anyway, I am tired now - will do more experimenting tomorrow.
