9700K, 8 cores, no HT!? 

Thanks! 

This CPU DO NOT support HT . I own the same CPU.....

I know Maurizio, thanks - but not everybody knows it and I'm still looking for the best settings. Unfortunately, I still don't really understand the calculator...

There is not really much need for an affinity mask without HT, I wouldn't know what to set it at to be honest. What is more important in this case is keeping all other programs off of core 0 (the first core), which is the main core used by P3D by default. This however is bit more complicated.

I thought Rob’s post yesterday made it clear. Look at my earlier post with a screenshot of my Task Manager.

That doesn’t prevent you using a suitable AM. I’ve disabled HT on my i7-8086K. It allows you to overclock that bit more as HT causes more heat.

@MAUCINTI,

For an 8 core non-HT processor try this:-

   [JobScheduler]
      AffinityMask=255
      P3DCoreAffinityMask=126
      MainThreadScheduler=0
      RenderThreadScheduler=2
      FrameWorkerThreadScheduler=4

That means P3D will be assigned all 8 cores but only use cores 1-6 for processing. core 0 is assigned the the OS and core 7 is for any programs like weather, moving maps etc.

You should assign those programs to an AM manually by opening Task Manager, Details tab, right-click entry and choose Assign Affinity Mask. Alternatively, use Project Lasso for the assignments.

I'm really curious as to what is happening on Core 0. The OS should idle at a very negligible amount.

On a side note, I'm surprised that LM hasn't implemented something like what they have in the MSFS2020 SDK - something indicating when the target frame rate cannot be achieved and what is blocking. I'm also disappointed that they haven't implemented warnings when the sim blocks for more than a certain period of time. That would go a long way to at least identifying what the cause of micro-stutters are, and then ideally resolving them.

Cheers!

 

 

I have now taken these settings for AMD 5800x .. 8 cores HT on are these settings ok? with ASPD

 

[JobScheduler]

Affinitätsmaske= 65493

P3DCoreAffinityMask= 65493

MainThreadScheduler=0

RenderThreadScheduler=1

FrameWorkerThreadScheduler=2

Thanks a lot, Ray and Maucinti!

Possibly a lot of unnecessary services and executables like DropBox and CCleaner. Rob A has probably stopped most of those.

Does anyone know if SimStarterNG can temporarily stop services and then resume them once P3D has terminated.

Luke, see my prior post here ... yes the OS is doing very little other than standard housekeeping or automatic updates or other stuff it loves to do without asking

Task Manager should be able to display the executing process and its CPU usage without difficulty. I'm not as ready to give up and blame the OS when Ray has over 180 processes executing. I see the odd blip on my own PC but that's pretty constant and there's probably some helpful data if he can track it down.

To be somewhat pedantic, a DLL cannot control its processor affinity - that can only be done at a Thread/Process level, since the same DLL can technically be loaded by multiple discrete processes and threads each running with their own affinity.

Interesting, where are you finding this, I don't see it in the FPS metrics?  All I see are "Limited by MainThread" and "Limited by GPU" ... I don't see anything really useful as in this object ID/GUID triggered the event ... I can sorta point in a direction to see but that isn't very useful.  Can you expand on how you find value in this or are you discussion some other feature I missed out on?

No, that's it - I agree that it's not hugely useful on its own, but it's a start. There is no substitute for logging what's blocking and then exceeding its time budget when debugging stalls in a latency-sensitive application. Everything else is just rooting around in the dark and I'm surprised that neither LM nor MS have fully gone down this road, to help their own developers as well as others.

Cheers!

Before you randomly shut stuff down, I would definitely look in Task Manager and track down the offending processes. You have the data, why not use it? 😉

Cheers!

I have no intention of shutting down services at random. Some are obvious and those will be the first to go. Yourphone.exe is one example of a useless process.

But having searched the SimStarterNG forum there is no option to terminate services and then restart them. The thought process being that because there's so much RAM stopping them achieves very little in 10 compared to earlier OSs.

OS is using around 10% - not that different to Rob's if you look carefully at his screenshot.

I need some help to understand all parts of JobScheduler in P3D. I have an I9-9900K, using HT and have followed Rob A's advice earlier in the thread. I have moved P3D off core 0 and put P3D on cores 1-5 (not any HT core). I use core 6 and 7 for AS, Chaseplane and a few others. Now to my question. This is how it looks in P3D.cfg after changing as above.

AffinityMask=65535
P3DCoreAffinityMask=1364
MainThreadScheduler=0
RenderThreadScheduler=2
FrameWorkerThreadScheduler=4

I assume that MainThreadScheduler=0 should be changed to =1 because I have removed P3D from Core 0. And what values should be specified for the entries RenderThreadScheduler and FrameWorkerThreadScheduler. Or is it that all the values in these three entries should be left untouched?

As you can see, I need some help to understand

Unless you've masked off all 180-odd non-flightsim processes to only use Core 0, I suspect there's something in there that isn't the OS. Either way, just something curious I noticed. You can do with it what you wish.

Cheers!
