Hey guys I have an i9 9900k turbo enabled ht off not overclocked yet.

32 ram 3600mhz 

1080ti msi lightning z 

gigabyte aorus master

running all cores for everything  asp4  Asca P3d etc etc 

60hz 4k 55 inch

30.5 FPS locked in Nvidia inspector 

and prefer max performance in ncp

which seems to run quite smooth except from slight stutter here and there.

any benefits from going into affinity mask and moving addons off a particular core?

 

which ones would that be?

0, 1 ??? being the first Core

and have them run only 2 to 8? 
 

I get lost with this algorithm in other topics.

its got to be in simplistic form for a dummy like me lol

 

cheers

I guess not eh 

It's usually not needed. Windows Kernel is very good at load balancing, so if a process and it's threads reside on a flooded pipeline, then job scheduler will move it to other one which can complete the task faster. You could try affinity mask where you have one thread per core, could improve, could do nothing. Only way to find out is to try.

For some reason, some people are in a position where they can't utilize more than few cores efficiently, but I can load 12 cores, all to even 80% workload. I guess that at first place you should find out how your processor is utilized by sim. Download and open HWInfo during your simming session and see what the core utilization looks like.

Thank you for your response.

ill have to test

so if I were to just go into task manger if I were to get addons off core 0 and 1 ide just Untick 

 

The real-time P3D threads that might most benefit from unfettered use of a core generally run on core 0 (main thread), and core 1 (scheduling thread).  The rest of the CPU cores are tasked more intermittently when terrain and texture fusion and loading happens.  So restricting your other programs to cores 2-8 is reasonable, or perhaps even 7-8, leaving more headroom on cores 2-6 for P3D. 

For experimentation you can set the affinity in the task manager as you describe...if you see some improvement and want to make those changes persistent, you can use a utility that will watch for and modify the CPU affinity when it sees the process running (e.g. Process Lasso), or use a utility that writes a CPU affinity mask to the PE header of the program executable.  Or, if the program can be started using FSUIPC's "Runx=" command line, you can specify an affinity mask in the command line.

Thanks 

bit that’s where  I get lost, is with creating batch files.

unless someone posts a step by step video.

im clueless lol

I have had very good results using Process Lasso to assign cores on my previous i5-2500k and now even better on my i9-9900ks. It’s easy to use and experiment with and you can watch the core loading real time on its graphical display. Once you find something you like you just have the app auto launch and minimize and it works well in the background every time you turn your flight sim PC on. I’ll tried many methods to accomplish these results and tested countless combinations over the years and have settled on Process Lasso and personally believe it makes for a smoother sim with my setup. Currently I’m experimenting with only running P3D on 6 logical cores and no hyper threading based on conversations with “Steve” and believe it may even be better than running it across all 8. This leaves me with 2 other untouched  cores to run addons. One thing I have discovered is that since I use Chase Plane everything runs better if I enable Chase Plane to run on all the same cores I set P3D to run on, it has very little impact but seems to run much better on the same cores. This probably has to do with the primary rendering cores being matched or something related to that but I have definitely learned on my sim to keep them tied to the same cores.

Anyway my 2 cents and as we all know mileage will very sim to sim.

Wlll try lasso 

can you please share your settings 

eg which addons for which cores??

Would asp4  be on 7 and 8 etc etc 

thanks 

mike

The best is where at execution of an addon already has been determined which cores it is allowed to use.Not after execution as with PL.

In my case I use batchfiles.

Have a look at this

Gerard,

I understand this may be a cleaner approach because you aren’t running a separate app to accomplish a core pinning task but I haven’t found anything in my research that says it is best to do it before launch in terms of the desired outcome of performance we are all seeking. Could you please explain why having the app change after execution is not as good or different I’m very interested? I will take a look at the batch file method but for experimenting with the many addons and programs I use, Process Lasso has proved very useful and until now, potentially, I was unaware of any difference in the desired outcome of changing affinities before or after app launching.

Thanks in advance

Joe

Hi Joe-

What Gerard is trying to say is that it's not necessary to use (add) a system to manage a system.

I use FSUIPC to start and assign AM's on my system as P3D starts. No PL (overhead) or anything else required.

Cheers,

Mark

Hi Joe,

At startup they use the predefined cores which makes it more stable.

In the past I used PL and I have also tried using the task manager.

Then I tried Steve’s way as he explained why assigning apps at startup was a better approach. Now I am using batchfiles only for addons.

Later I will post an example of one of my batchfiles.

The correct AM icw using batchfiles has made system ( realsize cockpit with 3 pc’s ) rock solid. I never had to reinstall Windows or P3Dv4 till today..

regards,

Gerard

That is very interesting and I may have to try that.   Not that I need to, my sim is running great, but I am greedy.  If I can get a little more out of it, I'll take that route.

Here one of my batchfiles :
