No Am , no HT . Core ) is the mainj thread and the other 5 cores are for terrain loading.

Here one of my 2 batch files

I noticed you didn't start Prepar3D.exe from a batch, why is that?

Thanks

Is it same in your second batch file that you mentioned?

Thanks.

AM of 4084 seems best for me.   I assign low demand parallel running add-ons on LP 0 and 1, and P3D main on 2-3, and I see strong evidence in complex scenery each LP is cranking out way more than 50%--sometimes I'll see them all at 80-100% w/ 2-3 running at only 74%.  I have to think more cores is better so I may go w/ a 10 core next build.

That is a debated topic... just because you see work being done, does not guarantee smooth operation..  :blush:

Think of  "Too many cooks in the kitchen"  for a useful analogy..

Sure, but I have both ultra smooth operation and fast terrain texture update rates, so what's not to love ;o)  I don't think that analogy applies at all.  Every one of these cooks have their own space to work in and they're all good friends and work together very well anyway!

It seems there are some addons that don't allow such AM control...

Just tried to launch 'FSiPanel' with:   C:\Windows\System32\cmd.exe /c start "FSISERVER" /affinity A0 "F:\P3D Apps\FSiPanel 2017 for Prepar3D\FSiPanel2017_P3D.exe"

It still launches, but using all cores/LPs

Nor will this addon allow 'Process Explorer' to view which cores it uses, although 'Process Lasso' will report on it.

Interesting - not seen this before.

I would go through this post in particular:

 

Get a New cpu to test , its delidded shall  run  it without  HT to get  higher OC and less heat 

Hope to get 4.8ghz out of it.

I am not calculate affinity  often. 

Am 65535 2cores free  111111111111111100

Am 65532 4cores  free 111111111111110000

Is this correct.

Are you asking?

Sorry which cpu is this and how many cores do you have?

Thanks
