HI  Toby23

 

Thanks for the post and reminding us to put AM=14  into cgf.    I was not aware of LM's recommendation for this tweak. But now I got smoother simulation. 

 

And also I tried with 15, and that one works even better for me. Less microstutters, but higher temperature.

That's because you are no longer "robbing" P3d of a physical core.

Do you know if AM actually "forces" application to use selected cores, or just restricts it to selected cores?  If restricts, then it would be the same as not to set any AM.    

 

On Microsoft website they said this: "A process affinity mask is a bit vector in which each bit represents a logical processor on which the threads of the process are allowed to run. "

 

So it looks like it restricts, not forces. Then why it is better if AM is set to all, comparing to default not set anything, and OS itself will choose any of them?

 

I did the same on FSX with AM=15, and also got better result then without mask.

AM disables the application from using a core. which is why AM = 14 prevents P3D from using 3 of its 4 cores

Am=14 prevents P3D from using 1 of CPU's 4 cores. It disables core 0 and keeps core 1, 2 and 3 enabled. AM=15 enables all cores (which is the best setting for most users since it prevents blurries).

You are correct.

First of all thanks for the post.

 

Based on what you have to select the cores, LM stated to use all cores possible or some in particular?

 

If I well remember is best to switch off core 0, is it correct?

P3D v2.3 is now very well able to control this by itself. One need not to mess around with any AM in any way. That's pretty nice and works very well. Why not give it a try?

Just to close this topic, for now at least, the latest version 2.3 manages fine without ANY edits to the config, on my system. YMMV.
