What affinity mask value to use to keep all 3rd party apps off core 0?

Recommended Posts

I am using Prepar3D v4, and I have add-ons such as PFPX, Little Nav Map, Flight1 GTN 750/650, ChasePlane, FS2Crew, GSX, FSUIPC, etc... How would I reserve core 0 strictly for Prepar3D exclusively while all the others are using my other cores? I want to maximize and prioritize my CPU to run Prepar3D as efficiently as possible.

I have i7-3770k overclocked to 4.5GHz, with HT on... could someone tell me what Affinity Mask value to use in my prepar3d.cfg file?

Simstarter NG or Process Lasso to set core assignments

So what about the affinity mask setting? Is this not required then?

Setting the AM with the above is a really bad way of setting it, you need to use a AM for P3d, anything else you can use lasso but not P3d.

Hi, can some please help as I have no experience on how to use Process Lasso?  How does this work and how do you install?

Affinity Mask does not affect any other process than the P3D process. Affinity Mask tells P3D, and only P3D, which logical processors to use. Any other process separate from P3D will have to use some other method to tell it what logical processors it can use. This can be done with Windows Task Manager, batch scripts, FSUIPC, Process Lasso, and Sim Launcher tools that can set processor affinity.

Okay so how can I set P3D to run on another core besides core 0? Since 0 will be used by all other apps? What affinity mask setting do I use?

It's pretty simple.

In P3D you set the affintymask so that for example P3D runs on cores 2-7.

You install ProcessLasso which is pretty straight forward. In Lasso you select with a right-click the process und set the affinity. There are two ways of setting it: Only for the current running process or always when you start the process. You say "always" and pin the addons to cores 0 and 1.

 

 

In my eyes pretty simple :-)

And here you calculate your Affinity Mask: http://www.gatwick-fsg.org.uk/affinitymask.aspx?SubMenuItem=hardware

 

in my example (4 cores with HT and offloading Cores 0 and 1 for addons) you would set in P3D:
