Windows 10: How to set the affinity of an app to single core ?

Hi everyone,

Recently I had this weird issue where my output sound is disgusting when the affinity of "audiodg.exe" is set to more than one core.



I'd like to know if there is a solution to set the affinity of an app to single core without specifying which core ?



Thanks

Unable to set core affinity

I haven't played with setting core affinity in a long time. I also don't use the Steam ecosystem.

If there are multiple processes under a single heading, "Go To Details" isn't available for the whole set. It is available for individual processes. I hope that it's easy for you to determine which of those is appropriate. An example from an uninteresting application:

 

How to set 8 core cpu in affinity settings

Here is how to set your affinity settings using 8 core cpu splitting them into two 4 cpu cores

cmd.exe /c start "WoWSLauncher" /affinity F "C:\Games\World_of_Warships\WoWSLauncher.exe"

As you can see I added "F" next to /affinity that will let you use just 4 cores 0,1,2,3

I can do it easy in task manager but got to keep doing it everytime i want to play the game.

So if you want to use 0 1 2 3 cores just for the game you would add "F" in your line like so..

for cores 4,5,6,7 Do this....

Add F0 next to /affinity like so

cmd.exe /c start "obs32" /affinity F0 "C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe"

cmd.exe /c start "obs64" /affinity F0 "C:\Program Files (x86)\obs-studio\bin\64bit\obs64.exe"

Depends on if using 32 or 64bit of the os.

If doing it for obs it will not work as it can't find locale\eng-US.ini and failed to load locale but file is there.

So thats how you would set your affinity settings splitting 8 cores into two 4 cores

Am using windows 10.

You want to use 0,1,2,3 for the game and 4,5,6,7 for obs.

Only thing is that it does not save the settings of affinity after you exit the game it will return back to 8 cores when you start the game again.

So if anyone knows how to Save the settings then please post here as i have hunted on the net for awhile now.

 

Parked cores? Windows 10

Hi,

Thank you for posting in Microsoft Community. I understand your concern and I will certainly help you with it.

Many apps don't use all cores. They aren't programmed for it. Then they will use one core and will overload it.

But you can tell Windows to run that process on 2,3, ... and in all cores.

For doing it, follow these steps:

• Open Task Manager
• Select tab Processes
• Right click and select 'Set Affinity'
• Select on which cores you want to run process.

Hope this post helps. Get back to us for further queries. We are happy to help!
