Start .exe with a set Affinity

[Nineballo]

How would one create a (.bat) shortcut to a steam game (R6) to run it only on cores 1-4, leaving 0 and 5 for the system and other tasks?

 

To my knowledge this cant be done with the /Affinity command (unless i did it wrong) due to the fact that steam spawn's the process and the process takes steams affinity and priority settings.

From Dos, with "copy con" command.

google it.

"Copy con is an MS-DOS and Windows command line command that allows the creation of a file through the command line. To use this command, type copy con followed by the name of the file you want to create, as shown below."

 

To my knowledge this just creates/duplicates's a file, how would you change affinity's with it?

This will have to be edited for your use case, but figured if anyone stumbles on this in the future they should get the answer...

 

 

@echo off

cd C:\Users\NineB\Documents                   

"Tom Clancy's Rainbow Six Siege.url"

echo R6 Started

ping 127.0.0.1 -n 101 > nul                                                   

Echo Changing Priority to 1-4

PowerShell "$Process = Get-Process RainbowSix; $Process.ProcessorAffinity=30

Echo Done

Pause

"Tom Clancy's Rainbow Six Siege.url" #Starts Shortcut placed in said directory

 

echo R6 Started

 

ping 127.0.0.1 -n 101 > nul         #Wait 100 sec for program to start up (kind of a misused... but it works)   

                                  

Echo Changing Priority to 1-4 

 

PowerShell "$Process = Get-Process RainbowSix; $Process.ProcessorAffinity=30 #Changes the process affinity to use cores 1-4 leaving 0 and 5 for the system

 

Echo Done

 

Pause #you can change this to exit if you want cmd to close
