This is funny because Ive been attempting to research cpu affinity and game performance when In UMA mode. I’m so happy that L1techs has done a video on it to shed some light here.
What I have noticed is that some games that use anti cheat software, such as Easy Anti-Cheat will prevent you from setting the affinity through the task manager.
I think this is a worthwhile to dig deeper on this topic. Could someone post a link to the powershell examples? I would like to know of permanent ways to set the cpu affinity/thread pin certain applications, hopefully without using 3rd party software.
