Does Cortex Auto set the CPU Affinity?

I recently stumbled across a program called process lasso. You can look up what it's supposed to be good at, but in summary, it can set the CPU affinity of all the system processes to some of the available cores, and the game you are playing to others. With the CPU affinities set like this, games can rely more on the CPU cache, and get better FPS because nothing else will be running on the same cores and dirty the cache making the CPU pull the data from somewhere else slower like the RAM or hard drive.

I tried Process Lasso for a bit but it made my computer restart randomly the next day I turned my computer on. Once I uninstalled it, the restarts stopped. I'm not sure, but I think the restarts were from some of the windows processes trying to restore default CPU affinity. Instead of being set to something like 0-3 they were showing as set to X0-3.

So if Cortex does not already do this, can it be made to optimize the CPU affinities while boosting, then restore them when done?

I have not done the testing myself, but according to the main source that I learned about this form, they were able to boost FPS in Fortnite by 100.
hello can u explain how you do that? i face the same problem here..interest how u fix that restart problem
I fixed it by resetting all the affinities and uninstalling process lasso.
From the testing I have done, Cortex does in fact optimize the CPU affinities. That makes it a much better choice.
