CPU Affinities control which CPU cores a process is allowed to use. Its threads will only be scheduled to that set of CPUs. This is useful to limit max CPU consumption of a process, or to optimize which CPU cores are dedicated to specific apps, games or services.



Multi-group (64 logical CPU cores) processes have system restrictions on CPU affinities. Process Lasso will make a best effort to move threads to your chosen CPU affinity, but new threads of a process won’t be constrained to the desired CPU affinity without continuous reapplication of the affinity. Process Lasso will do this automatically if you create a persistent CPU affinity rule. However, you may instead want to use the CPU Sets feature, a softer form of CPU affinity, since it does not have these multi-group restrictions.
