Process Affinity Utility

What is this?

A simple software to help you to set the affinity of a given process.
This means you can select what cores you want to allow a specific process to use.

Why?

Sometimes you may want to make sure a process doesn't use all your processing power, or perhaps due to bad implementation it doesn't work properly when too many cores are assigned to it (I'm looking at you Spellforce III).
This software is a utility to help you with this task, which can also be achieved by simply using the windows task manager. It supports profiles so you that you don't have to set everything manually every time.

I put a lot of effort and brain power into this content.
Please consider buying me a delightful cup of tea.
