NotCPUCores: Limit CPU Cores

Free, open-source alternative to CPUCores, limiting CPU cores for improved performance in gaming and applications.

What is NotCPUCores?

NotCPUCores is a free, open-source alternative to the popular CPUCores software. It serves the same core purpose of allowing users to limit the number of CPU cores or threads that a specific application utilizes.

This can be useful for improving performance in some games or applications that do not properly take advantage of multiple CPU cores. By restricting the app to one or two cores, it forces better usage of those cores and can eliminate stuttering or stability issues.

NotCPUCores has a simple and lightweight interface that allows configuring per-application core affinity profiles. You can easily create rules for different executables that will automatically restrict them to a set number of CPU cores whenever they are launched.

Since it is open source software, NotCPUCores is completely free to use with no restrictions. It runs on Windows 7, 8, and 10 platforms. The code is actively maintained on GitHub by a small developer team and community.

Some of the key advantages over CPUCores include:

  • Completely free and open source
  • Lightweight and easy to use
  • Actively developed and supported
  • Allows per-app core affinity profiles
  • Auto-applies profiles on app launch

Overall, NotCPUCores provides a great no-cost alternative for limiting the number CPU cores used by apps to improve gaming performance.
