Free download Bitsum CoreDirector Latest version - Real-Time CPU Optimization and Automation Tool.


Free Download Bitsum CoreDirector for Windows PC. This application enhances your system's performance by preventing specified processes from being scheduled to efficient cores (E-cores), ensuring they remain performant (P-cores). This particularly benefits demanding gaming, audio production, video editing, and streaming applications.

Overview of Bitsum CoreDirector

It addresses a common challenge faced by users with heterogeneous CPUs, like Intel 12th+ generation processors. The issue lies in the occasional undesirable scheduling of threads onto the efficient (E) cores, negatively impacting their performance. Since many applications have not been updated to provide explicit instructions to the scheduler, it optimizes thread allocation and improves overall system performance.

Why is it Necessary?

The necessity of this software arises from the inherent difficulty in managing thread scheduling on heterogeneous CPUs. The absence of specific application instructions leaves Windows relying on educated guesses for optimal thread allocation. Until applications are updated to specify their thread load types, it acts as a solution, preventing processes from being scheduled to E-cores and ensuring they run on high-performance P-cores.

How does it Work?

This software employs various enforcement methods to optimize core scheduling based on user preferences. Users can choose from the following options in the 'Options' menu:

  • Efficiency Mode OFF: Prevents threads from being put into Efficiency Mode. Avoids automatic scheduling to E-cores. Allows a process to use E-cores if its thread count warrants it or if it chooses explicitly to.
  • CPU Affinities: Restricts all threads to the P-cores.Exceptions for processes intentionally scheduling onto the E-cores. Process Lasso with 'Forced Mode' can be used to overcome a process's own choices.
  • CPU Sets: Intermediate method leaving core allocation decisions to the OS. Offers a balance between Efficiency Mode OFF and CPU Affinities.

System Requirements

  • Operating System: Windows 11/10/8.1/8/7
  • Processor: Minimum 1 GHz Processor (2.4 GHz recommended)
  • RAM: 2GB (4GB or more recommended)
  • Free Hard Disk Space: 200MB or more is recommended


Bitsum CoreDirector is a valuable tool for users seeking enhanced performance in resource-intensive applications. By intelligently managing core scheduling, it addresses the challenges associated with heterogeneous CPUs, ensuring optimal performance for a smoother computing experience.
