BlueStacks is a cross-platform emulator that allows Android apps to run on PCs running Microsoft Windows or macOS. Because of what it does, users often experience BlueStacks s high CPU usage on their PCs.

Therefore, it’s essential to sort out how to speed up BlueStacks for faster Android gaming and other apps on PC.

Why does BlueStacks cause high CPU usage?

Bluestacks uses a lot of CPU power and memory (RAM) to run its processes. It is because running an Android app on Windows requires more system resources, resulting in BlueStacks s high memory usage.

However, many factors may add to the CPU usage problem on BlueStacks. Some are:

  • Outdated BlueStacks software – Bugs can cause issues with the BlueStacks software if it’s outdated. The bugs can affect its performance and cause it to utilize more resources than expected.
  • System Requirements issues – BlueStacks consumes lots of CPU resources because its activities require more resources to run Android apps. So, if your system doesn’t meet the requirements, it won’t run BlueStacks smoothly.
  • Other apps – Background apps running on your computer can cause low system resources in BlueStacks.

Other factors, including wrong display settings and a disabled Virtualization feature on your PC, can cause the problem. Nevertheless, you can limit BlueStacks CPU usage by tweaking your PC.

How do I stop BlueStacks from using so much CPU?

Before trying any advanced troubleshooting, go through the following:

  • Close unnecessary apps on your computer.
  • Temporarily disable antivirus software on your PC.
  • Restart Windows in Safe Mode and check if BlueStacks’ high CPU usage persists.
  • Because BlueStacks is a CPU-intensive program, it requires a system that can run without stress. So, check the minimum and recommended system requirements for BlueStacks to determine whether your PC meets them.
  • However, if your PC isn’t compatible after checking the system requirements, switch to a PC that meets them. Also, you can upgrade the required resources.

If you can’t fix it, use the following solutions to stop CPU usage.

1. Set RAM priority for BlueStacks

  1. Press the Ctrl + Shift + Esc to open Task Manager.
  2. Right-click on BlueStacks, then select Go To Details to open the Details tab.
  3. Right-click the highlighted process, and select Set priority from the drop-down. Set the priority level to Realtime or High.
  4. Close the Task Manager and check if the problem persists.
