This depends entirely on your setup and what apps you want to run on Bluestacks. It could also be useful to limit some of these resources in order to improve your CPU usage. You may need to allocate more CPU cores and memory to the emulator. Most of the time, you don’t want to mess around with resource allocations for a program, but it’s pretty much necessary with Bluestack. Your Resource Allocations Aren’t Managed Properly That aside, there are two possible reasons why Bluestacks is using a lot of processing power-maybe even more than it should. It’s fully using that 30%, however, so Task Manager translates this to 100%. Since it’s allocated as a dedicated resource, Task Manager sees this as 100% of the CPU resources you have, even if the program only took 30%. When you run Bluestack, it only takes as much RAM and CPU power as it needs at that moment. Normally, when you open up Task Manager and see CPU usage, it’s showing you data based on set bounds (0%-100%). The other part has to do with how your computer allocates CPU usage as a dedicated resource. It also allocates some of your RAM and CPU usage as dedicated resources to do this. An emulator like Bluestacks uses virtualization to simulate hardware functionality and create a virtual Android system.

Part of the reason why you’re seeing high CPU usage simply has to do with what Bluestacks is and how it works. Why Your CPU Can Go Up to 100% Utilization With Bluestacks Set the Process Priority for Bluestacks in Windows Task Manager.
