Despite continuous improvements in BlueStacks’ performance and user experience, some user still complain that “BlueStacks feels slow” or “Bluestacks lagging in windows 10“. However, the users on older versions of BlueStacks face more performance related problems. In worst cases, BlueStacks can hang your PC as well.
First of all, we suggest the users to upgrade to latest version. With the release of BlueStacks 4, most of the performance related issues have been solved. However, if you’re still experiencing lag during gameplay or BlueStacks is hanging your PC, you are at the right place. Increasing RAM and CPU, enabling Virtualization and tweaking Antivirus will speed up BlueStacks and you can use it without hanging your PC.
NOTE: If you are using older version of BlueStacks, you can try this tutorial to increase RAM and improve it’s performance.
This tutorial shows, how to speed up BlueStacks and run BlueStacks without hanging your PC. This tutorial works for BlueStacks 3 and BlueStacks 4. But if you are using older versions of BlueStacks, you can check this tutorial for increasing RAM. Let’s continue with the process.
1) Increase RAM and CPU to make BlueStacks Faster
If your computer has plenty of resources, you can allocate more RAM and CPU cores to BlueStacks to make it run smoother and faster. In older versions of BlueStacks, you had to make changes to Registry in order to increase RAM, but in BlueStacks 3 and BlueStacks 4, you can directly increase RAM and CPU core from BlueStacks’ Settings. Follow these steps:
- Run BlueStacks, click on gear icon on top-right corner of BlueStacks window and select Settings.
- In Settings, click on Engine on left side. It will show you current values of allocated RAM and CPU cores. Move slider to adjust RAM size allocated to BlueStacks.
- You can also increase CPU cores by selecting number of cores to allocate to BlueStacks from drop-down list next to CPU cores.
- The changes we made, require BlueStacks to be restarted. After increasing RAM and CPU cores, click on Restart Now to restart BlueStacks.
BlueStacks will be restarted. Now BlueStacks will run faster with more RAM and CPU cores.
WARNING: You are advised not to assign more than 50% of your System’s resources to BlueStacks. This way you can run BlueStacks without hanging your PC.
2) Enable Virtualization in your Computer
Enabling Virtualization technology will make BlueStacks 3 & 4 to run smoother and much faster. Most of the CPUs these days support Virtualization technology. However, Virtualization is disabled by default and you have to manually enable it. You can enable Virtualization on your computer by going to BIOS settings. The method for going to BIOS settings differs on every PC manufacturer.
How can I find out if my PC supports virtualization?
You can download and run a free utility provided by your PC’s CPU manufacturer. The CPUs are majorly of two type: Intel or AMD. Both of them provide free utility to help users check if the CPUs support Virtualization technology. You can download Virtualization Detection Utility from the links below:
How can I enable virtualization, if available but disabled on my PC?
The process of enabling Virtualization technology is different for different processor types. You can check this detailed tutorial on how to enable virtualization in your PC.
3) Check if your Antivirus is causing BlueStacks to run slower
Sometimes Antivirus programs that use Virtualization technology, acquire resources that are necessary for BlueStacks to run smoothly. This may make your BlueStacks laggy. Specially if you are using Avast Antivirus, BlueStacks may lag even more on your system. Follow these steps to change Settings in Avast antivirus and make your BlueStacks 3 & BlueStacks 4 faster.
- Go to ‘Settings’ of Avast-Antivirus as shown below.
- Click on ‘Troubleshooting’ on the left-hand side, uncheck the ‘Enable hardware-assisted virtualization’ option then click on ‘OK’ to confirm and reboot your PC.
You should experience BlueStacks running a lot faster and smoother after changing this setting.
4) Few more things you can try to speed up BlueStacks
By now, your BlueStacks would have become really fast. However sometimes despite having done all good settings, a few things make BlueStacks run slow. You can try few more settings to make BlueStacks 3 or BlueStacks 4 faster:
Keep your graphic drivers updated
It’s a good idea to keep your Graphics driver updated. Sometimes old and obsolete graphics drivers cause BlueStacks to run slow or laggy. You can update your graphics driver from Windows Update or download latest version of Graphics driver from your PC’s manufacturer’s website. If you are using dedicated Graphics card, don’t forget to install latest driver for your dedicated graphics card. This will make your BlueStacks run faster and smoother and improve your Windows performance as well.
Close Applications that are using more Resources
Sometimes running multiple applications simultaneously makes BlueStacks run slow. If some resource heavy application is already running with BlueStacks, it might cause lagging in BlueStacks. Plus, it may also hang your PC. So, it’s a good idea to close resource eating applications while you are using BlueStacks.
You can close applications running in background using Task Manager. Open Task Manager, in Processes tab right-click on the application that is using more resources and select End Task. Make sure you save all your work before killing any application to avoid data loss.
Speed up BlueStacks by increasing the RAM and CPU Cores
By following above steps, you can make your BlueStacks run really fast without hanging your PC. Hopefully lagging issue in your BlueStacks is now solved. If you are still using old version of BlueStacks, you can try this tutorial to increase RAM. Or even better, you can upgrade to latest version for great gaming experience on big screen. Enjoy and have fun!
