How to Fix Lag in BlueStacks (Best Ways)

Experienced lag while using BlueStacks? Fret not, for this comprehensive guide will equip you with the knowledge to tackle lag issues and restore a smooth gaming experience.

Whether you have a high-end PC (Laptops) with 18-32 GB of RAM or you have a budget or low-end PC with 4GB or 8GB RAM, it is applicable for all of them. Even if it’s BGMI or if you are getting low FPS. We have all these solutions to try.

How I Fixed Lag In BlueStacks

In my experience with BlueStacks, optimizing resource allocation has been crucial for a smoother gaming experience. Whenever I encounter performance issues, I navigate to the Performance settings and adjust the RAM and CPU core allocation, providing BlueStacks with the necessary resources to run games seamlessly.

Moreover, the BlueStacks official support team replied to a person, saying, “Please try using the Pie 64-bit instance to see if this helps.” So basically, BlueStacks is suggesting reducing the version of the software as the only solution, but there are other methods they have included.

Graphics settings play a significant role in system performance. I’ve found that a quick visit to BlueStacks Settings > Graphic Engine allows me to effortlessly fine-tune the frame rate and resolution, ensuring they align with my system’s capabilities and contribute to optimal performance.

Virtualization is a game-changer for BlueStack’s efficiency. I make it a point to check and enable virtualization in my BIOS settings if necessary, as this enhances BlueStacks’ overall performance on my system.

Addressing graphics-intensive features is another strategy I employ. Disabling features such as DirectX and Hardware Acceleration in the BlueStacks settings proves effective in mitigating lag issues, allowing for a more fluid experience.

For older systems, Legacy Mode in BlueStacks Settings > Graphic Engine has been a reliable option. This older graphics rendering mode often provides better performance, and switching to Legacy Mode is a straightforward solution that I turn to when needed.

How to Fix BlueStacks Lagging (permanently)

Fix 1: Graphics Driver Update

In my experience, keeping my graphics drivers up-to-date is crucial for a smooth gaming experience on BlueStacks. I’ve noticed that outdated drivers can lead to performance issues and even crashes. I always make it a point to visit the official websites of Intel and Nvidia to download the latest drivers for both my integrated and dedicated GPUs.

Fix 2: BIOS/UEFI Update

Updating the laptop’s BIOS/UEFI firmware is something I’ve found beneficial. Manufacturers often release updates that address compatibility and performance issues. It’s been my experience that staying on top of these updates can contribute to a more stable system.

Fix 3: Power Settings

In my case, I’ve observed that setting my laptop to high-performance mode in the power settings makes a noticeable difference. Laptops tend to balance performance and power savings, and opting for high-performance mode has been effective for me in preventing unnecessary throttling.

Fix 4: Background Processes

Before diving into BlueStacks, I always make sure to close any unnecessary background processes. It’s surprising how much CPU and GPU resources can be consumed by other applications, impacting the emulator’s performance. This simple step has consistently improved my gaming sessions.

Fix 5: Compatibility Mode

Dealing with compatibility issues can be frustrating, but running BlueStacks in compatibility mode has been a helpful workaround for me. Right-clicking on the BlueStacks executable and adjusting the settings under the Compatibility tab is a quick fix that I’ve found to be effective.

Fix 6: Disable Full-Screen Optimization

Honestly, I disabled ‘Full-Screen Optimization’ for the BlueStacks executable. This feature, while designed to enhance performance, has sometimes caused issues for me. Disabling it in the Compatibility tab has resulted in a smoother overall experience.

Fix 7: Check for Game Updates

One thing I’ve learned is to always check if “The Tower: Idle Tower Defence” is updated to the latest version. Developers frequently release updates that address performance issues. Keeping the game up-to-date has definitely improved my gameplay, and I appreciate developers who actively work on enhancing the user experience.

Fix 10: Virtualization Technology

Enabling virtualization technology in the laptop’s BIOS/UEFI settings is crucial for optimal BlueStacks performance. It’s been my experience that without it, the emulator might not utilize resources efficiently. It’s a straightforward setting that I always make sure is turned on.

Fix 11: Check for Overheating

Overheating can be a silent performance killer. I use software like HWMonitor to keep an eye on the temperatures of my CPU and GPU during gameplay. If things start getting too hot, it’s a red flag for potential performance issues.

Fix 12: Antivirus Exclusion

Let’s be honest; antivirus programs can sometimes be overzealous. Adding an exclusion for BlueStacks in my antivirus software has become a standard practice for me. It prevents unnecessary interference and ensures that the emulator can run smoothly without triggering false alarms.

Identifying the Root Cause of Lag

Before diving into troubleshooting solutions, it’s crucial to pinpoint the underlying cause of the lag. Here are some potential factors to consider:

  1. System Specifications: BlueStacks demands adequate system resources, including RAM, CPU, and graphics processing unit (GPU). If your system is underpowered, it can struggle to run BlueStacks smoothly.
  2. BlueStacks Settings: The default BlueStacks settings may not be optimized for your specific system. Adjusting settings like frame rate and resolution can significantly impact performance.
  3. Background Processes: Background programs consuming system resources can hinder BlueStacks’ performance. Identifying and closing unnecessary programs can free up resources.
  4. Graphics Driver Updates: Outdated graphics drivers can cause compatibility issues and hinder BlueStacks’ performance. Ensure your graphics drivers are updated to the latest version.

Optimizing BlueStacks Settings

Step 1: Allocate More RAM and CPU Cores To Bluestacks

In my experience, adjusting the resource allocation for BlueStacks can significantly impact performance. I always head to BlueStacks Settings, specifically the Performance section, and allocate more RAM and CPU cores. This ensures that BlueStacks has ample resources to smoothly run games and applications.

Step 2: Adjust Frame Rate and Resolution

I’ve found that tweaking the default frame rate (FPS) and resolution can make a notable difference in performance. When my system seems strained, I go to BlueStacks Settings > Graphic Engine to adjust these settings according to what works best for my system.

Step 3: Enable Virtualization

Virtualization is a game-changer for BlueStack’s efficiency. In my case, I double-check my BIOS settings to ensure virtualization is enabled. If it’s not, enabling it provides a significant boost to BlueStacks’ performance on my system.

Step 4: Disable Graphics Intensive Features

Occasionally, certain graphics-intensive features in BlueStacks, like DirectX and Hardware Acceleration, can contribute to lag. Whenever I encounter performance issues, I promptly disable these features in the settings to ensure a smoother experience.

Step 5: Switch to Legacy Mode

Legacy Mode, an older graphics rendering option, has proven to be a savior on my older system. When facing performance challenges, I navigate to BlueStacks Settings > Graphic Engine and switch to Legacy Mode. It’s a straightforward solution that often results in improved performance.

Managing System Resources for Reducing Bluestacks Lag

To optimize your computer’s performance while using BlueStacks, you can try the following steps:

  1. Close any unnecessary background programs
  2. Reduce startup programs
  3. Update graphics drivers
  4. Optionally, defragment your hard drive to improve performance. 

Troubleshooting Persistent Lag

  1. Perform a System Scan: Run a system scan using your antivirus or security software to detect and fix any underlying system issues.
  2. Reinstall BlueStacks: As a last resort, uninstall and reinstall BlueStacks to eliminate any corrupted or outdated files.
  3. Contact BlueStacks Support: If the lag persists, consider contacting BlueStacks support for personalized assistance and further troubleshooting steps.
