Consequently, more and more people are trying the game on their PC, laptop, or tablet. However, recently, many players have complained about Hearthstone lagging on Windows 10.

Of course, we want you to continue playing the game without any hassle. As such, we’ve put together this article to teach you how to fix the Hearthstone lag issue. Make sure you work your way down the list until you get rid of the problem completely.

Method 1: Ensuring that Your Computer Specs Meets the Minimum System Requirements For the Game

It is possible that Hearthstone is performing poorly because your PC does not meet the minimum system requirements for the game. It is best to check if you have the right operating system, processor, graphics card, and RAM. So, the first step on learning how to troubleshoot Hearthstone lagging is to check the details below:

Operating System

  • Minimum Requirements: Windows XP, Windows Vista, Windows 7, or Windows 8 (latest service pack)
  • Recommended Specs: Windows 7, Windows 8, Windows 10 64-bit (latest service pack)
  • Processor
  • Minimum Requirements: Intel Pentium D or AMD Athlon 64 X2
  • Recommended Specs: Intel Core 2 Duo E6600 (2.4 GHz), AMD Athlon 64 X2 5000+ (2.6 GHz), or anything better

Graphics Card

  • Minimum Requirements: NVIDIA GeForce 6800 (256 MB), ATI Radeon X1600 Pro (256 MB), or anything better
  • Recommended Specs: NVIDIA GeForce 8800 GT (512 MB), ATI Radeon HD 4850 (512 MB), or anything better


  • At least 4 GB RAM

If you want to know your computer’s specs, you can follow the instructions below:

  1. Press Windows Key+R on your keyboard to launch the Run dialog box.
  2. Inside the box, type “dxdiag” (no quotes), then click OK.
  3. Now, go to the System tab and check the details regarding your PC’s operating system version, processor type, and memory.
  4. You can go to the Display tab to check what graphics card you have on your computer.

If you find that any of your PC’s specs do not meet the minimum system requirements, you need to upgrade your hardware to be able to play Hearthstone without any issues.

Method 2: Updating Your Graphics Driver

One of the common causes of Hearthstone lagging on Windows 10 is an outdated or corrupted graphics driver. So, if you want to resolve the issue, you should try updating your graphics driver. Now, you should know that there are three ways you can do this:

  • Using the Device Manager
  • Downloading and Installing the Drivers Manually
  • Using Auslogics Driver Updater

Using the Device Manager

  1. You need to launch the Run dialog box. To do this, you must press Windows Key+R on your keyboard.
  2. Inside the Run dialog box, type “devmgmt.msc” (no quotes), then click OK.
  3. Now, expand the contents of the Display Adapters category.
  4. Right-click your graphics driver, then select Update Driver from the list.

Downloading and Installing the Drivers Manually

When you use the Device Manager to update your graphics driver, there’s a possibility that you’ll miss the latest version of the driver. So, you might still end up downloading the driver manually from the manufacturer’s website. When you choose this method, you need to ensure that you are downloading the right version for your operating system and processor. Remember that installing an incompatible graphics driver can cause bigger issues.
