How to fix Diablo 2/ Diablo 3 lags on Windows 10

  2. Run Diablo 2 in compatibility mode

  4. Update your computer/ game client
  5. Disable CPU-hogging programs
  6. Disable bandwidth-hogging programs
  7. Clean boot your computer

1. Update your graphics drivers

You have probably tried this, but let me say it again – make sure that you have the latest video drivers downloaded and installed. Indeed, such an old game doesn’t require too much, but just have this thing ticked on the to do list.

2. Run Diablo 2 in compatibility mode

Now, like any other old app or game, in Windows 8, 8.1, Windows 10 you will need to try and run it in the Compatibility mode to see whether it will work without lags, and will provide a smooth gaming experience. So here’s what you need to do:

  • Right-click the Diablo II icon and click Properties
  • Click the Compatibility tab and check Run
  • Select Windows XP (Service Pack 2 or 3) from the dropdown and then click ok

After that, you need to run the Video Test option under the Diablo II program listing, select Direct3D and after it loads, then click to patch to the latest version of Diablo 2.

After running the game in Compatibility mode, also make sure that you tick the following – “Reduced Color Mode” and “16-bit (65536) Color”. Also, you will need to disable display scaling on high DPI settings, just in case this has been missing with your game. And don’t forget to be logged in with an administrator account while performing all these changes.

3. Use 3DFX Glide Wrapper

If the issue still persists, you can try to remove the lags with 3DFX Glide Wrapper, which is a small application that could do wonders.

4. Update your computer/ game client

Your game client and all the games that you run on your computer depend on your device to run properly. Running outdated Windows versions may cause various issues, including lag issues.

Make sure that you’ve installed the latest Windows 10 updates on your device. Go to Settings > Update & Security > click on the ‘Check for updates’ button and install the available updates.

The same is valid for your game client. For example, if you use Steam’s gaming platform or perhaps, check for specific updates available for the respective clients.

5. Disable CPU-hogging programs

One common reason why you may experience game lags is represented by CPU-hungry apps and programs. If other third-party apps are using too much CPU and GPU resources, your computer struggles to run your favorite games.

As a result, turn off all programs that use too many resources so that your PC may direct them to your game.

  1. Go to Start > type ‘task manager’ > double-click on the first result
  2. Click on CPU to filter the results > right-click on the programs that are using too much CPU power > select End Task

disable high CPU programs

6. Disable bandwidth-hogging programs

Game lags can also be caused by bandwidth-chugging programs. Turn off all torrents, audio and video streaming apps if possible, close the browsers that you don’t need, etc.

7. Clean boot your computer

A clean boot starts Windows by using a minimal set of drivers and startup programs.

Here’s how to clean boot your Windows 10 computer:

  1. Type System Configuration in the search box > hit Enter
  2. On the Services tab >  select the Hide all Microsoft services check box > click Disable all.
