Fix 3: Update your graphics driver

When the lag issue appears, it may indicate that you’re using an outdated or faulty graphics driver. GPU manufacturers frequently release new graphics drivers that usually give major performance improvements and fix some bugs and glitches. So in order to enjoy your game to the fullest, you should check for graphics driver updates.

There are mainly two ways you can update your graphics driver: manually and automatically.

Option 1: Manually update your graphics driver

To update your graphics driver manually, you can go to the official website:


Then find the drivers corresponding with your Windows version and download the drivers manually. Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the drivers.

Option 2: Automatically update your graphics driver (recommended)

Fix 4: Temporarily disable background programs

If your computer runs several resource-hogging applications in the background, your game will be more likely to be laggy. What’s more, they are consuming your bandwidth, which you need for your online gaming. So to minimize your game lags, you need to stop apps from running in the background.

1) On your keyboard, press the Windows logo key and at the same time to invoke the Run box.

2) Type taskmgr and press Enter.

3) Under the Processes tab, select the programs that are CPU-intensive. Right-click on them and select End task.

Once you’ve disabled programs running in the background, launch your game to check if it’s still lagging.

Fix 5: Temporarily turn off Windows Automatic Updates

Although you need to keep your computer up-to-date, there is nothing wrong with turning off updates for a moment. The updates could sabotage your bandwidth and will likely cause lag in your game.

Here’s how you can temporarily turn off Windows Automatically Updates:

1) In the Search box, type windows update. Click Windows Update settings from the results.

Fix 6: Use a wired connection

If you’re using Wi-Fi or wireless connection on your PC, it’s time for you to see if a wired connection will improve the situation. To do that, use a LAN cable to connect your device to the router and restart the game to check if it resolves your issue.

Fix 7: Change in-game settings

By tweaking the game settings in the options menu, you’ll see a positive difference. To do this, follow the instructions below:

1) Select FEATURES.
