Fix 3: Update your network adapter driver

Reports show that lag spikes are quite common in NBA 2K21. But updating the network adapter driver can help you minimize game lags. Because chances are you’re using an outdated driver, which can negatively affect the networking performance.

To update your network adapter driver, you can either do it manually via the Device Manager or head to the manufacturer’s driver download page to download and install the exact driver for your system. This requires a certain level of computer knowledge and can be a headache if you aren’t tech-savvy. Therefore, we would like to recommend you use an automatic driver updater such as Driver Easy.

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.
