How to Fix Alt Tab causes low FPS in games

When operating a computer with Windows on it, Alt-Tab is the more widely used shortcut to move between opened applications. But there were some Alt-Tabbing while running any games that resulted in lowering frames per second of their respective systems. These solutions would help you, in case Alt-Tabbing resulted in low frames per second of your Windows games.

The article will discuss fixing games on Windows that get a very low frame rate when an Alt-Tab option is tapped.

Try any of those that may work for you if pressing Alt-Tab on your Windows 11 or 10 PC causes your frame rate to drop while playing games.

Optimize your setup to be at its most efficient.

Turn off all startup programs along with the weather widget.

Try to start troubleshooting by performing a clean boot.

Uninstall any recent installed Windows Updates, if any, and then cleanly install the graphics card driver.

You should restart your computer.

The following is a detailed explanation of all these solutions.

1] Optimize your setup for the best performance.

You should first optimize your system for the best performance. Here are ways that can help you with the same:

Go back to the Settings menu of Windows 11 or 10.

Click on the System menu > About menu item.

Click on the Advanced tab in the system's settings. A window named System Properties will appear.

Settings icon in the Performance subtab within the Advanced tab.

Click the Adjust for optimal performance radio button.

Then click Apply, followed by OK.

After RAM upgrade on a Windows machine, the frame rate lags.

2] Disable the weather widget and all startup apps.

You should close any startup programs that you are not using to get the full potential of your computer. Press the Task Manager to end all the running processes. Keep all the windows that you are not using open as well.

At system startup, the startup apps run automatically. Therefore, you can disable them permanently so that they do not automatically start when the system boots. The other suggestion we may propose is turning off the weather widget. You can turn it on after you quit the game.

3. Restart your computer and try playing again

If the problem persists even after you disable the starting apps, it may be caused by a third-party background service. Just boot your machine into the Clean Boot state to see if it's there.

In the Clean Boot stage, use the Alt-Tab keys to launch the game. Just wait and watch. If the FPS remains constant, you need to identify the offending third-party service.

4] Clean Install Graphics Card Driver.

Another possible reason for this issue is a faulty graphics card driver. If that doesn't work, try updating to the most recent version. The manufacturer's website for your computer should have the most recent version of the GPU driver available for download. To install the most recent version of the GPU driver, run the installer file. Try reinstalling the GPU driver from scratch if that doesn't work.

Get the DDU tool and fire it up. Employ the usage of the DDU tool in Safe Mode to uninstall the GPU driver completely. As you have now downloaded the installation file of the GPU driver from the official website, install the driver from scratch.

5] If it applies, uninstall the latest Windows Update.

You can try uninstalling the Windows Update that's causing this if this began after installing it.

6: Shut down your PC

Perform a restore of your computer to its default settings to fix the issue. Ensure that your files are not deleted; it is possible by checking the option "Keep my files" while doing this. Although it does not delete data to choose this option during the reset of the PC, it is always a good idea to back up vital files before you proceed with a reset.

We hope that with this guide we can solve your problem and you will find many exits and good solutions.
