How to Check that Your Graphics Card Is Being Used

If you have installed a new graphics card and updated its drivers, you should verify that the hardware is being used properly. If your display cable is linked to your motherboard instead of your graphics card, your graphics card will be ignored. In addition, it may result in Windows defaulting to using software acceleration for visual effects.

Using the Windows Task Manager, you may verify if this is the case. To open the Task Manager window, right-click the taskbar, press Task Manager, and select the Performance tab. Devices with multiple GPUs (such as PCs with an integrated GPU on the motherboard and an external graphics card) will be displayed here and labeled GPU 0, GPU 1, etc. If the internal graphics chip is using more resources than the graphics card, your graphics card is not being used. Ensure that the suitable device is being used by inspecting the connections between your Monitor and the graphics card.

Scan Microsoft Windows for Malware

High CPU usage may indicate a malware attack if your system is up-to-date and functioning properly. Be careful to make a complete malware check on Windows 10, including a boot-level scan with Windows Security or another antivirus program.
