Task Manager shows detailed information about the GPU

Thomas Rau

Since the Fall Creators Update, the Windows 10 Task Manager has provided extensive information on a system's graphics card. For example, you can see how much the GPU is being used for certain tasks - such as playing games or decoding a high-resolution video.

Because Windows gets this data directly from the graphics card driver, it is more accurate and up-to-date than if you installed a third-party tool. To call up the GPU information, first start the Task Manager: Then right-click in the task bar and select the command "Task Manager" from the context menu. Click on "More details" and then on the "Performance" tab and in the left column on "GPU". In the heading on the right you can now see the model name for your graphics card. If there is no display for the GPU, it may be due to an outdated driver: Only drivers that at least correspond to the Windows Display Driver Model (WDDM) 2.0 will also work with the new Task Manager display. You can see the WDDM version of the currently installed graphics driver in the Dxdiag tool in the "Display" menu and in the "Driver model" box on the right in the "Driver model" line. The task manager shows the utilization of four functional units of the GPU as well as the memory usage.

These units include, for example, 3D rendering, video decoding and encoding. Other units can be displayed by clicking on the name of the currently displayed unit and selecting another unit from the drop-down menu.

As the total workload under the four boxes, the Task Manager always shows you the workload of the currently most busy functional unit, and not the sum or the average of the selected GPU units. Below you can now see the memory usage, to the right of this is broken down according to the usage of the local graphics memory of the GPU and the shared memory: This is the portion that the GPU gets from the system RAM. If these details are identical, you have a GPU unit that is integrated in the processor and does not have its own memory. In the case of a graphics card with local memory, you will always see half of the main memory in the computer when specifying the shared memory, because Windows only assigns a maximum of this proportion of the system RAM to the GPU. For a system with 16 GB of RAM, this is 8 GB. You will also find information on the version and date of the installed driver and the DirectX version used by the driver in the information in the Task Manager.

EnlargeWindows can only display the GPU information with a current driver: Check the important information about the driver model in the Diaxdiag tool.

The GPU information can help to track down certain graphics problems: If, for example, Full HD videos or, above all, UHD video streams jerky when playing on your system, then it is worth taking a look at the information in the Task Manager. Now play the corresponding video and pay attention to the load on the decoding unit of the GPU: If you only see a small load or no load at all, the GPU is not involved in this task; the CPU is probably the only one doing the decoding of the video material. This can be checked by taking a look at the “CPU” section in the left column of the Task Manager: If the displayed processor load increases when the video is played, the CPU in particular has to take over the decoding task. An older processor can then be overwhelmed with the playback of a high-resolution video and the film can therefore not be played smoothly. In this case, you can check whether there is a possibility in the playback software to activate the hardware acceleration of the GPU - if the graphics card can decode the corresponding video format, the video playback should run smoothly, since the GPU is better suited for this task than the processor .

Tip: Over time, the computer becomes slower and working with the PC becomes less and less fun. Time to take a closer look at the computer to see what is slowing it down. We provide you with 45 top tools with which you can tickle all information out of the system and which help with optimization.
