only systems with WDDM 2.0-compatible GPUs show this information in the Task Manager. If you don’t see it, your system’s GPU probably uses an older type of driver.
You can check which version of WDDM your GPU driver is using by pressing Windows+R, typing “dxdiag” into the box, and then pressing Enter to open the DirectX Diagnostic tool. Click the “Display” tab and look to the right of “Driver Model” under Drivers. If you see a “WDDM 2.x” driver here, your system is compatible. If you see a “WDDM 1.x” driver here, your GPU isn’t compatible.
