Use Task Manager while the app is doing real work: its GPU Engine entry shows which numbered GPU and engine are active. Then open Task Manager’s Performance tab to match that GPU number to the adapter name on your PC. In Windows 11, you can also set an app’s graphics preference in Settings and verify the result afterward.
Check the app’s active GPU in Task Manager
- Make the app do the work you want to check. Load a game scene, start a video render, or play a video. An idle app may show no meaningful GPU activity.
- Open Task Manager. Press Ctrl + Shift + Esc, then select Processes.
- Show the GPU Engine column if needed. Right-click a column heading and enable GPU engine. This is a common interface route; menu labels and layout can vary between Task Manager versions. The click-by-click route is described in a Microsoft Community response.
- Find the app or relevant process. Read its GPU Engine value. It can identify a GPU number and an engine, such as 3D or video. Microsoft’s DirectX documentation on GPU reporting in Task Manager explains per-process activity and GPU engines.
- Map the GPU number to its name. In Task Manager, select Performance, then inspect the listed GPUs. Match the number in the process entry to the adapter shown there.
Understand what the GPU Engine entry means
The entry identifies the GPU engine doing work for that process at the time you checked; it is not necessarily a single, permanent answer for everything the app does. A process can use different GPU engines for different tasks, so check while the relevant work is active.

A low or zero 3D reading does not by itself mean the app is not using the GPU. For example, Microsoft notes that video playback can use a video engine without using the 3D engine: “playing a video under some circumstances may not use the 3D engine at all in which case the aggregated utilization on the GPU would have been reported as 0% while the video is playing!” — Microsoft DirectX Developer Blog.
Choose a preferred GPU for an app in Windows 11
If your PC has multiple GPUs, Windows 11 lets you set an app’s graphics preference. This preference is a request about power saving or performance, not a guarantee that every app will behave identically.
#1 Best Overall
- Axial-tech fans now feature a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- 2.5-slot design allows for greater build compatibility while maintaining cooling performance
- 0dB technology lets you enjoy light gaming in relative silence
- Dual BIOS switch lets you toggle between Quiet and Performance BIOS profiles
- Dual ball fan bearings last up to twice as long as sleeve bearing designs
- Open Settings > System > Display > Graphics.
- Select the app. If it is not listed, use the option to add or browse for a desktop app, then choose it.
- Select Options and choose Power saving, High performance, or the option that lets Windows decide, where available.
- Select Save, then close and restart the app.
- Check the process again in Task Manager while it is active to see which GPU engine is being used.
Microsoft’s Windows 11 graphics-preference instructions document this path and the restart step. The exact choices depend on the PC’s graphics hardware. These labels and screens are specific to Windows 11; do not assume the same path or wording applies to Windows 10.

On a system with integrated and discrete graphics, the choice is generally a trade-off between power use and workload performance. Integrated GPUs typically use less power and suit lighter tasks; discrete GPUs typically use more power and suit demanding work such as gaming, design, and video editing. Microsoft describes task-based GPU switching as a way to balance performance and efficiency in its GPU overview.

- Leave Windows to decide if you do not have a specific reason to override its choice.
If you cannot identify the GPU
- No useful activity appears: make the app perform the relevant task, then check again. An idle process may not show meaningful GPU use.
- The GPU Engine column is missing: use the column-header context menu in Processes to enable it. If the label or route differs, Task Manager’s layout may vary by Windows build.
- You see a GPU number but not a familiar adapter name: compare it with the numbered entries under Performance on that same PC. Do not assume GPU 0 is integrated or GPU 1 is discrete; numbering is device-specific.
- 3D utilization appears to be zero: inspect the process’s GPU Engine entry and consider whether the work uses another engine, such as video decode or playback.
