Open Windows graphics settingsĭoes this mean that NVIDIA's 'Preferred graphics processor' selection is now meaningless? Or does it only apply to non-UWP apps? Nobody knows. Windows OS now manages selection of the graphics processor. On latest Windows builds and NVIDIA drivers, the NVIDIA driver now shoes a very small warning notification: Microsoft is taking over the NVIDIA Optimus (MSHybrid) control from NVIDIA. Paint 3D just runs on Dedicated Graphics anyway. Set NVIDIA Control Panel to prefer Integrated Graphics.It just runs in the background without being asked. Just Reboot and hope that Paint 3D will be closed/killed.The following things do not help to fix this issue.

Set a profile for Paint 3D in Windows Graphics Settings to force Paint 3D to run on Integrated Graphics.

Disallow Paint 3D in Windows Background Settings from working in the background.

With those workarounds, the dGPU will go back to 'OFF' in Windows Idle. Apparently Microsoft thinks that system power consumption does not matter as long as you're plugged into the wall socket. The dGPU activity stops once you unplug the charger. You might ask: 'Who ever uses Paint 3D?' - well, I did. This apparently only happens after the first time you open and close Paint 3D on a fresh Windows install.

Paint 3D causes the dGPU to stay 'ON' by running in the Background forever, even after Reboot. Based on some user feedback and my own testing around XMG FUSION 15, I reported a new bug to Intel (Case 00534640), hoping they will forward this to Microsoft and get it fixed.
