I think a better way to solve this problem is to connect NVIDIA for help. We can keep gathering some more information and collect more reports while we wait to connect NVIDIA for help.
Does this change anything?
I think the second to last link states it pretty clearly:
- The display will not switch to discrete GPU in the following scenarios -
- The display will not switch to discrete GPU if the application in allow list is a DirectX9 application.
- The display will not switch to discrete GPU if there is a DirectX9 application already running. ...
- If any DX9 application is running and a display switch is triggered using the NV Control Panel 'display mode' settings page, the DX9 app could crash or freeze.
@miloush Yeah, but maybe Nvidia can fix it. And I test the empty wpf application with software render also can repro this issues.
Description
We have identified a recurring issue with applications developed using the WPF, which prevents the NVIDIA Control Panel from changing display modes on laptops. Specifically, when the WPF-based application (v2rayN) is running, the NVIDIA Control Panel fails to automatically switch between integrated and dedicated GPUs. This issue has been observed across multiple versions of the v2rayN application and various laptop models and configurations Attempts to resolve this issue by modifying hardware acceleration settings in the WPF application have been failed. https://github.com/2dust/v2rayN/pull/3493/files#diff-96773009aed874ddc50e8da8fb0d2a82ba83e862fb01c323de31a8e573bbadfdR203
Reproduction Steps
This is a minimal example of creating a WPF program without any modifications using Visual Studio https://github.com/2dust/v2rayN/issues/5255#issuecomment-2182387585
Expected behavior
It should not have any impact on the automatic switching feature of this display mode
Actual behavior
See a pop-up message in the bottom left corner saying "Unable to change display mode"
Regression?
No response
Known Workarounds
No response
Impact
Probably a laptop with an Nvidia graphics card and an integrated graphics card. Although my previous laptop also had this configuration (R7 5800H, RTX 3060), but there were no relevant settings in the Nvidia Control Panel and I couldn't test them
