[Find My Mouse] Refer to GPU usage to detect that a game is in progress

Description of the new feature / enhancement

Find My Mouse has a "Do not activate when Game Mode is on" option, but this does not work while playing games in the borderless window. (#14082)
I was using different software. That app was referencing GPU usage to determine game mode.

Can a similar feature be implemented in PowerToys?

Scenario when this would be used?

• It can determine if the game is being played in a borderless window or in windowed mode.
• Detection accuracy can be increased by combining with existing determination routines.

Machine learning models would cause this to not be a valid solution. There are other things that slam the GPU as well

[masukatto0281]

Opinion is correct. Machine learning was not considered.
It was inaccurate to base the decision solely on GPU usage.

@masukatto0281 Wouldn't the proper solution be to just use the Effective Power Mode API?

If the callback returns "EffectivePowerModeGameMode", then it's in Game Mode. Simple.
