Not sure what happened recently, but Auto HDR on Windows 11 seems to have broken. It technically still enables, but there is no longer a pop up notification when the game starts.
Also with Windows Game Bar (windows key + G), going to the settings and then Gaming Features there is a button for "Adjust HDR Intensity" but its greyed out. It used to work just fine.


However with the Endwalker benchmark, Auto HDR is still working properly, giving a pop up notification when the game starts, and allowing the Adjust HDR Intensity slider to work. Why does it still work for the benchmark and not the main game? Is this going to break with patches?
