Some apps can also take over the Nvidia Global settings, even if it still says "Adaptive" in Nvidia Control Panel, and force maximum performance even when the app is not in use.
Downloading Nvidia Inspector and having a look in there might provide a clue. In Nvidia Inspector's "Global Driver" tab, you may see an app's name in brackets beside it. If so, that's the one that's taken over. May be a whole different thing altogether but I have a similar issue with an app.
It seems that you were right
In nvidia inspector my global driver tab had an app name next to it and the power setting was changed from adaptive to maximum performance and even if I changed it back it wouldn't go back to normal until I restart
I think I have figured it out now and it seems like it was because of that
Really appreciate your help
