I think started noticing this problem after I updated to Windows 10 2004. Basically after I'm done playing a game, the discrete GPU (RTX 2060 in my case) should be idle. However PredatorSense shows its graph fluctuating between idle and non-idle (at 0% use). The Nvidia GPU activity icon in the notification shows the GPU is inactive, yet it's being turned on and off every few seconds, causing the system temperature to stabilize at 60 degrees C (usually I get about 45 degrees). I tried reinstalling the drivers, and downgrading to a previous Windows version, but the only solution I have right now is to restart the laptop.
