I own an Asus N550JK laptop and I'm facing slow performance while gaming. My configuration is as follows:
- GTX 850M
I've recently started gaming again on my laptop after a long period of time playing only unintensive games. The games I've had the below issue with are Middle-earth: Shadow of War, Divinity: Original Sin 2 and Civilization VI (to a lesser extent). When I start playing, the computer heats up and my CPU starts underclocking (down sometimes to as low as 15% of maximum frequency). This causes the games to stutter. This is not a GPU issue as the games run at good framerate while the laptop is cool and the GPU doesn't underclock while hot. So far, I suppose, nothing really surprising.
What surprises me however is that the games don't always stutter. There is a specific case when sometimes they don't: when I start up the laptop from cold and open the game right away, I can sometimes avoid stutter even though the CPU overheats and underclocks. I can't explain myself why and am looking for an explanation. This would obviously allow me to keep playing even though the laptop overheats.
PS: any suggestion as to avoid my CPU overheating is obviously welcome too. Such CPU overclocking behaviour is only occurring when the discrete GPU activates and never does otherwise.
