Alienware laptops Underusing GPU

[Cybergenik]

HEEEELP ME!

Alienware 17 R4

i7-7700 HK

32gb RAM

GTX 1070

Windows 10 64bit

For some reason I noticed that after updating my laptop to the newest Windows 10 update, for some reason it will begin to under-use my gpu. Usually im running Overwatch at Low-medium settings at ~180fps only using %40-50 of my gpu. But then all of a sudden it will go down to like %6-15 usage and thus lower my fps to 20-30. I've been looking everywhere and the only thing i could find was that apperantly 2 months ago there was a windows update that fucked with Alienware laptops and that they where going to fix them. Is there anything I can do?

check the CPU and GPU temperatures first.

Check the nVidia Settings for Power Management mode, I had it switch to defaults after Windows 10 updates before which caused this issue (on a desktop though), had to switch it to Performance to prevent it happening.

 

Trouble is, that might be problematic on a laptop as its going to hammer the battery and maybe even slow the CPU by keeping the GPU clocked high all the time.
