I am wondering if my laptop is starting to thermal throttle. Here are a couple of pictures. At a couple points during the test, my GPU dropped down to 165MHz
Specs:
Msi Ghost Pro GS60 6QE (6th Gen CPU)
6700hq
16 GB DDR4
970m 3GB
Note that big drop on the left of the graphs is where I stopped the stress test and restarted it, but anything after the big gap such as those 2 second drops are actual results.
