Some of processes from before are actually using up more CPU than I previously posted
I've done some more digging and found out that DisplayLink is causing my iGPU to max out.
The steep cliff you see there is a simple game being dragged from a DisplayLink'd monitor to a hard wired monitor. Despite the game still running, the GPU's load drops steeply.
I can actually make the GPUs load go up to 40% just by moving my mouse left and right on a DisplayLink'd monitor with only static content on every screen.
I'm starting to believe the frame drops are from DisplayLink simply 100%'ing the GPU and it being unable to keep up.
In the logs you should see 4 monitors;
#4 is DisplayLink, running H1Z1 in Full Screen
#3 is DisplayLink, running Chrome (With this page open)
#2 is Hard Wired, running Task Manager and the support tool.
#1 is Hard Wired, and blank.
It is extremely easy to reproduce every single effect I have
Mouse lag, dropped frames, entire OS slowdown, and CPU spin up.
All I have to do is start playing video or a game on that monitor.
If you'd like I can repeat this process and gather logs for just YouTube or Netflix.
Extra information; This system has 2 GPUs,
an iGPU (Intel HD Graphics 530) and a Nvidia GeForce 980M.
