Can anyone explain this high CPU/low GPU usage?

Hi,

Trying to play GTA 5 after a long time of not playing, and there's something very weird going on. I have upgraded to a GTX1080 from a 970 since I last played, so I bumped up a few settings in the graphics screen. I am definitely reaching 60fps, but it is quite stuttery, and I looked at task manager to find my CPU was at 100% and GPU was at 0.1% (on average).

My system is as follows:

i5 3570k at 4.5 GHz
GTX1080
16GB DDR3

I do not remember the game being this stuttery last time I played (around 2 years ago), the only thing that's changed in the system since is the RAM (went from 8GB to 16GB) and the GPU (970 to 1080). I play at 1440p as well. Here's a screenshot of task manager whilst playing.

Am I missing something stupid here? I'm also on the latest Windows 10 if that helps.

Cheers for the help both of you, I'll look into your advice, that Sleep Study stuff seems useful to know.
Task manager was open on my other monitor, which was PrtScn'd whilst I was playing.
Ryzen 3000 can't come soon enough it seems then

Wow fixed it, changing to fullscreen from borderless completely removed stuttering.
Seems Windows really doesn't like borderless mode recently.
