I got a GTX 1080 and R5 1600 @ 3.8 GHz so the CPU isn't the bottle neck, the GPU can reach 100% in graphically demanding loads like playing Forza Horizon 3 at 3440x1440p maxed out it will get 70-80 FPS with 100% load but if I drop it to medium settings it will stay at 70-80 fps but only have 70% gpu usage, this is the case in most games. I also have a 120 Hz monitor so it isn't VSync related. The CPU usage never goes above 40-50% and I'm not maxing out my RAM either. It also can't be an issue with drive speed as I have RAID 0 SSDs (900-930 MB/s reads)
Tried using graphics driver uninstaller tool and reinstalling the most recent drivers however that doesn't fix the issues.
Fresh install of windows about 2 weeks ago.
Suggestions welcome

No single core generally passes 60-65%

The GPU usage is sitting well below 100% usage as shown in the PUBG screenshot it’s running at only 50% usage when it should be trying to push more frames
