Following up on the tread in case anyone searches this and is looking for answers. So I ended up getting a newer ssd samsung 860 pro, since the intel 320 series drives are a bit old, took out all other drives, installed windows 10, drivers, including nvidia driver without experience. Updated windows 10 fully and then Installed uplay and divisions 2. Played div 2 for an hour but instantly noticed much better performance. Installed msi afterburner with rtss and ran frametime and frame rate graphs. The graphs confirm that there are no more unusual frametime spikes for 40+ms.
So it appears either that I possibly had a drive going bad or there was software that was causing performance issues.
