So my question is, in some games like Hitman 2, Rise of the tomb raider, all my 8 cores from my FX-8350 are at around 90-100%, obviously a bottleneck, and my GPU usage isn't at 99% but more in the 60-80% range, then there are games like Batman Arkham Knight, all far cry games etc... where my 8 cores are at around 40% usage instead of 90-100% and my GPU usage isn't 99% either but at around 60-80%. What's the reason for this? Why aren't all my cores being used to the limit in some games? Or a better question is, why isn't my GPU usage at 99% if my CPU usage isn't that high? I have the latest drivers installed, latest bios update and my temps are fine too.
