you don't have to unlock anything, unlocking just lets the unlocked plan show up in windows power plan app. The utility should show changes, it shows each value for each plan (down left corner). But if they added a totally new power option, then the tool won't show it. Edit: yes your not going to see improvements in games as the video card is most likely what hold back fps in most games. One of the main changes of the Bitsum HP plan is to disable of parked cores, which would be more noticeable on a laptop/mobile which tends to cater to parking cores.
