List of things done with fresh install; note that all installers were installed via right click / run as admin and came either from OEM drive and then updated or came from main website ie nvidias driver site.

#11 Installed CommandControl_Ver_2.9.0 (rebooted after install); i hate this software, i hate that it's forced to be the front window, i hate that without it i can't have my full brightness on screen ???? and that my FN keys dont work in full without it.

#19 Installed Drivers_Update_v1.7.2 (Rebooted after install)
#20 Updated all of the above, rebooting where neccessary ( thought i would save you an extra 20+ steps
. )
#21 Updated keyboard firmware.
#22 Installed XTU ( rebooted ) see screenshots below
#22.1 Image is of main page on boot up ( mains power)
#22.2 Image is of advanced tuning page ( mains power)
#22.3 is of advance tuning page seconds later whilst on battery
#23 Signed into geforce experience and updated drivers.
#24 set steam up and linked library to my hdd with witcher 3 installed on. ( my test game for throttling ect )
#25 set witcher 3 settings to ultra preset and started to do a run around the bloody barons castle on mains power. See XTU screens below.
#25.1 this is after 3 minutes of running around area mentioned above on mains power.
^^^ < This is acting slightly different than it was before, on mains i never got this. But now i do....
#26 Repeated the same test at the castle but this time on mains power. I have done two 3 minute intervals here
#26.1 First interval has around 30 seconds of cutover from mains. ( you can see the throttling as i take the cable out )
#26.2 Annd......... yeah.
And that is where i left it. I am now writing up this post. The current limit throttling appears to be the big hitter so would love any input here. If you think anything needs to be uninstalled / changed ( such as command center as im sure that fiddles with cpu overclock and such but am not sure what or if it overrides.
So sorry for the image heavy post. Just wanted to provide as much info as possible.
Cheers
