x17 R1, gpu usage stuck at 60/70%

So finally laptop arrived, was working great, only installed mi dia GeForce experience and then updated the grafic drivers and was working great, 70/72 degrees, 140watt and 98/99% gpu usage, in battlefield 2042, then, don’t ask me why, I watched a dell guide video on how and what drivers to install, then followed the procedure and the dell website with the assistant downloaded and installed some driver, between which there was also an other nvidia driver, after that the gpu won’t go over 60/70% usage, both on laptop display or on external display, having the 1080p 165hz without mux switch, so, angry as I was I did a fresh install of windows, deleting everything, windows 11, again installed only GeForce experience and updated driver but this time didn’t used the dell assistant for driver, but gpu is still stuck ad 60/70% usage, cpu doesn’t seem to be a bottleneck, cause ingame it won’t go pass 40/50% utilization, please help, brand new gaming laptop, can’t accept that the gpu is working at almost half it’s performance, and the thing that is killing me the most, is that before following dell procedure the laptop was perfect, so dell, fix the problem you created, thanks

configuration: i7 11thgen, rtx 3070 140watt, 32gb ram xmp 

ps: already setted all power setting for maximum performance and obviously was using the power brick, so I really can’t understand what’s happening
