C/GPU frequency problem

All versions I use, even other emulators like CEMU, met this problem.
I have an I7-7700HQ and a GTX1070max-q on my laptop, and for games like Overwatch, Rainbow Six Siege, they all can reach frequency 2.4GHz/900MHz for C/G.
But for every emulator I use, my CPU can only reach 1.7GHz, which causes great performance problem.
Any ideas what has gone wrong?

Set your OS power preferences to High Performance. Moving category to General.

how?
and thanks for moving
sorry to post with wrong tag

You can set via Power Plan Settings, i believe that Nvidia CP Power Management mode has also effect on that. but try one, the other or both. note that this will drain your battery faster.

seems nothing changed…
further more, I even can’t find ‘high performance’ mode
there are only ‘balance’
I tried to make a power management myself, but…
thanks anyway
