GPU reaching 99% usage at just 700 mhz

[smoothpeanut22]

Hello Experts
I have a Gigabyte GTX 1060 GB graphics card I was having massive fps drops in all games so I decided to monitor what's happening and I found that my GPU was reaching 99% usage with just 700Mhz core clock and around 850mhz memory clock, that was a very strange behaviour from my GPU so I decided to do couple of things including a fresh installation of drivers using DDU, changing performance mode to prefer maximum performance in Nvidia control panel but nothing worked so after trying everything at last I stumbled upon to advanced 3D image settings in Nvidia control panel, and in there changing from "Let 3D application decide" to "use advanced 3D application settings" made it reach upto 1500 mhz but still having massive fps drops in all games that ran flawlessly in the past can you guys please suggest me something regarding this?(Note : I'm running windows 10 and it's up to date) Thanks in advance
My pc specs :
i5 7500, GTX 1060 6gb, Asus strix B250F gaming motherboard, 16gb ram and a 550 v psu

Okay I'll try to buy a new cooler so there's nothing can be done for the direct x 12? I've checked dxdiag and it says dx12 is installed but still the game freezes with dx12 when vsync is on, no matter if I choose Nvidia control panels vsync or in game

not until new cooler, wiping drive and reinstalling win.

after new cooler you can try installing Dx 11
