GPU 100 FPS drop

Howdy.In the past few months I've been experiencing huge FPS drops every now and then,which only occured a few times,but now they are really frequent.

I had no clue what could possibly cause this since the issue came out of no where,literally from a day to another.

I monitored my laptops performance with MSI Afterburner and noticed that whenever I had anFPS drop my GPU usage went from 60-80% to a 100%.

So basically whenever my GPU's usage hits a 100 my FPS drops.

I didn't notice any thermal throttling,when I play with the best settings possible my laptop is still at only 80-85 degrees celsius.

Also as far as I know it's not a CPU bottleneck issue.

All my drivers are up to date.

I didn't underclock/overclockanything nor undervolted.

My specs are:

CPU:Intel core I7 8750H

GPU:NVIDIA GeForce GTX 1060 6GB

OS:Windows 10
