[SOLVED] Massive FPS drops, started around a week ago

[Planet_Noob]

Hey guys, I've recently been experiencing frame drops while gaming. I've tested it in several games, and it's been happening in all of them and started around a week ago (it's worked fine prior). For example in WarThunder, I'd get the FPS I'd normally get (~80), and then it would gradually start to drop to ~40. It'll then spike down to ~20 fps for around half a minute, and then go back to my normal FPS. It then repeats the cycle. My laptop specs is pretty much this and are as follows:
-CPU: Intel i7-7700 HQ
-GPU: NVIDIA GeForce 1070 Max-Q 8 gb
-RAM: x2 16 gb DDR4 @ 2400 MHz

Some things I've tried:
-Ensured computer was not throttling - it has been repasted and undervolted before and I've only started experiencing this recently
-Updated to latest NVIDIA drivers
-Rerolled and clean installed to previous NVIDIA drivers
-Set Window's power option to "High Performance"
-Set NVIDIA control panel's power management mode to "Prefer Maximum Performance"
-Set preferred graphics processor to "High-performance NVIDIA processor"
-Scanned computer for viruses/malware

I've also monitored these performance drops on MSI Afterburner and can be found here. The ~20 fps drops happens at the vertical yellow lines.

I have the exact same problme and tired these things as well. But still haven't found a resolution. One thing that helped me is using Afterburner I limited my GPU to not go above 1200MHZ, My rtx 2070 in Laptop goes to around 1550 MHZ AVG. So maybe you can try this. Just make a straight line in the voltage- frequency curve editor in after burner. to 1200MHZ. Here's how you can manipulate the voltage and frequency curve.
