ASUS FX504GM Incredibly Poor Performance

[SatanExe]

I have the ASUS FX504GM-EN151T.
Here's a summary of the specs:

• Intel Core i5-8300H
• 8 GB RAM
• 1 TB HDD
• 256 GB SSD
• Nvidia GTX1060 6 GB

However, when trying to play even the most simple games, I get extremely poor framerates.
I get ~160fps with common spikes on CSGO on minimum settings.
I get ~80-90fps with fairly bad 1% lows (haven't measured, but it feels like 30fps) even on MINECRAFT.
On Overwatch, my average framerate is around 75fps on lowest possible settings (still 1080p though), and feels even laggier with constant stuttering.
I've undervolted my CPU and turned off the TDP limit using Throttlestop, but it still says I'm PL2 EDP Other throttling. I've also updated the BIOS firmware. 
Has anyone got any advice? At this point I'm extremely close to just selling the laptop and buying a lower spec one that will perform BETTER.

could you do a userbenchmark test? then i'll look at it tomorrow if I have some time. it might just be that you're running on intergrated graphics or heavily thermal trottled by a bad application of grease.

 

i'll add @GeneXiS_X here too

This model is infamous for its aggressive throttling (CPU and GPU) to keep temps down due to bad cooling solution

 

Try undervolting GPU (guide in my sig below), set Speedshift to 1 and disabling BD Prochot (use Throttlestop). Also try repaste
