FPS drops, kinda random and very annoying...

I made a reddit post on my issue but I figured maybe the actual devs would have some other insight/advice and also could tell me which advice I can try following. As I remember the production_config.ini runescape mode (higher than 4) was actually a bad idea according to devs, while many people claimed it helped.

here is the link of the reddit discussion https://www.reddit.com/r/pathofexile/comments/8lr7q3/fps_drops_please_help_before_new_league/

and here is a screenshot

What happens is random fps drops, usually (if not always) at the very same time i experience a lag spike. However, if I run a pingmeter on the background he does not see any latency spikes, so it's not due to my ISP or bad connection. Or at least I can't see how ?

I also experience this issue plugged, and unplugged (even with a power control setup that provides always 100% power even if unplugged).

I have a gaming laptop (msi GL72m 7RDX) with a 128G SSD I added.

Specs are:

Intel Core i5 7300HQ

8Go of DDR4-2400

1TO SATA hardrive and 128Go ssd with windows and poe on it.

GeForce GTX 1050 with 2Go GDDR5

I use nvidia profile inspector to force 40fps (in order to bypass the screen lag when crossing 60fps, otherwise i am sitting at about 110fps in hideout but fps drops still happen even in HO doing nothing). I experience random huge fps drops as in the picture. I have no clue how to deal with those, and they are really making the gaming experience bad as for a fraction of seconds I am helpless and it sometimes (more often than not) ends up in me dying.

If someone has any clue on what to do to improve this I would be very grateful...

If there are some benchmarks or whatever I could do to test if everything is working correctly, please enlighten me (vaal or no balls). Drivers are as far as I can tell up to date and computer is rather clean both in software and hardware (I just openend it to undust it but it was surprisingly clean already).
