Frametime spikes

[Vikous28]

Hello so i have been experiencing these lags i had gtx 750ti and now upgraded to 1070ti and i was searching and i found out it is frametime spikes lag in graph in msi afterburner for some reason it is worst in among us when i like open task it will freeze for half a sec but fps stays the same 

so far i have tried :

Testing ram via memtest86, unplugging usb 3.0 some people had this solve they're problem, Ram from 3200mhz to 2133mhz, Allow cpu to boost over 3,6ghz in bios, unplugging internet via 'Check your network for rogue devices that might be announcing themselves on your LAN and causing your PC to do a hardware poll.', turn off windows overlay, nvidia overlay not allowing more than 140fps nothing has worked so far im desperate

This is my setup

AMD RYZEN 5 3600 

ZOTAC GTX 1070 Ti Mini

ASUS ROG STRIX B550-F GAMING (WI-FI)

G.SKILL 16GB KIT DDR4 3200MHz CL16 Trident Z RGB

Seasonic Focus GX 650 Gold

500gb ssd kingston 

if for some reason the monitor has to do something with it i have 24" AOC 24G2U/BK connected over dp

i will try ddu with old drivers and ddu with new drivers maybe try other mobo cpu psu. I also read that maybe because it is because of the electric grid which i doubt but maybe idk

If somebody could help me i would be very happy i spend goddamn 500$ on the gpu bcs of the market in our country and i cannot even play amongus without lags. Btw sorry if it feels kinda weirdly written im not from english speaking country
