Massive FPS Drop in team fights?

[4k]

As the title says, gameplay overall is smooth and fine (roughly around 80-120 fps) but when a large team fight occurs, my frames can drop as low as 20!
I already tried diminish the graphics settings to the lowest possible (everything) but still the problem persists.

As far as my pc specs goes, i think it could be something to do with the processor (its 7 years old) i just don't know what the problem might be

i7 4770k
16gb ram 1600mhz
gtx1080 FTW 8gb
800w font

Hello M8,

I have some modest settings and my game goes well for all time of match.
i think the problem is the "unlocked" fps, as i have a 60Hz monitor i set it on 60fps
So i recommend you to do the same, if u have a higher refresh rate monitor, lock ur frame rate at the same as your screen

My specs

i7 2600k
16gb ram 1600mhz
RX 460 4gb
430w psu

Are MK present in your gameplay? Sometimes his ultimate can cause fps drop.

I have a garbage setup and my fps never dropped during teamfights, except when MK or Spectre's around.

actually it doesnt matter much the heroes present, it seems like whenever a lot of particle effects occur at the same time (5x5 teamfights where everyone is using everything they got in a rosh fight for ex)
its like my pc get a huge frame drop (spikes) and comes back to normal after its done.
this type of thing have only been happening recently *past 3 months* (i thought it could be a bad optimization change in the latest dota patches, maybe my Nvidia drivers needed to update but i tried updating/changing specs but even in the lower configs i get those insane frame drops.
(i always runned my configs in maximum, except for shadows that i keep at medium, DX11, 144hz Fullscreen exclusive and had no such problem) i mean sure, fps are supposed to drop when a lot of particle effects and whatnot happens in the game, but not so drastically as to from 90-120 to 15-20!
i'll try clean my pc as much as i can, and put some new thermal paste on my processor (i think it might do the trick cause i haven't changed/added more ever since i brought this pc about 7-8 years ago :x ) and if i succeed i'll let you guys know.

Ok, btw, i managed to stabilize my game now, by changing the "effects" option set to low instead of high. most everything is ON and on high except for shadows that are set to medium. hope that helps.
