PC Graphics

EDIT: seems to be CPU side, during normal gaming in game stats says CPU response/utilization is 7ms then it goes up to 50+ and stays there during stuttering

im playing poe2 via steam(and all its magic) on a fedora41

as the title states game runs superb(for minutes) then the game stutters heavily

i already undervolted and underclocked my gpu but the problem still persists (gpu temp at 60deg)
this happens in 1440p both in 144 and 60fps

pc specs
cpu: 5700x (cooled by peerless assassin mini)

gpu: sapphire nitro 6700xt

ram: corsair ddr4 8GBx2 (OC to 3200mhz) (passes memory stress test via stressapptest) (i could test via other apps if you have suggestions)
psu: cooler master 750 gold 80+ (mini itx version)

OS: fedora 41
gpu driver: MESA 24.3.4

game is installed in a 512 kingston ssd (not m.2 though)

attaching a video showing behavior and historical data from LACT
the GPU and MEMORY clocks dips down and then climbs up as the game stutters

update: issue also occurs in POE1

It was refurbished, but everything seemed new, even had the little plastic fils and all. It was bought in the biggest components shop in my country so this shouldnt be a problem, at least getting my money back.

Memory leak in game can behave like this. Fine for N minutes, then issues. How does system memory/vram usage look? I would monitor disk usage as well. Clocks might be dropping because it's swapping to/from disk.
