Game stuttering CPU/Shader

Hi, im having micro lag /stutter despite the game always running bwtween 60-90 fps shader bar is always spiking while mappping and cpu often shows 15ms to 25ms while fighting...
cpu and gpu usage rarely goes over 50% for both and are running cool on temp

path of exile 1 and 2 are the only game that i have that much stuttering

What i have done so far :
-set power to performance (window and nvidia pannel)
-deleted all cache while cache limit was set to off
-set new limit to 100gb
-erased log--)client.txt

Computer specs:
CPU,12600k intel
GPU,5060 ti asus prime
RAM.16gb 3200mhz (xmp enabled)
windows 11

Game Settings:everything is set to low/performance
-dx12 or vulkan (tried both)
-Triple Buffering disabled
-Multithreading enabled
