Stability Issues with Path of Exile on Intel 13/14th Gen CPUs – Multithreading Workaround Needed

Hi all,

I wanted to bring up a recurring stability issue I’ve been experiencing with Path of Exile on my high-end setup featuring an Intel 14th Gen CPU (i9-14900KF specifically). The game frequently crashes or closes automatically within seconds of launching, with no error messages. Before todays update, i had crashes but nothing like that as today, i couldn't even reach the character selection screen and the game would close, no errors, nothing!

After extensive troubleshooting (clean reinstall, driver rollbacks, disabling overlays, etc.), I discovered that the problem seems directly related to how PoE handles multithreading on these latest CPUs.

What I found:

By manually setting CPU affinity in Task Manager to restrict PoE to just one core, the game becomes stable and no longer crashes.

Disabling multithreading or limiting the game to a single core resolves the issue.

This suggests PoE’s engine may have compatibility or race condition problems with the new CPU architectures and their aggressive multithreading.



Many players as me, now have high core-count CPUs, and being forced to limit PoE to one core hurts performance and user experience. I haven't paid so much money, on a gaming pc, to enjoy the games i love, only to find out that the pc i have is too much for those games to handle.
PoE’s multithreading and CPU scheduling should be updated to fully support modern CPUs without crashes.


Please investigate this multithreading compatibility issue on the newest Intel CPUs and consider updating the game engine or providing official guidance/workarounds to help players avoid crashes without sacrificing performance.

Happy to provide any logs or testing info to assist.

Thanks for your time!

Well there is a Problem with the 14th Gen Cpus i also have a 14700 kf but more in Temps/Load but i dont have any Crash the Game runs the whole Day and i dont have any Error or Shutdown. Have you updatet your Mircocode?/Bios Update?
