POE 2 Complete PC Freeze while loading screen

I tested the program https://github.com/Kapps/PoEUncrasher/releases/ on 24h2 with Ryzen 7800x3d CPU and can confirm it also works by automatically setting CPU affinity by -2 (or more) cores during loading screens of POE2 to prevent total PC lockup.

Also since the new version 1.2.0 it automatically unfreezes POE2 process with a trick setting POE2 to realtime for a short period of time during the stuck.

From the autor of the program:

"Found a workaround that allows PoE to recover after it freezes. Previously while your computer wouldn't freeze, PoE still would. I noticed though that setting PoE to realtime priority allows the threads that are stuck to get scheduled again and resolves it. This new version sets PoE to realtime priority if it detects that it freezes, and then sets it back to normal after the loading screen. Note that you will need to run the program as an administrator to be able to get PoE to unfreeze."

This confirms what I already said from the beginning: The root cause is a bug in the Windows 11 24h2 CPU scheduler (which was also back ported to 23h2 with an optional update). It might also be true, that the issue existed already before, but does not manifest in general and the new scheduler manifests it because of utilizing the CPU better under full core usage.

I wrote an email to MS developer to look into this.

People on 23h2 who also have the issue need to see if they installed the optional update kb5041587 and remove it

Its not a windows only issue, I have the same with my 7950X3D on Nobara.

windows defender was checking the shader cache everytime while it was created during the loading

This is the way!! Game is way smoother.

This is probably the most underrated solution! I confirm, the problem is gone and the loads have become very smooth! Some time ago, I noticed that Windows Defender started very aggressively checking new files and loading the processor. POE 2, when loading locations, creates many cache files in this folder, and the defender starts actively checking them, somehow overloading/breaking the system.


I recommend everyone to check this solution!

HOLY HOT TURTLE DOOKIE!

So i've just tried this method. I can tell you this is the best PoE2 has run from since this whole nonsense. Even doing the affinty fixes, power plan etc etc. My CPU would be instalocked to 80%%. would be 100% with out the affinity.

I have not even tried to do the affinity fix. After doing the exclusions. I'm hovering aroud 40-50% cpu usage.
