POE 2 Complete PC Freeze while loading screen

Rolled back to 23H2. Still crashing, still getting freezes.

CPU reaching 100% usage during loading screens with high temps.

Unabelievable that GGG is blatantly ignoring this issue.

I have the same setup. I had posted a thread for this issue on Steam.

I was not aware that this was happening on POE1, because I don't recall it ever happening in my 260ish hours of playing (I know that's nothing compared to many of you all).

I am tinkering with some settings (no rollback, no disabling multithreading), and will let others know if game crashes or not.

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

PoEUncrasher worked for me as well, 4-5 hours and everytime it acts like crashing it saves itself, thank you Kapps

This is great, it automates the tricks I was doing to be able to play.

Well it took every initiative i had to play the game.

the game is a slog, it kinda runs ass too and then the freezes every 20 30 minutes ZZzzZZzZZzzz

Man next league will be good i hope...

The problem lies in the 3d cache from x3d AMD
Some people said they are having the crashes on other rigs which i think it is unrelated
every loading screen the processor goes to 100% usage
i tried on my old 9600k and played for over 3 hours without crashing
can't say the same about my 7800x3d
my friend has a 7950x3d and have the same problem.

And it's not only on Ryzen, there's plenty of intels here with freezings.

It seems that it helped when I turned off NVIDIA Reflex in the game settings.
Game settings -> Advanced settings -> Turn off NVIDIA Reflex.

I’m using an AMD Ryzen 7 7800X3D CPU, NVIDIA RTX 3080 Suprim GPU, and Windows 11 24H2.

This patch reduced the frequency it happens but still happens a lot.

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

Do you have any proof for that? How does it manifest, POE2 crashing or total PC lockup with 100% cpu and you cant ping the PC anymore on LAN? Both different issues. If that was true, it might indicate a more drastic issue with Ryzen architecture, which the new CPU scheduler of Windows 11 have shown to manifest because of better/perfect core utilization which was maybe already be true under Linux.

This might be the case for all (older) Intel CPUs with <= 8 cores. Even if a program uses 100% cpu, it should never happen that the total system locks up. The fact that the PC totally locks up means that the kernel has no CPU time left anymore (which is a bug in the scheduler and should never happen in the first place). So MS also needs to look into this.
