Hard crashing PC locks up

I have had some good success with an app called Process Lasso. You can use this to specifically set a rule for the PoE2 process to drop to IDLE priority and unassign 2 cores if the CPU usage rises above 95% for a second, and then remain at IDLE for say, 10 seconds. And then resume normal processes.

Find the tool here: https://bitsum.com/

To do this:

* Open Options, CPU Limiter
* New CPU Limit Rule:
Process match: pathofexilesteam.exe
When CPU use is: 85%
For a period of: 1 seconds
Reduce by this many cores: 2
For a period of: 10 seconds.

I also use ProBalance settings:
Advanced/
Leave all settings except:

Lower to idle priority instead of below normal: Ticked
Ignore all foreground processes: Unticked
Change affinity during restraint: Ticked
CPUs: 2-15 (or how many cores you have, just ensure you start at core 2)

This has immediately solved the issue for me - and it even decreases load time dramatically as well. Any tool that can reduce the CPU priority and remove cores will probably work, but this can be done on a rule basis per running process.

Of course, I cannot say if this is guaranteed to work for everyone. But I can say I've had hardlocking constantly, and I've now been able to play for 5 hours continuously. Except for one REALLY off bug that may be a server issue (says my controller is unplugged then dumps me back to the login screen).

FYI: No "solution" here will ever fix the issue. The only true solution is disabling multi-threading. To lessen how bad the crash happens, you can disable CPU cores on the process so it only freezes the game and not your PC. Nothing else will help.

Claims saying it's 24h2 are untrue as well. It happens on older versions of Windows as well.

This is an issue with their async thread code resulting in memory violations. It causes an infinite loop trying to read an invalid pointer when loading new levels, which never completes so just eats performance. The reason why disabling some CPU cores works to not cause a complete crash is because processes do not all share the same threads on those cores. Likely if you disable CPU0 from POE2, Windows core functions will have some headspace on main to work with so you can end the process from taskbar.

Open Nvidia Control Panel Open 3D Settings
Go to App specific settings, choose POE (64 and the other)
At the bottom of the list change the Vulkan/OpenGL thing to DXGI Swapchain
In game, change DX12 to Vulkan

Crashes are gone. No need to mess with SMT or Process Lasso
