POE2 keeps freezing my computer

I was having similar Windows 11 problems with the game just crashing out with no error message after n minutes. Sometimes then repeatedly closing itself on game restart after the GGG intro, then working again.

Setting processor affinity to P-cores only did mitigate the issue. I was beginning to suspect processor failures after the recent Intel fiasco, and had installed firmware updates, no luck.

My ludicrious fix: 1) change no hardware, 2) install Linux.

Running flawlessly for me on Linux Mint via Steam and Proton. Same system that was dying repeatedly. No hardware changes. Did have lag after 35-40 minutes unless using controller, but turns out is a Steam input bug with an equally known workaround.
