Stuttering and computer turned itself off

Starter playing today. Right in the first zone every 10ish seconds game would stutter/lag/slow down for a couple seconds. After a few minutes my whole computer turned off. Any suggestions on fix? Other games work fine.

Note: it was working fine on previous beta.

Laptop Nvidia Gforce rtx 3080 ti Intel i9-12950hx

EDIT: figured out the issue. I turned off NVIDIA Reflex Low Latency in Diablo settings. That fixed all my issues
