Have a friend who always crashes in Delerium juiced maps like 3-4 times in say 4-5 hours. Has tried everything and still can't figure it out. Anyone have this same issue they were able to fix on PC?

Tried:
MTX
Disabling Engine Multithreading
DLSS
Swapping rendering off directX

Here for the answer. Same thing happens to me. My shader is constantly maxed whenever I run delirium.

This turned out to be someone using an xbox controller oddly enough.
