Great now ill mark this as solvedThe same thing happened with me for rainbow six siege , keeping the resolution 1280x720 , that made my computer sleep even after applying the above settings
I found it was due to more fps , i limited my fps by turning on vsync in ingame settings
So that is also one of the solution for few games.
Try using AIDA 64 to determine hardware status like thermals while gaming.I had fixed this but i dont remember how.
Few people said that due to overheating its sleeping.
Im sure there was a 100% working fix for it because before clean installing my windows i had fixed this
