I played all day yesterday without a single issue. I did try all GPUS listed with the same problem happening. But I am no longer crashing as of writing this.
my changes
Limited gpu to 59fps (Radeon Chill limited the gpu, Card is water cooled 35c while limited, its just to limit fps on FFXIV)
Set ingame fps to 60 from 120.
Turned on Monitors Free sync to help tearing.
Set game to Window mode
Disable overlays, AMD game overlay, Discord, Steam just incase a issue was occurring.
I had previously removed all over clocks on the pc to see if this helped, It did not but I ll list that here as well as something to check
Which of these fixed it I ve no idea....I just know I don't crash anymore XDDD
GPU runs at less then 20% sometimes on FFXIV now, and cpu doesn't peak 5%. No crashes. Pc still plays every other game without needing any sort of changes like this, Only FFXIV required this.
I hope this helps someone!!! : 3
