From what I can remember this has been a consistent problem since Endwalker has released. I'll log into the game and it crashes my GPU. As in, the game runs for a bit then my monitors go to black and say they have no signal, all sounds play in the background and from what I can tell everything functions except the video. I've looked around for multiple solutions and this seems like a problem that a lot of people have had with no fix. this happens to no other games I own. Here are some of the things I've tried to no avail.
  • Going into the properties of the game and disabling full screen optimizations
  • Removed any mods(I didn't have any in the first place)
  • Went into my AMD software and turned up my power limit
  • Deleted FFXIV.cfg
  • Played only in windowed( that makes it work for longer but eventually it crashes)
  • Ran nothing at all except XIV

I've really run out of options. here are my system stats:
  • AMD Ryzen 5 2600X
  • 16 GB Ram
  • RX Vega 56 8 GB
