I'll try to get a visual example later today.
There are no real patterns to the crashes as far as I can tell, they kind of just happen very suddenly for no reason.
When it first started happening I thought it was a driver issue, completely erased my drivers and installed a fresh one, no change. Maybe it was a corrupted FFXIV file, completely uninstalled, deleted everything, reinstall, no change. Maybe it was my DX11 itself that was bugging out, so I did a fresh reinstall on that as well, no change.
