Thank you once more for the further response.
No, as far as I can recall even before I upgraded this rig to its current specs listed above I've always had issues trying to play FFXIV without at least a few crashes a day.
I've attempted the steps you mentioned and nothing has helped, I am still getting DX11-related crashes after a certain amount of time playing. Are there any other suggestions you can list or am I doomed to not be able to play on this computer?
Thanks.
