Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

I know I've spoken to you previously Galaticus, so I apologize if anything I say sounds redundant or if I suggest something you've tried already.

First, you mentioned that it first occurred when loading into a specific instance. Which instance was that?

Normally, updating your graphics card can help alleviate the issue. However for some graphics cards, it might be beneficial to revert them. Try doing a clean install of an older version of your graphics card drivers.

Remove any overclock that may be present on any part of your PC (this includes any factory overclocks on your GPU).

Have the game installed on the C drive if it is not already.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
