Unable to detect DirectX device

[Micrll]

That driver is way out of date, so can I take your word for it that you actually have the most recent drivers? And that you ran driversweeper? This is the driver package that you want:

In any case, this isn't an abnormal issue.. and a driver crash usually has nothing to do with overheating in my experience. But the fact that FFXIV stresses your GPU to the MAX is a fact that is important to remember. You would probably find that a new card solves your problem.

This issue is further made noticable by the fact that if XIV looses sight of the graphics window even for a split second it throws the unable to detect DirectX device. Some other games would just hiccup and move on but XIV comes crashing down.

Might be a good time for OP to blow the dust bunnies out and increase the cooling.
