DirectX crashes

FFXIV pushes the GPU hard, You can use a program called RivaTuner Statistics Server to limit the frame rate to whatever you want. You can also use the task manager to see the GPU utilization, take the frame rate down so utilization goes to 85-90% and you'll probably also mask the problem. GPU is probably overheating.

My GPU temp always goes around 70°C when gaming , so its not overheating. Even without underclocking, the temp stays around that limit.

It might not be hitting the peak thermal limit but it might be hitting a thermal limit at that GPU load for that clock speed. I bet over volting will also fix the issue.
