I'd like to chime in as well. I've been getting this error reliably after 10-20 minutes of play, doesn't matter if open world or instanced area. Relevant specs are as follows:
AMD FX-6300 on a Gigabyte 990FXA-UD3 R5
Sapphire branded AMD R9 380
4x Corsair 4GB 1600 MHz DDR3
Nothing is overclocked at this point in an effort to remove possible causes of the problem.
The problem has been occurring again since the servers moved, but prior to this, I'd gone a few months without seeing the game crash like this. There are no other games in my library that crash in a similar manner despite placing a similar or heavier load on the system. I was initially under the impression the problem was with my computer, but
Solutions I've tried:
Switching to DX9. Usually works, but doesn't this time.
Reducing graphical quality settings. I get a higher framerate of course, but the game still crashes.
Reinstalling FFXIV. Doesn't help.
Disabling AMD-specific optimization in the Radeon Settings menu. I lose a few frames per second, and the game still crashes.
Disabling Spread Spectrum clock in my motherboard's configuration. No visible improvement.
Reinstalling Windows 10. Doesn't help.
