DirectX Crashing

[Rhaervis]

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

Have any changes happened to the device before the issue began? We would also like to recommend several other troubleshooting steps:

1) Make sure that your hardware is not overheating and remove any overclocks you may have on your graphics card or processor. Please check that any fans or vents are clear of blocks.
2) Disable any additional programs that could cause interference with the game itself including chat programs. Also, remove any custom configurations made using graphics driver-level programs
3) Remove any mods or injectors from the game or system
4) Turn off Fullscreen Optimizations. Find the executable file for the game (normally found in the install folder), right-click it and select 'Properties'. Under the 'Compatibility' tab, check the box labeled 'Disable Fullscreen Optimizations', then click 'Apply'.
5) Remove any unnecessary USB or audio devices (controllers, headphones, flash drives etc.)
6) Update and reinstall the drivers for your graphics card
7) Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything

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

I too am having this crash error pop up fairly frequently. Following the path you suggest C:\Program Files (x86)\Steam\steamapps\common\FINAL FANTASY XIV Online\game > ffxiv_dx11

When I right-click there is no "Compatibility" tab, only General, Sharing, Security, Previous Versions, and Customize
