Greetings Frogorius,

Thank you for providing us with the DXDIAG. To clarify, did you perform a full install of the game itself, or the GPU driver? If you have yet to do one or the other, I recommend fully uninstalling and reinstalling both. Other steps that I would taking to ensure you are running the game without any sort of possible interference are:

- Disabling or allowing appropriate exceptions for FFXIV in any anti-virus software you may have on the PC.
- Disabling any overlays or programs running in the background.
- Performing a clean boot by opening Task Manager, navigating to the 'Start Up' tab and disabling all applications listed. Restart the PC afterward.
- Turning off fullscreen optimizations. Find the game's executable file (normally in the install folder), right-click it and select 'Properties'. Select the 'Compatibility' tab. Check the box labeled 'Disabled Fullscreen Optimizations' and hit apply.

We hope this helps! Thanks again for visiting the FINAL FANTASY XIV Technical Support Forum.
