Greetings Adventurer!

We would like to assist with your concern. Please try the following to see if they help:
- Try switching to DirectX 9 or DirectX 12 (If you are able to) by selecting the ‘Config’ button on the launcher.
- Update and reinstall the drivers once more for your graphics card and sound drivers (The graphics drivers were last update 09/11/2023. Just to be sure, check if any updates are missing).
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Please be sure to disable or remove any overlays (Discord, Steam, NVIDIA etc.) as they may interfere with startup.
- Make sure that the Windows OS is fully updated.
- Install game on different drive. (If Steam version, make sure game and Steam are installed on same drive).
- Reinstall game (If steam version, try uninstalling and reinstalling both the game and steam).
- Verify installation files (If playing on Steam).

If you do not see an improvement, please feel free to respond to this thread for further troubleshooting.

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