Fatal directx error 1100000f every time game is launched - unable to play

[Gothicshark]

I had the same issue with a 2080 machine, I did all the recommended fixes, and trust me the list of things to fix it is huge, in the end I went back to my older machine, and everything is fine. The problem here is only FFXIV has an issue with graphics cards, and for some random reason it affects a small handful of us and Square seems unable to fix or actually identify what is causing it.

However to disable the onboard graphics card which is something to try, find the make and model of your Motherboard and find the Bios updater for it from the manufacturer. Because it sounds like it is due an update if you can't find the advanced settings. (Which is odd IMO, as even the most annoying manufacturers add those to their bios.)

List of Fixes I have seen, and tried.

• Run the Game in Borderless Window
  
• Run FFXIV Using DirectX 9
  
• Rebooting the PC
  
• Updating my graphic drivers
  
• Doing a clean reinstall of my drivers
  
• Setting the game to full screen then back to borderless a bunch of times
  
• Disabling all applications that could maybe have some kind of hidden overlay
  
• Closing every possible application before running FFXIV
  
• Physically cleaning the dust out of my PC
  
• Disabling various settings related to Windows Game Bar and other notifications
  
• Deleting the Final Fantasy XIV folder in My Games (don't worry, I saved the screenshots)
  
• Rolling back a few Windows updates
  
• Reinstalling Windows using the "Reset this PC" option
  
• Reinstalling FFXIV after the reset
  
• Undervolting GPU
• Disabling SLI (this computer had a similar issue with other games but it was due to SLI)
