A fatal DirectX error has occurred.(1100000f) - Only when Alt+Tab or Windowed Mode

Good afternoon,

I've recently come back to the game after a break, and I am able to play without issue on my desktop. However, when playing on my laptop, I receive the error "A fatal DirectX error has occurred.(1100000f)" when I start the game in Windowed mode, or when I try to alt-tab from Fullscreen. If I remain in Fullscreen, I can play the game without any issues. However, the inability to alt-tab, especially when I was able to do so without issue before, is concerning.

I have tried the following:
- A "Clean-Boot" (Disabled all non-essential processes and restarted laptop)
- Did a clean install of latest Nvidia Drivers
- Did a clean install of previous version of Nvidia drivers
- Ensured that Nvidia GPU is being utilized via the Nvidia control panel
- Reinstalled FFXIV
- Disabled all apps with Overlays
- Disabled Windows Game Bar and XBox Bar
- Switched to dx9 (This does resolve the issue, but I'd like to be able to use DX11)

Here is the System Info:

Good afternoon and thank you for visiting the Final Fantasy XIV Technical Support Forums.

When reinstalling the game, have you tried reinstalling it on the C drive?

Thank you for visiting the Final Fantasy XIV Technical Support Forums

Yes. Same issue. But to be clear, I've always had FFXIV on my D drive ever since I installed it on my laptop, and ran the game without issue until this most recent break that I had.

After several days of fiddling with my drivers, I've finally resolved the issue.

As my laptop has both an integrated and a dedicated GPU, there was an issue between the two communicating when "passing the buck" to the other. So switching from the Intel card to the Nvidia card had some sort of issue that was causing issues across a lot of my games. After trying to update the drivers on the Intel card several times without success, I tried completely deleting the drives via the Device Manager (Windows Key > Type "Device Manager" > Select Device Manager > Navigate to Display Adapters > Right Click on Intel HD Graphics > Select "Uninstall Device" > Follow prompts and restart computer) and upon reboot, my system reinstalled the Intel Graphics drivers automatically, with a new version (Old was from 2017, new was from 2018). After doing this, everything worked perfectly.

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

Thank you for keeping us updated. We will be moving this thread to "Closed Concerns".

Good luck with your adventures through Eorzea!
