Thank you for the reply Kryptohaze.

If this isn't happening only when trying to stream and no where else, it seems as though the Geforce Experience app and it's streaming function is causing the issue. I understand that you want to stream the game, but if this is causing the game to crash, I'd recommend disabling it.

If you still wish to use the Geforce app to stream, I'd recommend doing a clean reinstall of your graphics card drivers and a reinstall Geforce Experience itself.

Also try disabling any other overlay and program that may be running while these two are.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
