Fatal DirectX Error 11000002

[Applesnap]

I've done broader research on this issue and managed to find an answer, sort of. The issue lies in Windows 10's Creator Update and how it forces Game Mode onto DirectX applications (even if you disable it). The cause of the crash, therefore, is a conflict between CU and the in-built streaming software of nVidia / AMD cards, respectively.

Perhaps something official posted with regards to info could help. I see a lot of people are having issues with this and are asking for advice on other forums.

Anyway, my solution was to:

• Disable Game Mode / Bar / DVR in Windows. (Search online for this.)
• Prevent Windows Update from automatically installing new versions of your drivers again. (FYI, it's not amateur-friendly).
• Revert back to Radeon suite 16.11.5 (last version without ReLive).
• You can enable GPU Scaling for your card, but it doesn't make a difference without the above changes. It's beneficial / non-harmful to enable it though, so may as well.

I lose access to both of my streaming applications (OBS 19 and AMD's ReLive -- I have an R9 380), but regain FFXIV stability at a slightly lower frame rate. Hasn't crashed once since I did all of the above. Mileage may vary according to your GPU but this is how I managed to "fix" it until Microsoft solves their CU issues.

Good luck! I accept no responsibility for broken PCs, explosions, apocalyptic events etc.
