Greetings,

I can confirm these issues, 'appcrash' & 'BSOD' are affecting Windows 8.1 (64 bit) as well as 7 (64 bit). I have been experiencing the same issues since launch, although never had a problem in Beta.

I have followed this discussion and tried both the straight forward suggestions of OS re-install & Game reinstall, as well as trying at least 10 different sets of videocard drivers for my AMD HD 6950 both official & Beta, combined with trying tweaks and other settings adjustments which seem to have helped other players with no success.

Consequently I invested in Win 8.1 hoping this may overcome the issues which only seem to affect FFXIV, it doesn't happen when playing any other cpu/gpu intensive games. Initially it did seem to be gone, but once again after the most recent maintenance it seems to be occurring again.

I don't know if there is any relation between maintenance patch's and a increase in this issue occuring, but it does feel this way especially after changing to Win8.1 & playing for many days without a BSOD until today.

While there doesn't seem to be any isolating factor to group all players affected, as this is affecting both AMD & Intel CPU's and both AMD & Nvidia Videocards and as mentioned most operating systems it does appear a common link in the responsible module failing and causing the crash's relates to DirectX libraries d3d9.dll etc.

I like everyone else have tried everything I can at "user level" and simply hope SquareEnix can identify the issue and either announce what we need to do at our end to fix it, or fix it at there end. As the unstable nature makes playing dungeons etc. in this game impossible... as everyone else following this thread understands.

Just one more sad face.
