Done with latest drivers, few versions in fact, but nothing helped.
No crossfire, but 6990 is on dual GPU, not even sure how to disable one gpu - as said in previous post. So I'll leave it as it is.

Did the recreation of config/user files etc, crashing still...

And no the system's not overclocked.

I don't have a browser running when launching FFXIV so I doubt anything on my desktop will be using flash.

Nope, not trying something funny like windower or dual boxing ( I have problems running one, won't even dream of getting 2 of them now ).

Well I do hope 'they' see all these posts about 'crashes' in their official forum and address them in fact that was my intention of posting on official forums where it states "Technical Support". But thanks to all other members here for the advices though....
