64-Bit and DirectX 11

[Wildsprite]

clearly have no idea what you're talking about. A 64 bit client handles memory virtually no differently than a 32 bit programme.

A 64 bit based programme simply handles more bits at once allowing for a slightly faster and less time consuming computation, but at best this is minimal.
FFXIV currently isn't struggling to process information, therefore a 64 bit client is simply unnecessary for the most part.

It could be done, but it isn't needed and the difference wouldn't be noticed by the vast majority (contrary to what you seem to think)

A 64-bit client would mean virutally nothing for FFXIV:ARR, please do your research on this before making baseless assumptions.

its safe to assume you dont really know the technical aspects of computing if you believe a 64 bit client wouldnt handle memory different
64 bit computing handles memory in 64 bit MEMORY chunks, it takes twice as many passes for a 32 bit program to do the same. you are right that some wont notice a difference but those people are on very high end PCs to begin with.
why don't you do your research before trying to take apart my argument.
there are more 64 bit computers out there than there are DX11 computers.
and even then most of the DX11 computers that would benefit from a DX11 client are high end PCs. there are low end DX11 PCs you know and DX9 is faster on PCs period even if you dont realize it, DX11 like DX10 only adds eye candy very little processing power. if you want a framework that adds both you need to go with OpenGL
DX11 is not all that despite what you want to argue and DX9c is not that far behind it because MS kept updating it due to how many people outright refused to upgrade from windows XP
