Rereleasing FFXI

[Mirage]

It's not as easy as "giving it" the entire CPU, though. If you take away the graphics part, a single core of a modern PC would be way more than the game would ever need. The only reason why FF11 is very CPU dependent is that practically all the 3D rendering is happening on the CPU as well, not on the GPU where it really belongs.

If the game did the 3D on the GPU like every other game in the world, the fact that it only uses a single core would be of no significance, because apart from the 3D, the game uses very little CPU power.
