So, no... this is pure PR bs. I don't know if I'm right about this part, but the only case (that I can imagine) where a 64-bit processor would have any *major* effect on texture size performance is in a case where the textures exceed a 32-bit processor's 4gb limit. And, well, a 2048x2048x32 texture only takes 16 MEGAbytes, so we're a good ways off until it becomes a limiting factor.
Of course, 64-bit optimizations should be able to help in other cases, like geometry, AI, and physics.
Exactly. This is strictly a promo deal, the PR is...well, it's PR. Nuff said.
Not that the 64-bit version won't have additional performance - it might simply due to the added registers in the A64 - but it has absolutely bunk to do with increasing the texture quality. The shots provided indicate the 32-bit version has been crippled, rather than the A64 version being propelled forward due to "64 BITZ OF POWER11!!".
