True 32bit?

Dunno if this has been covered sorry if it has. When running 32bit apps in Vista x64, is it true 32bit or emulation? I am assuming emulation would result in a reduction in performance. Loss of performance using 32bit apps bothers me slightly but im more worried about the possible performance loss on running 32bit games. Thanks.

Windows x64 runs on the x86-64 instruction set as supported by the Intel Core 2 and AMD64. Unlike Itanium (which can't run Vista, I think), x86-64 natively runs both x86 (32-bit) and x64 (64-bit) instructions without emulation.

Does that mean your games will run as well on Vista x64? I can't say.

Thanks for your reply. Thats good to hear.
