It's very simple you take a huge loss running 32 bit apps in a 64 bit OS, as the OS has to run double the work now running a 64 bit app and a 32 bit at the same time
I'm sorry I don't want to get involved in another argument Dan but that is completely Wrong.
WOW64 is native Code and the 32bit instruction sets run native on the modern X64 cpus, the only exception being Itanium cpu's which don't have a full x32 instruction set, therefore some of it is emulated (At a very low level!). As I don't think many Reaper users are running IA64 systems, there is no hit running on WOW64.

Even doing real hard OS emulation (as I do in my day job) using something like App-V to virtualise all of the calls an app makes into the OS and filesystem only produces a performance hit in the order of thousands of a %.

Sorry for Digressing the thread Boddrik, 3xS still gets my vote in the UK!
