Are they 32bit cpus or 32bit windows? I recall windows inexplicably treated(treats?) 32bit and 64bit as being separate purchases for some reason (I assume money, given they limit supported core count according to which type of windows you buy).

But more seriously: why ship 32-bit only software. 64bit has been supported by all cpus intel and amd have shipped for more than a decade now. I had a consumer 64bit Athlon in 2005/6 that I could afford on a student budget. Given the perpetually increasing cpu demands of modern games, that you'd throw away something in the order of 15-20% perf by not support 64bit just seems insane.

Seriously: make 64bit your primary target, and if that hurts 32bit perf, that's those user's problem: they chose not to buy a high perf system.

32-bit Windows. Most of them are probably running on a 64-bit capable CPU, but one that can't be used without replacing the OS.

If only MS never charged more for the 64bit versions :-/
