Multimedia, AV It's been a very long wait, but the release is finally here: Adobe has released Flash Player 10.1. Since Flash has come under increasing scrutiny, there's a lot at stake here for Adobe. This release is supposed to use far less resources while still being faster, more stable, and more secure. Update: No 64bit Flash player for now - on any platform. The Linux beta has been axed.

Misleading to the max. It's a 32bit Vista vs 64bit Vista....

Windows doesn't run in 64bit mode on x86 systems. Microsoft uses the 32/64bit mode; this means that the CPU is running in 32bit mode and only the address is done in 64bit. Thus, they don't get the extra registers; and the only speed up you're seeing is caused by having a larger address space.

This also explains why 32bit mode can be faster then 64bit mode. Since the everything except addresses are the same, the size of pointers are doubled meaning extra processing and storage space for them.

The only true 64bit version of Windows is the Itanium version. Microsoft didn't want to create a Win64 API for the x86 processors.

Linux, FreeBSD, & Mac OS X all run in true 64bit mode and can use the extended register set.

I don't know if Linux supports running 32bit & 64bit applications on the 64bit kernel.

Mac OS supports both 32bit on 64bit kernels and 64bit on 32bit kernels. For some reason, they just want programs to work.
