Photoshop CS6 has added loads of performance enhancements, primarily with the implementation of the new Adobe Mercury Graphics Engine. While there is some nice optimised and new 3D handling, quantitative analysis, and video manipulation options, Adobe has built the lot using 64-bit.
However, Adobe is making Photoshop CS6 availabe in 32-bit versions for Windows XP machines, though some features will be limited, but it is telling those who are running the software on 32-bit Macs to forget it.
This means that people in the content industry trying to work on older Macs have got a case to force their tight fisted employers to actually upgrade. The same might be said for those who are running 32-bit code on Windows XP. Adobe is splitting the Windows system requirements by dropping official support for Windows Vista.
To be fair to Adobe, it is not a slap in the face with a wet fish for Apple customers. Apple itself has pulled support of its 32-bit code either in hardware or software. The only reason it is still supporting Windows XP is that there is a large Photoshop user base.
However, Adobe appears to want the adoption and support of the latest OS X 10.7 and Windows 7 operating systems.
Adobe’s system requirements still claim it requires a DVD drive, which Apple has been slowly migrating away from.
