Adobe wird demnächst Photoshop CS4 veröffentlichen. Neben den üblichen über-drüber Verbesserungen, sticht eine Eigenschaft heraus: es wird erstmals eine 64 Bit Edition geben. Allerdings vorerst Vista only, laut Zeitplan wird erst für CS5 auch Mac beglückt.
Aus der FAQ:
Does Photoshop CS4 Extended support native 64-bit processing?
Photoshop CS4 Extended for Microsoft® Windows Vista® runs 64-bit native.
What are the advantages of 64-bit computing?
In early testing of 64-bit support in Photoshop Extended for Windows®, overall performance gains ranged from 8% to 12%. Those who work with extremely large files may realize noticeably greater gains in performance, in some cases as dramatic as ten times the previous speed. This is because 64-bit applications can address larger amounts of memory and thus result in less file swapping — one of the biggest factors that can affect data processing speed.
Why is Photoshop CS4 Extended 64-bit native on Windows only? What about Mac OS?
The Mac OS 64-bit version is planned for a future release as a result of a change to Apple’s platform strategy, which now requires a migration from Apple’s Carbon technology to its Cocoa technology in order for an application to run 64-bit native. Before 64-bit support can be added on Mac OS, significant parts of Photoshop Extended and its plug-ins must first be ported from Carbon to Cocoa. The Photoshop team began working on porting Photoshop Extended to Cocoa as soon as Apple announced 64-bit support in Carbon was no longer part of its plans.
