What are the advantages of 64-bit computing?
In early testing of 64-bit support in Photoshop 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.
