According to VMware, Fusion 3.1 is faster in application, interface and graphics performance, supports Windows 7 Aero and Flip 3D, and increases its virtual hard disk size from 950GB to 2TB.
Overall performance for applications is 35 percent, according to a Wednesday post on the Team Fusion blog.
On the graphics front, the update delivers 5x the 3D performance than the previous version. Windows Aero performance was also improved for Windows 7 and Vista, the company said. The improvements have caused Autodesk to support Version 3.1 for AutoCAD 2011.
Unity is faster than ever from dragging and resizing windows to interacting with Windows apps. VMware Fusion 3.1 adds support for overlapping windows in Exposé and minimizing apps to the Dock. Only VMware Fusion supports Mac OS X Snow Leopard’s Dock Exposé for individual Windows applications so Windows apps work even more like Mac apps in Unity.
The update is free to Fusion 3.0 customers. Here's the Fusion 3.1 Change History document on the VMware Communities site.
