根據官方說法，效能應該變得很屌，主要幾個 Key New Features列在下方：
3D Effects - Easily transform and animate any display object through 3D space while retaining full interactivity. Fast, lightweight, and native 3D effects make motion that was previously reserved for expert users available to everyone. Complex effects are simple with APIs that extend what you already know.
Custom Filters and Effects - Create and share your own portable filters, blend modes, and fills using Adobe Pixel Bender™, the same technology used for many After Effects CS3 filters. Shaders in Flash Player are about 1KB and can be scripted and animated at runtime.
Advanced Text Layout - A new, highly flexible text layout engine, co-existing with TextField, enables innovation in creating new text controls by providing low-level access to text offering right-to-left and vertical text layout, plus support for typographic elements like ligatures.
Enhanced Drawing API - Runtime drawing is easier and more powerful with re-styleable properties, 3D APIs, and a new way of drawing sophisticated shapes without having to code them line by line.
Visual Performance Improvements – Applications and videos will run smoother and faster with expanded use of hardware acceleration. By moving several visual processing tasks to the video card, the CPU is free to do more.

（此 Demo 展示的 3D 和 Filter 特效順得很，看來面對 SilverLight 和 Processing 的衝擊，Adobe已經準備好反擊）
