Lots of RAM is no good if your RAM preview disappears each time you make an edit fast storage doesn’t mean spacebar play of a time-line in real-time and until CS6, the high-end graphics card that you purchased to work in Maya or CINEMA 4D hardly made a dent in After Effects interactivity.Įach of these areas of performance is directly addressed in After Effects CS6.
In the past, After Effects has rather notoriously failed to take advantage of these advantages.
high-end graphics cards with GPUs that accelerate performance year after year at rates that way, way outstrip Moore’s Law. fast attached storage, including SSD drives that routinely double the access speed of even the fastest HDD drive or array. cheap and plentiful RAM, and the ability of a 64-bit operating system to access far more of it (up to 192 GB on Windows 7, and well in excess of the 2 GB per processor core recommended for After Effects). Global Performance Cache is the result of looking at what modern hardware can deliver that simply was not possible a few years ago, and figuring out how to make use of that hardware: Engineers too easily assume they need to tear technology apart and rebuild it from scratch in order to modernize it. You have to hand it to the After Effects development team here. an updated graphics pipeline that makes greater use of OpenGL to present and stream images onscreen, including the UI overlays that are a constant when working in After Effects. a persistent disk cache that saves those precalculated processes for continual reuse. a Global RAM cache that is smarter about dividing your work to save as many individual processes as possible. The feature name “Global Performance Cache” is a generic term for what is, in fact, a set of interrelated technologies: You don’t technically need a book to experience what can be extraordinary benefits from how After Effects CS6 preserves your work in progress for instant playback you probably already know and love this feature, but as a reader of a book like this you probably also want to know as much as you can about how it works so you can maximize what it does for you. We’re over 100 pages into the book and just now getting into the most revolutionary addition to the latest version of After Effects. Sometimes it works, but it’s not really supposed to work, and most often it doesn’t. 
Although After Effects doesn’t prohibit you from doing so, don’t apply a track matte to another track matte and expect consistent results.
