Conclusions
This Flash 10.1 beta is just a first step, and obviously both Adobe and the various GPU makers have some work to do yet. GPU acceleration is still pretty fragile, and although AMD and Nvidia seem to have a good handle on the basics, Intel's GMA 4500MHD currently doesn't perform very well. Even so, most of the initial performance indications are positive. One can't help but be encouraged by watching an Atom/Ion-based system playing back Flash video with fluidity.

Heck, I'm not even sure exactly how to feel about this development. For so long, Adobe and Flash have been objects of derision for many PC enthusiasts, because really, how could Flash not be GPU-accelerated? Now that it's happening, I suppose I feel more relief than gratitude, like a captive being released from a terrible ordeal—only, you know, in a really muted and low-stakes way.

With that said, unless things change, GPU acceleration of Flash video won't extend to some notable platforms, including the vast majority of today's netbooks and nettops. Not only does the 945G chipset not support H.264 decode acceleration, but as of now, Intel only has 4-series chipset video drivers supporting Flash 10.1 for Vista and Win7. A great many older systems, both Atom-based and Windows XP-based, are likely to be out of luck. That fact ought to put the damper on some netbook buying decisions this holiday season. Then again, I wouldn't recommend buying any netbook when dual-core CULV systems like the excellent Aspire AS1410 are selling for just over 400 bucks. I'll have to admit, though, that I am curious about the Flash video performance of a single-core Atom/Ion netbook. If we get our hands on one soon, we'll be sure to test it.

The very best news here is that GPU video acceleration is just a first step on Adobe's roadmap, which includes plans for GPU acceleration of all sorts of Flash animation going forward. Full-on GPU acceleration of the Flash platform could lead to dramatic improvements in battery life and the perceived user experience for low-cost, low-power systems. So, to all involved, I'll say: keep doing what you're doing. The sooner the better from our standpoint. Please, think of the kittens and babies.
