NVIDIA recently gave a demonstration of an upcoming version of Adobe's Flash player that takes advantage of GPGPU computing to accelerate 720p HD video playback.
The (fittingly high-definition) video shows laptops with Nvidia Ion integrated graphics attempting to run a 720p Star Trek trailer, also on YouTube. The first system's attempt is unwatchable, but the second can pull off completely smooth playback. It has no trouble with the trailer for the new Harry Potter movie, either.
What's the difference? Apparently, the second laptop uses a new version of Flash that taps the GPU for rendering.
