visiting the "decoder" page I read the following under changes in beta 2:

More routines have been implemented in SSE for acceleration on older processors


Its good to see someone who is interested in optimizing their code instead of relying solely on hardware acceleration. 

given the difference in CPU use when h/w acceleration is enabled in some of the existing codecs you've got to wonder how much effort goes into optimization these days

Note that x264 and ffmpeg based encoders have a lot of CPU specific optimisations, there is also constant work to improve multi-threading.

The encoding/decoding world is most definitely not standing still.
