Continuing our set of movies, below is a video showing automatic database load-balancing.
Furthermore, this is a fairly new feature, just checked in yesterday. To my knowledge, Equalizer is the only toolkit on the market doing this (unless you count MPK ;) ). The only thing required from the application is the capability to use a different database-range each frame for rendering, the rest is done by Equalizer behind the scenes.
All this stuff is available in the brand-new 0.5.4 developer release.
