OpenSceneGraph on steroids. This fork was created to experiment with
performance enhancements for OpenMW that are too controversial to be
included in the general purpose OSG project - either for design reasons
or backward compatibility reasons. OpenMW still works with "vanilla"
OpenSceneGraph, but it is recommended to use the fork for better
performance (around 10-15% on most devices). Note that the improvements
are very specific to OpenMW and its animation code in particular; other
OpenSceneGraph applications are not likely to see the same speed-up, or
any speed-up at all if they are already GPU limited.
