 	<longdescription lang="en">
 		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.
