+		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.
