The 2D CitrusEngine is now GPU accelerated thanks to Starling (the Stage3D framework). Aymeric Lamboley, an engine contributor, announceted today that CitrusEngine has a new Starling view that enables the engine to use Stage3D capabilities.

It’s a pretty exciting news for all Flash game developers. Also I just noticed that CitrusEngine is now free and open-source since October 2011.
