Some of the new features to be found with NG3D2.0 are dynamic volumetric shadows, enhanced lighting and modeling, high definition characters, enhanced post process effects, performance improvements upwards of 50%+ faster, and an increase in the drawing distance of scenery. Beyond just the game engine, there are also some improvements to the game-play as well. This update is being introduced as part of the two year anniversary of Regnum Online.
More information on this update can be found in the company's press release. This game is still no World of Warcraft or Everquest when it comes to the game-play or graphics, but at least there is native Linux support from NGD Studios.
