|Is that the new physics engine over there?|
Turbine has been working on the main physics engine that powers our beloved DDO. Not sure what they are trying to get accomplished (lag reduction?) but some of that code has to be eight or nine years old by now.
I can tell you from personal experience that eight-year-old code will have been patched and tweaked so often that it becomes very difficult to apply new fixes. It may be easier to simply rewrite large chunks of the code. Meaning Turbine may not be adding anything new at all but simply trying to keep the place neat and tidy.
But I digress.
