Hello, am curious about this engine

Am thinking about buying license and some packages, but wanted to check and see what the "state" of things is with the engine. I wasn't particularly impressed back in 2010, but really am reconsidering given how wonderful and well-made the suite is.


ie. How well does the Physics system work on xbox platform? (with regards to lag tolerance)
and is it a wise investment as opposed to something such as http://www.visual3d.net/ , or rolling your own with Ogre (Axiom for the XNA & C# support)?
I get the feeling that visual3d is still quite an infant, but I wonder how it compares performance wise.
When your target is both people with new _and_ old computers, performance is key! :)


Any feedback is really appreciated.
