Very nice! Any issues with the rendering speed of complex graphs or
scene/object movements?

Well, everything for Ogre itself, but you do have to install a fair
amount of stuff before installing Ogre from what I gathered...

I wouldn't say that. Ruby speeds are expected to improve, but it will
never be C or C++ speed.
I do predict some game dev tool makers to officially begin
implementing Ruby as a scripting language for their engines within a
year or two!! (the sooner the better, imagine the expressiveness!)
