Currently I'm widely using Irrlicht (C++) and GLScene (Pascal). Both are opensource. I studied their internals. There's no such entity as "distance units" there.
At least in vector geometry and basic primitives (including meshes) areas. If you had a chance working with any, can you provide a code reference with "distance units" ?
Moreover

According to Newton Laws (and I belive to NGD too) any object is falling (we' re about classic free falling bodies with just only gravity taken in account) with the same aceleration.
It means any two objects (absolutely no matter of size, units and even mass) are falling with the same speed at the same moment. So it cannot be slower by the reason of "wrong size".
Again, please check for yourself.
Sorry, this discussion becomes an useless offtopic. According to my experience and public source code I just wanted to help Mag-got, by pointing him the problem is elswhere but not in "Irrlich numbers".
If you belive I'm wrong, please prove your words by facts. Otherwise please stop misinform people. No offence.
