Cube vs. NXS

Hm, this might have been asked before, but I couldn't find any...
Question; if I have a cube, is there a difference in performance whether I declare it is a NxOgre::Cube or NxOgre::Convex? (The convex shape only has 8 vertices and loading time not a factor) If so, approximately, how "big" is it?
I guess it is, though... :)

Yes; a cube would have a bigger performance and use less memory than a convex. Assuming both shapes are the "same" physically.

Estimated, for an application which only spawns cubes, how many cubes would be required to make a noticeable change in performance on a regular machine today? (Just curious, as usually)

I can get around 200-300 cubes with some noticable dropping in frame rate; however I have a slower computer by today standards. NxOgre/PhysX have gone up to 10,000 but I would say 200-300 is about right.

Okay! Once again, thanks!
