Using time display script in MoI....

1000 Spheres in Array (cube arrangement), mesh=5 deg.

2000 ms in prior version.
1069 ms in new version.

2x increase.

So it's good for larger shear quantity of surfaces. - when its more about large amounts of poly data being processed.

Not as much noticeable with simpler models. - when it's more an issue of the bottleneck with the PC communicating with the vid card.
In one case, when I was using a smaller number of objects. I noticed that the newer version was slower than the older.
