avoid scaling math calcs for faster framerate?
bypass the scaling math?

I am completely lost there... If that is true someone please explain this to me.

I thought changing the scale of static objects (like your buildings you are trying to scale) had 0 impact on framerate beyond the initial loading of the objects.

P.S.: I also dont understand the topic of the thread very well. The size of your objects only matters relative to the size of your other objects. I think there is no "correct" scale for your buildings other than the scale you want to choose.

P.P.S: Just to test I loaded a level I had previously created, but with everything 5 times larger... The result had zero impact to framerate.
