why is bootcamp supposed to be slow? hardware-wise macs just are normal intel pcs now and i thought that bootcamp isn't an emulator or virtualization solution but just helps booting windows?

I planned to make my first Unity game : An hovercraft race

A Unity member asked how to change the friction factor in the run time

As you realize it would be quite inportant also for me since an hovercraft can move over any type of terrain

Well apparentely in Unity it is not possible

3DGS supplies new commands in any new releases
you mean different physics engine friction values for certain level geometry or terrain parts? i am not sure about unity but gamestudio's physics engine doesn't support this either and it's buggy, outdated and didn't have an update in years. newton does support it though.
