Lag is the eternal arch enemy of every sketchyphysics user. It comes from many things, but they all end up the same way: Choppy animation, incorrect physics, and sometimes a Bugsplat. In general, the more stuff you have in the model, the more lag. It is also important to know that lag has little to do with file size. A 10 megabyte file can be relatively unlaggy, while a one megabyte one can give people bugsplats.

In general, lag is caused by:

  • Complex textures
  • Objects stacked on top
  • Shadows
  • Edges and profiles are turned on.
