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
- Edges and profiles are turned on.
