* - Disable collisions for objects that don't need it. (Personally I think this should be disabled by default)
Great list. However I think disabling collisions by default should be a setting for the editor for those who prefer it.
As I said before, I say it again. It's always a good idea to try out other engines and see how they fit your needs. Just keep in mind that there are other aspects for creating a game than just pure performance. If you chose a native engine and get +4 FPS while you game takes +6 months to create, does it worth it?
