// The below is a bit hardcoded to try and match how scalability settings are set up in Scalability.h.
// This is because unfortunately scalability settings at their core are not very extensible or data-driven 
// and so it's difficult to do this in a data driven way. So I've made enums here to make the setup user friendly here,
// and then do the mapping in code. If scalability gets re-architected, this will need be to be updated to match.
