The option served absolutely no purpose (sorry, working around the osx lighting issue doesn't count). However, lots of noobs where coming to our forums complaining about issues with lighting when "Disable lighting" was used (ofc they didn't notice they enabled that option because they just blindly took over the settings from mamario's idiotic performance guide).
So it's basically no advantages vs that pretty annoying "disadvantage" (if you can call it like that).
