I am doing a research on deferred rendering since I will probably want that type of rendering in my game. Now I think I know how is it supposed to be done but most articles and tutorials that I red were either deferred lighting or deferred shadowing it was never both at the same time. Why is this? I think it was Epic's Samaritan demo that said it uses fully deferred rendering. Which deferred rendering is actually better between the two? Is there a benefit in using both at the same time (deferred lighting and shadowing)?
