>>I want to do photorealistic looking games in first place using PoM+DoF+GodRays+Realtime Material Reflections<<
..I hope you will make it..far as a know, everything you really see is color and color balance between objects and scene in general, and thats whats makes it real and thats what you really see in real world..putting your hopes in to postprocessing features while basic color scheme is ignored as well as texture artwork, is a big no no, in case of hunting for photorealism..so, here is my suggestion, rather than spending time on pumping your scene with VFX, try this:
1) Spend MORE time on to extraordinary good looking textures..thats major part from where comming your 'photorealism'
2) Spend MORE time on to proper GI and atmosphere lights
3) Spend minimum time with VFX you mentioned because you will see that they are just nice polishing things making your scene looking really nice, without much use of them(VFX)
if you miss 1) and 2) no VFX on this world will make your scene looks photorealistic..
