what is render, search wiki for it. too big to tell.
basically, it is creating a scene which is in adherance to the rules of physics.i.e. lightning, etc
renders can be done i real time, but xtreme power is required( which is what games are trying to achieve),
passive rendering creates immersive, real scenes, but u generally take a coffee
break while waiting for it to happen. (like rendering option in 3DMAX)
and jk, these graphics are no big deal, cricket is a game which can be low on resources, hence can have powerful graphics be achieved.
and the brightness of pic posted above is excellent.
