Hi! I have been asked for help for a mix of two shaders with a pixelated effect, and I saw a great oprotunity to apply all my studies about volumetric lights. Given its low resolution and its foggy taste I thought it should work and it works!
My NvidiaGTX285 spends less than 1 millisecond to render 5 lights and no more, but more than 6 ms an AMD card
