ok, guys. this is actually very simple. there is no way you can fix aliasing in postprocess. and you perfectly know it. so, stop wasting your time inventing new hacky techniques and devoting more shading power to them. please do face the real challenge: use the silicon to implement massive supersampling (we can start with 8x, no need to go the standard 121x of the film industry), and make it transparent to the user. until you have that, stop bothering us. seriously. thanks a lot from the deepest of my heart!
also, remember that TV was 600 px wide and it always looked far more real than any 1920 videogame – it’s not about pixel shading power, it’s about geometry supersampling.
