I just don’t get it - let’s spend so much money, development and hardware to render the most clean game possible, avoid aliasing and increase detail… And then let’s enable color distortion as if we were vieweing the game through a 1930’s cinema projector. Add in some film grain too! This saves me the effort of covering my monitor with dirt!
Make sure to make those options enabled by default on every game you release too!
I always turn it off. In photography CA is a bad thing. All lenses have it but a poor lens design will have more if it. It’s a thing that everyone wants to elimate to have a good photograph.
What’s fascinating is that lenses for photolithography, the process used for projecting the patterns of the mask on the silicon substrate in the manufacturing of integrated circuits, have almost no aberrations, or at least their effect is negligible! That’s due to the awesome engineering behind modern lens manufacturing. These were brought about, for the most part, by growing automation and computerisation and subsequent gains in precision. This means that imperfect lenses were once used for photolithography to make ICs, those ICs were then used to make better lenses, the resulting better lenses could make better ICs again, etc. We owe so much to computers!
That’s a big problem if all was lost and we had to rebuild just from experience. You can’t just make a 5nm chip because you know how to do it. You need 7nm chips in the machine that makes 5nm chips. That machine needs 12nm chips, and so on.
