From my understand after reading, he's suggesting that Unreal and Unity's post processing are just applying effects to a camera/rendered frame, when what he wanted to do is simulate the CRT itself across the renderer to the frame that hits the swapchain.

But that's nonsensical. The CRT doesn't see the graphics pipeline of, say, an SNES, it just sees an analog signal. The graphics processing is done in the digital realm, not in the analog realm. If you want to simulate a CRT, all you need is a physical model and a digital image to display, which can come from Unreal, Unity, or whatever any other engine or program or whatever. It makes literally zero sense to write an entire engine to implement a CRT simulation.

I didn't suggest it makes any sense, just explaining, based on my understanding of the article, why he analogized the game engines to renderers to cameras.
