Do you have an example? I’ve done a slightly-more-than-casual search for convincing post-processing and haven’t found success. Filters still tend to retain the sharpness of pixel edges in a way that CRTs don’t, and the contrast doesn’t look right either.

I'm not saying the tech currently exists in a form you can just plop into a project and have it give you the exact CRT look and feel that you want. What I am saying is that you can do that within any modern game engine - you just have to decide what, exactly, the look and feel you want is and how to get there.

As an example, I will quote the article:

> Retro Game Engine owns the full frame lifecycle. I decide what the input signals are, what the display does with it, how time affects it, what gets presented and when.

You can replace "Retro Game Engine" in that sentence with "Unity" or "Godot" and it is just as true.

Balatro is a good example. Lots of different opinions on whether its a good CRT effect or not.

Still the best CRT simulation I've seen is in an X screensaver called XAnalogTV. It simulates both CRT artifacts as well as NTSC channel cross-talk and analog interference. It amazes me that still no one has produced a portable version.

I think you are underestimating what a filter is allowed to do.

You could build a simulation of the universe, send the frame data to the CRT inside that universe and capture the output of the simulated CRT and show it on the LCD.
