One thing I haven't seen CRT shaders really replicate is the brain-melting flicker that comes with that technology. LCD was such a relief when it became common.

People have varying sensitivies to flicker, but the refresh rate of even basic cheap CRT monitors was something like 75 or 85 Hz, which most people found essentially flickerless. Higher-end monitors would go up to 100 or 120 Hz, one of the several ways that for some use cases they were superior to LCD displays for quite a long time. Televisions, at 50 or 60 Hz, were pretty bad of course.

This CRT shader actually has a flicker slider. But 'brain melting flicker' sounds more like you were gaming with a 50Hz PAL console (or home computer) on a professional computer monitor which was intended for higher frequencies (like 72Hz). Regular TVs normally had plenty of 'afterglow' to reduce flicker.

Of course that is also available as a shader: https://news.ycombinator.com/item?id=42506211

Have you tried BFI (black frame insertion)? Many people swear by it because it improves the "motion clarity", but it has the side effect of significantly increasing flicker.

They also don't replicate the 15khz whine that makes CRTs incredibly annoying for me to use
