CAS is a sharpening filter, not a CRT effect shader. Anything run through it will look less like it would on a CRT screen. If you find it's making things look nicer (which it often does), then you probably don't want a CRT effect.

i dont know if should call it crt

but if you install aethersx2 1.5 version

theres option enable this cas sharpness from 0-100

i set it to 3

at 1x res on 10 inch tablet like tab s4 etc....
it feels like 100% correct output from old tv
