I have spent some time applying some further tweaks of my own to "crt-lottes-tweaked" which, in my opinion, duplicate the look and feel of "crt-lottes-fast.subtle+gain".
I did this because, as much as I like the latter shader, I was never satisfied with the lack of easy configurability in relation to bloom, brightness boost and curvature settings.
I believe I have come up with something that effectively duplicates dosmax's high quality 90's CRT look, but with a brighter effect overall, which I think looks a bit more like a real CRT.
Anyway, I will provide them here.
The first is the regular version, which I think looks good across the board, but preserves decent contrast for small/black text in higher resolution SVGA DOS and Windows titles.
The second version is one where I maximized the bloom and brightness boost (while preserving the visibility of the shadow mask on pure white) which I think looks better on CGA/EGA/VGA DOS titles, to give them more of a CRT 'glow'. The downside is that in SVGA modes, black text can tend to look washed out and too blurry.
I have turned off the curvature on these, but it can be easily configured to taste.
I hope someone other than me finds them useful. The only proviso is that I did all my testing on a 5k screen, so I cannot vouch for how it may look in lower resolution.
