If you are fine with a tool that you need to tune to your personal likings for every game that would benefit from it and someone is willing to code it, then yes, it’s totally ok!
But If you are still hoping for something that would automagically guess the right settings, then it’s a totally different story, and I’d go back to find the road to drive my F1 car, prior to buying it.
Please let me refer you to reply number 28. And the article linked within. The goals (or circuits in your F1 analogy) have been stated and explained very clearly already, there’s no need to do it again.
I did play with it a bit
with adaptive black 0.02 and brightness -0.02 (OFC with co=1)
yes, this seems how the game devs/artiest want us to see (they put that crt “crushed blacks” in their mind when they made old games)I really want to use that in my preset, but koko-aio seems has tons of things I don’t need or that are duplicated in the guest shader, also koko-aio is kinda slow to load in the first time
it will be nice if that “feature” become a standalone shader
and since you got “crt breathing” in koko-aio (which I didnt know about and I thought the only one that did it was guest [as raster-bloom]), so the best will be if you make all-in-one shader for flyback adaptive voltage (or whatever) that do effects 03-05 from Crt effects list
