I’ll have to answer you in parts with a few edits.
To raise the brightness, I suggest either increasing the Post CRT Brightness Setting which is near the top of the Shader Parameters List or changing the Scanline Type – gsl to a lower number. You shouldn’t need to touch anything else to get a great look that’s brighter.
Most of what you’ve read on Reddit over the past few months is probably already outdated.
The RGB Sharp currently in my Shader Preset Pack currently represents the “Old” look. It’s all a matter of personal preference any of them can be customized to get the type of look or to cater for different scenarios. I can’t recall saying that any particular one of my presets is the best. I might have had my favourites or ones that I used the most at the time.
It’s easy to get a curved “Screen” without curving the game. HSM Mega Bezel Reflection Shader supports independent curvature.
It’s just a few settings to adjust and I’d be happy to assist you in that regard. You can try to look for those options in the meantime and just save a Game or Core Preset when you have what you like.
The difference between Blending and Transparency and Composite - Sharp is that MDAPT is set to Mode 3, that’s all. It’s used for games like Sonic but can really mess up graphics and text in some games. So you have to see which games work best with which settings. Some look best with MDAPT off. Some look better with ScaleFX Off.
Composite - Pure is Composite - Sharp with both MDAPT and Scale FX disabled.
I have to run off now but feel free to follow up and explore the settings I’ve mentioned. I’m glad you like my presets! It feels good to know that I can share something that makes me excited and brings me joy with others. Be sure to share this with others that they too will also enjoy.
