I was a bit disappointed on the fact that shaders on 1080p are subpar, so I decided to use integer scaling, just that I will scaling up to the next integer (not the previous). I checked for the 8-16-bit systems and mostly this is fine, it makes the game bigger on the screen and the hidden portion is frequently supposed to be hidden on a CRT. But after checking a few images with integer ON and OFF I spotted some strange bands on the Integer screenshot so I would like to ask you why I am getting worse scanlines at x5 than at x4.5, check on the sky area at the right.
I’m using crt royale-320-svideo.glslp with a D93 temperature.
I also wanted to ask on shaders for the Naomi or Dreamcast system. Supposedly this board was outputting 640x480? If that’s the case 2D games never presented scanlines in this system? The next is Metal Slug 6 (Atomiswave), while the shader (the same than the above) looks superb on 3D games, I wonder how 2D games looked on real arcade cabinets.
