Reply To: Scanlines overlays and configs for a softer look

[dankcushions]

an overlay image is only for a specific native resolution. you can get a full screen 720/1080p scanline overlay but because each core would usually have a different native resolution (that is scaled up to 720/1080p), the lines will be in the wrong place.

retroarch shaders ‘know’ the core’s native resolution so scanline shaders should always line up. however, sometimes at the cost of performance. check out @davej’s shader – https://www.petrockblock.com/forums/topic/new-crt-pi-shader-version/
