Yeah, scaling in interlaced mode seems to be off and some other issues. I guess it’s not a top priority for Toni to fix it before the new official version is out, but will probably mention it later in my shader thread.
If i go trough the naming scheme a bit, SmartRes shaders work with every internal resolution combo, but only the HiRes versions keep horizontal details. Interlaced shaders don’t skip lines and preserve vertical details. But it’s recommended with new WinUAE (beta) versions to use different shaders for standard and laced content.
You can use the A2080 for normal mode and there is a bunch of viable options for the laced mode, but you can try the
CRT-Guest-SM-Hires-SmartRes-Interlace-no_scanline.fx as something standard to use.
