Thanks! Yes, it adds some latency: RGB2RTG builds each frame completely and then shows it on HDMI locked to the Amiga's 50 Hz, so the picture appears about 25–30 ms (roughly 1.4fps) after the Amiga draws it, plus your TV's/Monitor own processing (input lag). A line-by-line flicker fixer like an Indivision adds less (Its HW). For the eye candy: scanlines (several levels) and smooth scaling are both built in, alongside integer scaling and aspect options.
