There are different techniques to make old games look better or more authentic on modern displays. Upscaling, filters, scanlines. Idea of the BFI is that CRTs didn’t output a frame, but a line of pixels, in a snake-like pattern. So every frame was completely erased before the next started. LCDs work in a different way: one static picture is replaced by another. Which suppossedly creates some kind of a blur.
The idea of BFI is that if we take 60 frames, and add a black frame after each image, we will reproduce the fidelity of a CRT on 120Hz monitors.
The problem is, it doesn’t work for me.
I started with RetroArch. You need to set monitor to 120Hz, even if it supports 144Hz, because the technique works only with whole numbers, otherwise you’ll get flicker. It works, but the picture is twice as dark, and I don’t see any improvement in motion clarity.
Then I tried RetroTink 4K on my Samsung QLED. This was a disaster, as the best I could get was a slightly flickering image with colors that are way off. Not as dark as on a monitor, but I also didn’t enjoy the results at all.
