The picture quality looks amazing, but does the filtering create any video delay (aka. input lag)?
From what I've read so far, there seems to be a minimal input lag. It also depends on the source signal and TV.
I quickly ran the manual input lag test from the
240p Test Suite on the Sega Mega Drive. I didn't recognize a difference between my Sony LCD and Philips CRT. But I'm really not a reference nor an expert. I wouldn't recognize an input lag of 1-2 frames.
But the Framemeister LCD picture is so much better compared to the CRT, that I will probably use my CRT only for some SAT and DC lightgun games in the future.
