Flat-screen TVs are the worst thing to ever happen to gaming. I used to be an expert at Guitar Hero, Rock Band, and other music/rhythm games. At NordicFuzzCon '19, when there was a system connected to an actual CRT, it was like nirvana. Not anymore. It's all laggy bullshit.
Thanks, but earlier in the thread I specifically noted that I have my TV set to "game mode", and even then I'm still looking at what feels like roughly 50ms of video lag and 15ms of audio lag. Game Mode isn't a magic bullet by any means.
