It works just fine in a number of those games, so no you aren't better off at all. Most people have't gone through a full forum indoctrination where they are taught to hate it despite having never used it, they turn it on, see everything gets significantly smoother and are quite happy.
I haven't been indoctrinated into anything. I read reviews and looked into how it works and made up my own mind.
Frame Smoothing (what it should really be called) has it's uses, but they are in a limited range, mostly in titles that are
CPU limited, or games where reaction time doesn't matter. The poster child for this is MS Flight Simulator, because it's both CPU limited, and not a game were reaction time matters at all.
In games (like shooters) where reaction time matters, turning on Frame Smoothing makes things worse since it increases latency, so you are much better off having the card that delivers a higher real FPS, or turning down some settings or using scaling (FSR/DLSS 2) to increase real FPS.
I'm not against Frame Smoothing, just against misleading marketing that portrays it as equivalent to the real frame rate, which it clearly isn't.
