When someone tells you an Nvidia feature doubled their framerate, you probably immediately think of DLSS Multi Frame Generation or maybe the upscaler using the transformer model. Those features can be useful, but when it comes to fast-paced games where visual clarity and low latency are crucial, they're better left disabled. When I first heard of Nvidia's Smooth Motion toggle, I thought the same thing.
Another frame generation setting that would add a ton of latency and not much else, so I ignored it until someone mentioned trying it on one of my favorite games, and it honestly blew me away. It doubled my framerate with next to no visual artifacting, and it actually lowered end-to-end latency. It doesn't work flawlessly in every game, but in the games that it does, it's really effective.
