It just kinda makes no sense to me. How can you improve the framerate by predicting how the next frame should be rendered while reducing the overhead and not increasing it more than what it already takes to render the scene normally? Like even the simplistic concept of it sounds like pure magic. And yet… It’s real.
It absolutely does increase latency though. If I’ve got the option for steady frame rates without frame gen, I’ll take it over frame gen. Frame gen was just about mandatory for Borderlands 4 at launch, and it gave me a convincing 80 FPS. After a performance patch, the game can get 60 FPS on my machine for real with a few of the settings knocked down, and it feels so much better.
