That doesn’t have anything to do with DLSS or FSR, that’s just because the frame time itself gets shorter. That’s why 120fps games have lower input latency than 60fps. However, DLSS 3.0 frame gen does have have a bespoke anti-lag solution called Nvidia Reflex, which basically reduces the rendering queue on the CPU side (along with some other input tricks), but I believe that has to be implemented by the developer using Nvidia’s SDK. I don’t know that much about it though.
