I want to see this on 30fps games delivering 60fps.

FG has an inherent one frame worth of latency, which is 16ms at 60FPS and 33ms at 30FPS. At 30FPS you'll end up with a 66ms frame related latency vs 33ms at 60FPS (on top of engine latency, input latency, display latency etc.) and that's gonna be quite unpleasant.

Even 16ms sounds extremely unpleasant, how is this even something people wanna use?

FG at 60FPS has the same theoretical latency as 30FPS native. Most people game at well over 100 ms (click to photon), so if you have a low latency display, a good gaming mouse, etc. an 16ms is really not bad at 60FPS in non-competitive games.

Also games that use FG can potentially implement latency reduction tech. For instance, Nvidia DLSS 3 titles sometimes end up with lower than native latency thanks to Nvidia Reflex.

But FG will never gonna be good at 30fps. At 45FPS, it can be fine at best case scenarios.
