What? Your numbers are right, if you were running the game at 100FPS it would take 10ms to render a frame. Plus your 10ms of additional latency from holding the frame. 10ms + 10ms is 20ms.
If you were running the game natively at 50FPS, it would take 20ms to render a frame. That’s the same number. The total input lag from rendering is identical. Add in the slowdown from your GPU rendering the in-betweens and it’s even a little bit worse.
VSync may complicate this though, depending on the method, since you may already be holding a frame for some amount of time, I hadn’t considered that. I personally use VRR, so it isn’t much on my setup.










Yeah, that’s reasonable. I think it’s pretty cool tech, even if my own priorities and my display prevent me from using it as well.
The only place I really take issue with it is when someone like Capcom pushes it hard in a game like MH: Wilds to reach 60FPS. 30->60 is adding 33ms of input lag, in an action game, reaching a level of input lag we haven’t seen in the mainstream since N64 games that couldn’t push past 15-20FPS.
Once you’re at least at 60FPS native, you’re only adding 16ms of input lag, and that begins to feel like a pretty reasonable trade if you really like that smooth look.
