Nvidia's Reflex 2 latency reduction tech, introduced alongside its Blackwell architecture, was meant to introduce spatial reprojection - aka "Frame Warp" - to fast-paced games in order to lessen perceived input lag. It also has promise alongside Blackwell's Multi Frame Generation when it's enabled. MFG comes with a substantial input latency penalty when it's running, and Frame Warp could help mitigate it.
As a very quick refresher, Reflex 2 with Frame Warp uses fresh mouse input data collected while a frame is rendering to predict and reproject the camera position of that frame in progress right before it's sent to the display, a process Nvidia claims will heighten the sense of "connectedness" and responsiveness delivered by the PC.
