Intrepid modder builds Frame Warp demo from Nvidia Reflex 2 binaries — tech remains mysteriously shelved despite greatly reducing latency

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.

Weirdly, though, Reflex 2 with Frame Warp hasn’t been pushed into broad release even as we near a year after its announcement. All GeForce RTX 50-series cards describe it as “coming soon” in their spec tables, and there hasn’t been a peep about the tech being enabled for its headlining integrations at CES: The Finals and Valorant.

The modder PureDark, who works in part on putting upscaling and framegen technologies into games that lack native implementations, recently found that the ARC Raiders Playtest files included DLL files that appeared to be related to Reflex 2’s Frame Warp functions. With these files in hand, PureDark created a basic working demo of Frame Warp that you can download from Patreon.
