Recently, the mod author PureDark released an unofficial NVIDIA Reflex 2 technology demonstration program, which uses reverse engineering to parse leaked dynamic link library files so that all RTX graphics cards can run.

Reflex 2 is a technology developed by Nvidia designed to reduce latency in computer gaming systems.It can shorten the time difference between when the player clicks the mouse or presses the keyboard and when the corresponding action is displayed on the screen, which is especially suitable for fast-paced shooting and competitive games.Reflex 2 only supported GeForce RTX 50 series graphics cards at the initial stage of its release, but tests by the mod author and foreign media DSOGaming confirmed that this technology demonstration can work normally on GeForce RTX 20 series, 30 series and 40 series graphics cards.

PureDark has released an unofficial Reflex 2 tech demo showing how to activate the feature in supported games.Through reverse engineering, he analyzed the nvngx_ratewarp.dll file previously leaked in the public test of "ARC Raider" and re-implemented this technology.This breakthrough gives almost all RTX graphics card users the opportunity to experience the core innovation of Reflex 2 - "Frame Warp".

Simply put, when the GPU completes rendering a frame of picture, this function will obtain the latest mouse or lens position from the CPU before the picture is displayed on the screen, and use this as a basis to "distort" the rendered picture to keep it synchronized with the player's latest input and shorten the time difference between "moving the mouse" and "screen response".

However, this function has certain limitations: it works extremely well when running at high frame rates above 100FPS, but at low frame rates of 30-60FPS, due to excessive dynamic changes between two frames, it may cause obvious visual artifacts.
