Reflex 2 was apparently already bundled with The Finals last year, but it wasn't active. A modder just took the DLL file and made a Tech Demo that lets users turn on the feature even on old GPUs.
Modder Builds NVIDIA Reflex 2 Tech Demo That Reportedly Works on RTX 20 and RTX 30 Series GPUs; Frame Warp Works Flawlessly at 100+ FPS FPS Cap
NVIDIA's Reflex 2 hasn't gained much popularity since the technology is hardly available except for a couple of titles. Despite having launched in January this year, most developers haven't integrated Reflex 2 in their games, particularly because it's mostly beneficial in competitive, fast-paced eSports titles. We do have it in some Triple-A titles like Dying Light: The Beast, but Reflex 2 makes more sense in games like Valorant and The Finals.
Surprisingly, the Reflex 2 was already bundled with The Finals last year (around May 2024) as per the modder "Pure Dark", who showcased how one can turn on the technology in supported games with his uploaded Reflex 2 Tech Demo file. He says that he "reverse-engineered" the nvngx_ratewarp.dll file that was leaked during ARC Raider's public test. After extracting and re-implementing this DLSS to make a small tech demo, Reflex 2 can now "unofficially" work even with older RTX GPUs.
NVIDIA has stated that the Reflex 2 technology officially works only on the GeForce RTX 50 series, but as per Modder's report, the tech demo works even on the GeForce RTX 20 series GPUs. DSO Gaming confirms that the tech demo also works on RTX 30 series, which means the tech demo should naturally work on the RTX 40 series as well. The Reflex 2 essentially brings what NVIDIA calls "Frame Warp" in order to reduce the latency for improving the gaming experience in fast-paced games.
Frame Warp ensures that the frame generated by the GPU is adjusted using the latest input, reducing the gap between "moving the mouse" and the final image. In simple words, when the GPU finishes rendering a frame, before it gets displayed on the screen, Reflex 2's Frame Warp asks the CPU to know the latest camera or mouse position and warps the finished image to align with the latest input.
As per DSO Gaming, this feature works great when your system is delivering 100+ FPS, but if you are getting 30-60 frame rates, you will see visual artifacts since the movement between the two frames can be quite large to warp properly. We don't know if there is any difference between the visual stability when running Reflex 2 on RTX 50 GPUs vs older RTX GPUs, but it's still great to see it running on previous-gen cards. However, we don't know if NVIDIA has any plans to release it officially for pre-RTX 50 series GPUs.
