Last year, NVIDIA’s Reflex 2 technology was already embedded within The Finals, albeit inactive. Recently, a modder managed to unlock this feature by utilizing the DLL file to create a tech demonstration that allows users to activate the benefits of Reflex 2 even on older GPU models.
Modder Creates NVIDIA Reflex 2 Tech Demo Compatible with RTX 20 and RTX 30 Series GPUs; Achieves Frame Warp at 100+ FPS
Despite its technological prowess, NVIDIA’s Reflex 2 has not achieved widespread adoption since its introduction in January 2023. Most game developers have yet to implement it in their titles, primarily because the technology is most beneficial in competitive eSports environments. While it does appear in a few AAA titles like Dying Light: The Beast, its functionality is particularly advantageous for fast-paced games like Valorant and The Finals.
According to the modder known as “Pure Dark, ”Reflex 2’s potential was documented last year when it was found ready within The Finals in May 2024, although it hadn’t been activated. Pure Dark revealed his process of reverse-engineering the nvngx_ratewarp.dll file, which surfaced during the ARC Raider’s public testing phase. By extracting and modifying components of this DLL, he has enabled Reflex 2 to function “unofficially” on older RTX graphics cards.
NVIDIA has clarified that the official support for Reflex 2 is exclusive to the GeForce RTX 50 series. However, reports indicate that the tech demonstration operates effectively on RTX 20 and RTX 30 series GPUs as well. According to DSO Gaming, there is a high likelihood it will also work on the RTX 40 series, showcasing the versatility of this technology.
The key feature of Reflex 2, known as Frame Wrap, significantly optimizes latency by ensuring that the frame the GPU produces is adjusted to include the most recent input. Essentially, once a frame is completed, Reflex 2 communicates with the CPU to ascertain the latest camera or mouse position, then warps the rendered image to match that input, thus enhancing the responsiveness of gameplay.
DSO Gaming notes that Frame Wrap operates optimally when frame rates exceed 100 FPS. However, users experiencing lower frame rates between 30 and 60 may encounter visual artifacts due to the significant disparity in movements across frames. Currently, it’s unclear whether the visual performance of Reflex 2 differs between the RTX 50 series and older models, but the ability for previous-generation cards to utilize this feature is a positive development. NVIDIA’s official plans regarding Reflex 2 support for GPUs prior to the RTX 50 series remain unknown.
