DLSS 5 Modding Expands Support to Older NVIDIA RTX GPUs
The ongoing development and distribution of the leaked DLSS 5 DLL has led to significant advancements in compatibility, now reaching NVIDIA’s RTX 20-series "Turing" GPUs. This is notable, as Turing is three generations behind the latest "Blackwell" architecture that NVIDIA officially recommends for DLSS 5. The modding community, undeterred by these generational gaps, continues to push the boundaries of what’s possible with NVIDIA’s AI-powered upscaling technology.
Community-Driven DLSS 5 Builds for Legacy Hardware
Developer ShortFuse has released new DLSS-NR builds specifically targeting older RTX hardware. Among these is a "speed boost" build designed for the RTX 20-series, aiming to improve performance on these aging GPUs. However, results remain inconsistent. While some games, such as the original Red Dead Redemption, reportedly run with DLSS 5 enabled, others like Red Dead Redemption 2 fail to initialize. Hogwarts Legacy becomes stuck in a standby state, and GTA 5 only manages to run for a brief period before the display signal drops.
FP16 Implementation Improves Performance on Turing and Ampere
The community has also made strides in optimizing DLSS 5 for older architectures. According to X user @DystopianSuns, DLSS 5 is now running on both RTX 20 and RTX 30 GPUs using an FP16 (16-bit floating point) implementation. This marks a shift from the earlier FP8 approach, which significantly hindered performance on Ampere-based cards. Since neither Turing nor Ampere architectures accelerate FP8 as efficiently as Blackwell, the move to FP16 has resulted in more stable and respectable performance across a range of titles.
Reports from the RenoDX Discord indicate that RTX 30-series users are experiencing solid results in various games. Notably, DLSS 5 has even been enabled in Manhunt running through the PS2 emulator PCSX2, and testers have confirmed functionality in older DirectX 9 and DirectX 11 titles—well beyond the APIs officially supported by NVIDIA for DLSS 5.
DLSS 5’s Unofficial Expansion and Future Prospects
The current state of DLSS 5 modding is far from finalized. The movement began when a precursor to DLSS 5 leaked alongside NBA 2K27, sparking a wave of community-driven innovation. Modders quickly adapted DLSS 5 for RTX 40-series cards, and the technology has since proliferated to even older hardware.
NVIDIA has yet to confirm which GPU generations will receive official DLSS 5 support when the feature launches later this year. However, the rapid progress made by the modding community suggests that broader compatibility could be on the horizon. As enthusiasts continue to experiment and share their findings, the potential for DLSS 5 to enhance gaming experiences on a wide range of RTX GPUs grows ever more promising.
