Modder gets DLSS Neural Rendering working on AMD RDNA 4 GPUs

A modder has successfully ported Nvidia DLSS 5 Neural Rendering to AMD GPUs for the first time. Created by developer danielblnc, the DLSS-NR for AMD tool enables RDNA 4 graphics cards to run Nvidia's neural rendering model in supported DirectX 12 games via a custom installer and Nvidia's nvngx_dlssnr.dll.

As shown by Ancient Gameplays, the modification operates by placing the installer and DLL file into a game's bin directory, with neural rendering toggled through an FSR 3 or FSR 4 profile. Testing has confirmed compatibility with Cyberpunk 2077 and GTA V: Enhanced, though older AMD architectures remain unsupported. Additionally, anti-cheat software blocks the DLL entirely, limiting usage strictly to single-player titles.

According to benchmarks from the youtuber, performance penalties are significant on AMD hardware. Initial builds on a Radeon RX 9070 XT dropped frame rates in Cyberpunk 2077 at 1080p from over 80FPS down to 11-12FPS. However, the modder has since released an update that says it increases performance by roughly 12%.

This is only possible because DLSS 5 uses FP8 math, which AMD's RDNA 4 architecture natively supports alongside Nvidia's RTX 40-series and RTX 50-series GPUs. Nvidia originally positioned DLSS 5 as exclusive to Blackwell hardware, though modders previously enabled it on RTX 30-series and RTX 40-series cards.

KitGuru says: While the unofficial AMD implementation remains impractical for everyday gameplay, it shows that DLSS can be used on AMD graphics cards.
