Modders Gets NVIDIA DLSS Running On Radeon RX 7000 Series GPUs
AI-summarised brief · reviewed before publication
A modding project named d4r, short for “DLSS 4 Radeon,” has enabled NVIDIA’s older DLSS models (3 CNN, 4, and 4.5) to run on AMD Radeon RX 7000 Series GPUs under Linux and Proton. The effort uses ZLUDA to translate CUDA calls to AMD hardware, routing through a Wine bridge and the official DLSS DLLs without modifying the library. Demonstrations on a Radeon RX 7700 XT running Silent Hill at 2560×1440 show performance ranging from 69 fps (DLSS 4 Quality) to 90 fps (DLSS 4.5 Ultra Performance), with native FSR 4 still outperforming all DLSS variants. NVIDIA has stated it does not endorse the project.
💡 Why It Matters
- · The breakthrough demonstrates that proprietary NVIDIA upscaling can be repurposed for AMD hardware, potentially leveling the competitive field for gamers who prefer or only own Radeon GPUs.
- · It also signals a growing trend of cross‑platform compatibility hacks that challenge vendor‑locked ecosystems.
