AMD Radeon owners can now access NVIDIA's DLSS 3.7 upscaling through a new unofficial mod called HelixSR 1.7.0. This update provides an option for users who prefer NVIDIA's image quality but cannot use the official software due to their hardware. The mod targets Direct3D 12 games on RDNA 1 and newer GPUs, including the RX 5000 series and later models. The mod may benefit users seeking improved visual fidelity in supported titles without upgrading their graphics card.
HelixSR 1.7.0 adds NVIDIA upscaling to AMD Radeon RDNA 1+ GPUs
The software, developed by lonewolf0622, utilizes a custom Direct3D 12 compute implementation to run DLSS 3.7's older Model E neural network. The mod uses a custom implementation to enable DLSS functionality on non-NVIDIA hardware. The developer has added Windows support to the existing Linux version, although they note that Windows functionality remains untested. The update allows a wider range of users to test the technology, although Windows stability remains unverified.
In a cited test, HelixSR delivered 91.4 FPS in Quality mode, which outperformed FSR 4.1.1's score of 72.1 FPS. The upscaling pass itself took 2.24 milliseconds, a speed that falls between FSR 3.1.5 at 0.91 milliseconds and FSR 4.1.1 at 5.07 milliseconds. The mod does not support NVIDIA's Frame Generation or Ray Reconstruction features, limiting it to basic resolution upscaling. We tracked a similar project where a modder ran DLSS 4.5 on AMD RX 9000 series GPUs using ZLUDA earlier while tracking Lonewolf0622 launches.
HelixSR 1.7.0 is closed-source software, but the developer has made installation scripts publicly available for users to deploy. The mod is designed for Direct3D 12 games and does not support Vulkan or OpenGL titles. The specific GPU and game used for the 91.4 FPS test were not identified, which leaves the exact performance context unclear. Users should verify that their GPU meets the RDNA 1 or newer requirement before installation.
The release demonstrates an attempt to bring NVIDIA upscaling features to AMD hardware. HelixSR 1.7.0 allows AMD users to utilize NVIDIA's neural network for upscaling. The project remains an unofficial mod with untested Windows support and missing test details. Installation relies on provided scripts, and users are advised to follow them carefully.
