An independent mod called HelixSR is allowing AMD GPUs — including the Steam Deck and RDNA 2/3 handhelds — to run DLSS 3.7 (Model E / Preset E) neural reconstruction without an NVIDIA GPU, NVIDIA drivers, CUDA, or ROCm.
Developed by lonewolf0622, it acts as a drop-in replacement or backend for FSR 3.1 in Direct3D 12 games. The game communicates as if using FSR, but the upscaling step runs the DLSS network via standard compute shaders. It is not a newly trained model; it is NVIDIA's official network running on different hardware.
What version 1.8.0 changed
Released on October 11, 2026 on GitHub, version 1.8.0 embeds the network directly in the DLL (single file), simplifies setup with f/o/n options, and includes an uninstaller. The script downloads NVIDIA's official DLL (DLSS 310.7.0), builds the network locally, and removes the original file. The developer recommends falling back to 1.4.3 if 1.8.0 fails and asks for logs on issues.
Support: AMD RDNA 1 or newer, Linux (Proton) and Windows. Primarily tested on the BC-250; other hardware relies on community reports. A Decky plugin for Steam Deck simplifies installation in Gaming Mode.
Performance and limitations
Early community-reported tests show lower frame times than FSR 4 in some Steam Deck scenarios (e.g., ~3.5 ms vs ~4.5 ms at 800p). Image quality is typically better than FSR 3 and close to or slightly below FSR 4 in some aspects, with generally lower performance cost than FSR 4 on hardware without dedicated acceleration. The project is unofficial, not affiliated with NVIDIA, AMD, or OptiScaler, and the generated DLLs contain NVIDIA property — they must not be redistributed.
Clear limitations: Direct3D 12 only, super resolution only (game or OptiScaler frame generation continues to work), and Vega is unsupported. Results vary; the developer does not guarantee universal compatibility.
Why it matters
For owners of Steam Deck, ROG Ally, and older Radeon cards, HelixSR offers an image-quality alternative that does not rely solely on official FSR, which in earlier generations often shows more shimmer and artifacts. It is an example of the community continuing to work around proprietary hardware barriers in neural upscaling.
