HelixSR Mod Brings DLSS 3.7 to the Steam Deck and AMD Handhelds, Running Faster Than FSR 4 in Early Tests

A new mod is giving the Steam Deck and other AMD-powered handhelds something they were never supposed to have: NVIDIA's DLSS (Deep Learning Super Sampling) upscaling. HelixSR, released two days ago on GitHub by developer lonewolf0622, is a drop-in replacement for AMD's FSR 3.1 upscaler on Direct3D 12 that runs NVIDIA's DLSS neural network on AMD GPUs instead. Specifically, it uses Preset E (which the developer calls Model E), introduced with DLSS 3.7, the final iteration of DLSS's CNN-based model before NVIDIA switched to Transformer models with DLSS 4.
