HelixSR Brings DLSS 3.7 to Steam Deck and AMD Handhelds

The HelixSR mod brings NVIDIA’s DLSS upscaling to the Steam Deck and other AMD-powered handhelds, according to Wccftech. The report says the mod runs NVIDIA’s technology on AMD GPUs.

Released on GitHub by developer lonewolf0622, HelixSR is described as a drop-in replacement for AMD’s FSR 3.1 upscaler on Direct3D 12. It uses Preset E, which the developer calls Model E and which arrived with DLSS 3.7.

DLSS 3.7 was the last version of NVIDIA’s CNN-based model before the company moved to Transformer models with DLSS 4, the report says. Wccftech characterizes the CNN model as a good fit for handhelds.

The source says HelixSR ran faster than FSR 4 in early tests, but the supplied material does not include benchmark figures or testing details. It also does not specify which Steam Deck models or other handhelds were tested.
