NVIDIA RTX 20-Series "Ampere" GPUs Can Now Run DLSS Frame Generation Through Mods

A modder has gotten NVIDIA's DLSS Frame Generation running on a GeForce RTX 20-series GPU, tested on an RTX 2060 Max-Q in The Witcher 3's next-gen update using DirectX 12, where the in-game Frame Generation toggle could be switched on and an improved framerate was observed. NVIDIA officially supports simple Frame Generation only on RTX 40-series and above, and DLSS Multi Frame Generation only on RTX 50-series GPUs. The mod adapts earlier RTX 30-series work to Turing's SM75 architecture, running NVIDIA's actual nvngx_dlssg 310.1 runtime by swapping GPU kernels for SM75-compiled versions and tweaking architecture checks so the runtime reads the Turing GPU as Ada Lovelace.

Shortly after modders enabled DLSS 5 on previous NVIDIA generations https://www.techpowerup.com/352147/leaked-dlss-5-reaches-rtx-30-series-ampere-gpus-but-performance-falls-apart , the focus has shifted to Frame Generation. A modder has reportedly gotten NVIDIA's own DLSS Frame Generation running on a GeForce RTX 20-series GPU, something the company has never officially supported. The mod was tested on an RTX 2060 Max-Q in The Witcher 3's next-gen update using DirectX 12, where the in-game Frame Generation toggle could be switched on, and the improved framerate was observed. NVIDIA officially only supports DLSS Multi Frame Generation MFG on RTX 50-series GPUs https://www.techpowerup.com/347894/nvidia-dlss-4-5-dynamic-multi-frame-generation-and-6x-mode-officially-arrive , with simple Frame Generation limited to RTX 40-series https://www.techpowerup.com/299058/nvidia-introduces-dlss-3-with-breakthrough-ai-powered-frame-generation-for-up-to-4x-performance?cp=2 and above. This mod builds on earlier work that brought DLSS Frame Generation to RTX 30-series GPUs https://www.techpowerup.com/352508/modders-unlock-dlss-multi-frame-generation-for-rtx-30-series-ampere-gpus . That project has now been adapted to support yet another generation, targeting Turing's SM75 architecture. Unlike previous RTX 20 and RTX 30 mods, which rerouted DLSS Frame Generation calls through AMD's FSR 3 pipeline, this one runs NVIDIA's actual nvngx dlssg 310.1 runtime. It swaps out the original GPU kernels for versions compiled for SM75 and tweaks architecture checks so the runtime reads the Turing GPU as Ada Lovelace, letting it initialize.
