THE CRUNCH
Modders have ported NVIDIA's Smooth Motion frame generation to Ampere cards, bypassing the feature's official RTX 40-series-only status. Two independent projects are making this possible. One builds on an existing DLSS-G runtime adaptation, while the other creates a clean-room compatibility layer targeting a specific driver path. Both have reportedly been tested on RTX 3070 and RTX 3050 laptop GPUs.
The feature, officially known as Smooth Motion, is a driver-level frame generation technology similar to AMD's AFMF. It is currently exclusive to RTX 40-series and newer cards through the NVIDIA App. Ampere owners have been left out of this officially, but two separate efforts are working to close that gap. One project, dlssg_for_sm86, expands on a previous adaptation of NVIDIA's DLSS-G runtime for the SM86 architecture used by RTX 30 GPUs. The update adds Smooth Motion and Vulkan support. The second project, NVSmooth30, takes a different approach by creating a clean-room compatibility layer aimed directly at NVIDIA's NvPresent64.dll Smooth Motion path.
The dlssg_for_sm86 update reportedly went live on September 19 and has been tested on an RTX 3070. NVSmooth30, developed by a user going by ItsAdeline, has been tested on an RTX 3050 laptop GPU and separately on an RTX 3070. These are early, unverified implementations. The modding community is effectively filling a feature gap left by NVIDIA's current driver strategy.
Why It Matters: This development highlights a growing trend of community-driven feature restoration. It allows owners of older hardware to access modern performance-enhancing technologies without waiting for official support or a hardware refresh.
