Two community projects have unofficially brought NVIDIA's Smooth Motion frame-generation technology to GeForce RTX 30 GPUs. While NVIDIA officially supports Smooth Motion only on RTX 40- and RTX 50-series graphics cards, modders have shown that the driver-level technology can also run on RTX 30-series hardware.
NVIDIA Smooth Motion is a driver-level AI frame-interpolation technology that creates an additional frame between two rendered frames, making gameplay appear smoother.
Unlike DLSS Frame Generation, Smooth Motion can be applied to games without native frame-generation support. This is because it does not rely on game-engine-supplied motion vector data, making it work across a wider range of titles, including emulators.
The first project, dlssg_for_sm86-MFG-version, builds on an existing community-made compatibility layer that brought DLSS Frame Generation to RTX 30-series GPUs. Its latest version expands that work by adding support for NVIDIA Smooth Motion, which can be enabled through NVIDIA Profile Inspector on Ampere hardware.
The project uses a proxy DLL placed alongside the game's rendering executable and also adds Vulkan support to the existing DLSS-G compatibility layer. Testing has confirmed Smooth Motion on an RTX 3070, with additional RTX 3080 testing showing the feature working in several games and emulators. However, users have also reported compatibility issues and visual artifacts.
The second project, NVSmooth30 by ItsAdeline, takes a different approach with a clean-room compatibility layer designed to run NVIDIA's existing NvPresent64.dll Smooth Motion path on Ampere hardware.
Rather than extending the existing DLSS-G mod, it patches GPU capability checks, intercepts the CUDA loading path, and retargets compatible SM89 kernels for SM86 hardware used by RTX 30-series GPUs. It also includes an experimental DirectX 11-to-DirectX 12 presentation bridge.
NVSmooth30 was first demonstrated on an RTX 3050 Laptop GPU, while another user has reported getting it working on an RTX 3070. The developer describes the project as experimental, with compatibility still being tested across different GPUs, games, and driver versions.

Despite the successful demonstrations, both projects remain unofficial and experimental, with compatibility varying across games and hardware. Crashes, visual artifacts, and potential anti-cheat conflicts show that the implementations still need refinement. For now, it's more reasonable to try these mods with single-player games.
