Nvidia's Smooth Motion technology, similar to AMD's Fluid Motion Frames, will be available for the RTX 4000 series GPUs in a future update.
Smooth Motion allows Frame Generation to be used in DX11 and DX12 games via driver settings, without needing developer implementation.
While Smooth Motion may not offer the same image quality and input latency as Frame Generation, it is beneficial for older games without native support.
Nvidia's move to make Smooth Motion accessible to older GPUs shows an effort to offer features across multiple GPU generations.
