NVIDIA’s GeForce 590.26 Preview Driver now extends its AI-powered “Smooth Motion” frame generation feature to RTX 40-series (Ada Lovelace) GPUs—previously limited to RTX 50 cards. This software-level enhancement inserts an AI-generated frame between rendered frames in DX11, DX12, and Vulkan games that lack native DLSS Frame Generation, effectively doubling frame rates in some titles.

Users must download the preview driver via an NVIDIA Developer account and enable Smooth Motion using NVIDIA Profile Inspector. Early tests (e.g., on an RTX 4090 running World of Warcraft) showed FPS jump from 60 to 120, with notable, artifact-free gains. Similar benefits were observed in other titles like Company of Heroes 3.

However, this is still a preview: expect minor visual artifacts, occasional performance inconsistencies, and no resolution upscaling (unlike DLSS). Still, it offers a significant performance uplift for older or capped games without requiring game-level implementation.
