NVIDIA’s Smooth Motion is unofficially up and running on GeForce RTX 40 series GPUs thanks to the preview driver 590.26 – and the early results are turning heads. 
Though it’s designed for the upcoming RTX 50 series, crafty users have managed to enable it on RTX 40 cards like the 4070 Ti with some driver tweaks and the help of NVIDIA Profile Inspector.
This driver-level feature acts similarly to AMD’s Fluid Motion by interpolating frames without the need for DLSS integration. While it doesn’t quite match the power of Frame Generation or Multi-Frame Generation, it offers an appealing middle ground for boosting performance in many games.
One benchmark from YouTube’s First Ever channel showed PUBG gaining up to a 60% FPS improvement with Smooth Motion on a GeForce RTX 4070 Ti, pushing gameplay from low triple digits to a buttery-smooth experience. Although there’s a minor bump in render latency, the overall responsiveness is reportedly still solid – though some users remind us that render latency isn’t the full story. Total system latency is the metric to watch.
Early adopters are also seeing uplift in games like Deep Rock Galactic Survivor, but the feature isn’t without its caveats. Some players report bugs, stuttering, or the feature not enabling at all. Workarounds like updating RTSS to v7.3.7 Beta 6 for MSI Afterburner users seem to fix some issues.
As of now, Smooth Motion is an unofficial party trick – unofficial, unstable, and irresistible to enthusiasts. It might not be the final form of NVIDIA’s motion tech, but it’s a tempting glimpse of what’s ahead for RTX 50 series users and a nice bonus for RTX 40 owners willing to get their hands a bit dirty.
