Earlier this year, Nvidia revealed a new feature called Smooth Motion – the answer to AMD’s driver-level AFMF frame generation. This feature is exclusive to the RTX 50-series cards, and as the name suggests, it’s designed to make gameplay smoother. It works by generating an extra frame between two traditionally rendered frames using AI. However, while it’s only available on the latest series, some users have found a way to use it on the previous RTX 40-series lineup.

When Smooth Motion was first announced, many RTX 40-series users were disappointed to learn they couldn’t use it. However, some users on the Guru3D forums have discovered a way to enable it on RTX 40-series cards, and the process is fairly simple.

Smooth Motion comes to the RTX 40 series (with a developer account)

First, if you haven’t done it already, you need to create an Nvidia Developer account, which you can do from here. Once that’s done, download the latest 590.26 developer driver and load a profile in the Nvidia Profile Inspector. Then, visit the Common settings tab, where you’ll find Smooth Motion. Although the Profile Inspector says the feature is only for RTX 50-series cards, user Macer on the Guru3D forum was able to enable it for their RTX 4090, and it worked perfectly.

The user tested the feature in World of Warcraft, and the results were impressive. With the feature turned off, they were getting around 82 FPS. After turning Smooth Motion on, the FPS jumped to 164. In short, it doubled the FPS. And since this is a driver-level solution, unlike DLSS, where specific support is needed, it can be used in a wide variety of games.

It is, however, important to keep in mind that some users might encounter performance issues after enabling Smooth Motion on their RTX 40-series cards. That’s because the setting officially supports only RTX 50-series cards at this time. Also, the Nvidia developer account gives access to pre-release software, so users won’t be using the final, stable version. In any case, if you do end up running into issues, just go back to the Nvidia Profile Inspector and disable Smooth Motion from there.
