Modders Bring Nvidia Smooth Motion Frame Generation to RTX 3000 Series GPUs

The mod, called NVSmooth30, is published on GitHub and has been confirmed to work on an RTX 3050 laptop and an RTX 3080 desktop GPU, TechRadar reported, citing coverage by Wccftech. Smooth Motion is Nvidia's equivalent of AMD's Fluid Motion Frames: it generates frames at the driver level in games that lack official support for the technology, a tool that is most useful for older titles and games running in emulators.

According to the mod's creator, NVSmooth30 works by modifying Nvidia's driver-level frame generation DLL file, labeled NvPresent64, which bypasses the compatibility checks that would normally prevent the function from running on Ampere hardware. The modification also relies on what the creator describes as conservative metadata retargeting from Ada Lovelace, the architecture behind the RTX 4000 series, toward Ampere.

Installation is described as simple: users place the DLL file in the relevant game's folder and enable Smooth Motion through the Nvidia Profile Inspector application. The creator warns the project is experimental, so it carries a risk of game bugs, crashes and other issues. It must not be used in online games that run anti-cheat software, because doing so could result in a ban.

The mod arrives as GPU prices remain elevated. TechRadar reported that the graphics card market is in disarray because of a memory crisis, leaving cards from both Nvidia and AMD Radeon too expensive for many PC owners to consider an upgrade. Features such as Multi-Frame Generation, Dynamic Frame Generation and Smooth Motion are ones those users would like to run, but cannot use on older hardware.

Modders have repeatedly shown that such features can be backported in some form. Previous efforts have gone as far as porting DLSS 5 onto the RTX 4080, though with a performance cost. Nvidia demonstrated DLSS 5 Neural Rendering at Gamescom 2026. Bringing that technology to older cards in the near term is unrealistic; Nvidia previously told TechRadar that it does plan to add backward compatibility at some point, with 4000-series models likely to receive it first and 3000-series support a later, less certain possibility.

Smooth Motion in particular has drawn backporting attention because many users are still running older GPUs. Official support would reduce reliance on unofficial mods for better performance on GeForce hardware. Nvidia has not officially implemented Smooth Motion on RTX 3000 series cards.
