The Witcher 3 gets unofficial DLSS 4.5 Multi Frame Generation mod

The Witcher 3 is more than a decade old, but modders are still finding ways to make it feel newer on modern hardware.

Modder PureDark has released an unofficial upscaler mod that adds NVIDIA DLSS 4.5 with Dynamic Multi Frame Generation to The Witcher 3: Wild Hunt. The mod is aimed at RTX 50 Series GPUs and can dramatically raise frame rates, especially when playing with ray tracing enabled.

The Witcher 3 did not launch with DLSS because the game originally released in 2015, years before NVIDIA introduced the technology. CD Projekt RED later added DLSS Super Resolution, Frame Generation, Reflex, and ray traced lighting features through the Next Generation update in 2022.

PureDark’s new mod goes further by replacing the game’s older Streamline 1.x implementation with Streamline 2.11.1. That matters because Multi Frame Generation needs a newer version of Streamline to work.

The mod supports both fixed and dynamic frame generation. Fixed mode lets players choose a 2x, 3x, 4x, or up to 6x frame multiplier. Dynamic mode adjusts the multiplier automatically depending on scene load and tries to match the display’s maximum refresh rate.

Testing on an RTX 5070 Ti with Ray Tracing Ultra settings showed large gains. A 30 FPS base could become 60 FPS at 2x, 90 FPS at 3x, and up to 180 FPS at 6x.

The higher multipliers are not perfect. Visual quality reportedly starts to fall apart above 3x, with artifacts around characters and UI elements. The 3x setting appears to be the best balance for now, offering a clear smoothness boost without making the image noticeably worse during normal gameplay.

The mod is currently available through PureDark’s Patreon, starting at the Supporter tier. Since this is an early build, some of the artifact issues may improve in later versions.

For players with RTX 50 Series cards, this is another way to revisit The Witcher 3 with smoother ray traced performance. It also shows how much life modding can add to older PC games, especially when official support stops short of the latest rendering features.

The Witcher 3 already received a strong next gen update, but this mod pushes it further for newer NVIDIA hardware. A ten year old RPG running with DLSS 4.5 Multi Frame Generation is a reminder of why the PC version still has such a long tail.
