Universal MFG Unlocker 1.6.1 为所有 RTX GPU 带来实时 DLSS 预设切换

Universal MFG Unlocker, the increasingly popular community-developed utility from modder dashdogy, has received another substantial update. The newly released version 1.6.1 introduces real-time DLSS preset switching across NVIDIA's entire GeForce RTX lineup, spanning the RTX 20, 30, 40, and 50 Series, alongside further compatibility improvements.

As we previously reported, the modding community has successfully brought NVIDIA's officially RTX 50-exclusive DLSS Multi Frame Generation technology to older RTX 40, 30, and even 20 Series GPUs through several independent projects. Dashdogy's original RTX40MFG-Unlock was among the earliest and most advanced implementations for Ada Lovelace, while separate projects from sdli1995 and Coldwood1026 targeted Ampere and Turing GPUs, respectively.

The Universal MFG Unlocker interface displays version 'V1.6.1' with features including DLSS preset switching for RTX 50, 30, and 20 series, and added support for RTX 50 series.

Since then, dashdogy's project has evolved into the more comprehensive Universal MFG Unlocker, with version 1.5.0 introducing NVIDIA's faster DLSS Frame Generation Preset C alongside Intel XeSS Multi Frame Generation support through OptiScaler. Now, version 1.6.1 takes things a step further by making DLSS model experimentation considerably more convenient.

Specifically, the utility allows users to switch between DLSS Super Resolution Presets J, K, L, and M, Ray Reconstruction Presets D, E, and F, and Frame Generation Presets A, B, and C directly through an in-game menu. These changes take effect immediately in supported DirectX 12 games without requiring a full restart, although switching Frame Generation presets restarts Frame Generation itself briefly. The functionality debuted on RTX 40 GPUs with version 1.6.0 and has now been extended to the RTX 20, 30, and 50 Series.

We also conducted some hands-on testing on a laptop equipped with an RTX 4060 Laptop GPU, confirming that the tool works as advertised:

A screen from The Witcher 3: Wild Hunt shows a settings modification panel for DLSS Super Resolution with 'SR preset' set to 'Preset M_override supplied' and an NPC character labeled 'Talk: Boatwright.' — *Super Resolution preset override demonstrated as working.*

A scene from The Witcher 3 shows the MFG Unlocker 1.6.1 interface with 'DLSS-G preset' set to 'Preset C (performance)' and 'DLSS Ray Reconstruction' using 'Preset F,' while a character labeled Talk Boatwright is beside a boat. — *Super Resolution preset override demonstrated as working.*

This is an incredibly useful addition, particularly for the technology press, content creators, hardware reviewers, and enthusiasts who regularly evaluate NVIDIA's various DLSS models. Previously, comparing different presets typically involved modifying overrides through the NVIDIA App, restarting the game, and attempting to reproduce identical gameplay sequences. Real-time switching eliminates much of that inconvenience, making direct visual comparisons and performance testing significantly easier.

For instance, users can quickly examine the image quality, temporal stability, ghosting, and performance differences between the first-generation Transformer-based Preset K and the newer Presets L and M introduced with DLSS 4.5. Likewise, evaluating the different Ray Reconstruction and Frame Generation models becomes considerably more straightforward.

Considering how frequently NVIDIA updates its DLSS technologies, we sincerely hope the company eventually incorporates comparable real-time preset switching functionality directly into the NVIDIA App. Although the application already offers extensive DLSS overrides, a proper in-game interface with instant model switching would represent a welcome quality-of-life improvement for reviewers and enthusiasts alike.

A settings menu titled 'DLSS Override - Model Presets' displays options for Frame Generation, Super Resolution, and Ray Reconstruction, with 'Apply' and 'Cancel' buttons. — *While the NVIDIA App already allows users to switch between DLSS presets, the process remains unnecessarily cumbersome, particularly for real-time performance testing and image quality comparisons.*

Beyond preset switching, version 1.6.1 introduces expanded RTX 50 Series support, including MFG controls, Dynamic MFG settings, a Reflex FPS limiter, and FPS monitoring. It also fixes an issue preventing Frame Generation from being enabled on certain RTX 20 and 30 Series configurations and improves XeSS Multi Frame Generation compatibility.

The mod remains experimental, particularly on older RTX generations, and live preset switching is currently limited to supported DirectX 12 implementations. Vulkan titles and certain older Frame Generation versions still require a game restart.

Interested users can download Universal MFG Unlocker 1.6.1 from GitHub. Its built-in menu can be accessed using the Backspace key without requiring additional interface software.
