Universal MFG Unlocker 1.6.1 Brings Real-Time DLSS Preset Switching to RTX 20, 30, 40, and 50 GPUs
Universal MFG Unlocker, the community-made utility from modder dashdogy, has received another major update, and version 1.6.1 is one of its most useful releases yet. The tool now supports real-time DLSS preset switching across NVIDIA’s GeForce RTX 20, RTX 30, RTX 40, and RTX 50 Series graphics cards, making it much easier for PC gamers, reviewers, and hardware enthusiasts to compare different DLSS models inside supported games.
The biggest highlight of Universal MFG Unlocker 1.6.1 is the ability to change DLSS presets directly from an in-game menu. Instead of closing a game, adjusting settings through external tools, and restarting everything to test a different DLSS model, users can now switch presets on the fly in supported DirectX 12 titles.
This is especially important for anyone testing NVIDIA DLSS image quality, frame generation behavior, ray reconstruction, ghosting, temporal stability, and performance differences between models.
The new update supports real-time switching for several DLSS components, including DLSS Super Resolution Presets J, K, L, and M, Ray Reconstruction Presets D, E, and F, and Frame Generation Presets A, B, and C.
These changes apply immediately in supported DirectX 12 games. When switching Frame Generation presets, Frame Generation briefly restarts, but the game itself does not need to be fully restarted in most supported cases.
Universal MFG Unlocker originally gained attention for bringing newer NVIDIA frame generation capabilities to older RTX graphics cards through community-driven work. NVIDIA’s latest DLSS Multi Frame Generation technology is officially associated with newer RTX hardware, but modders have been experimenting with ways to enable related functionality on previous RTX generations.
Dashdogy’s earlier work focused on RTX 40 Series GPUs, but Universal MFG Unlocker has since grown into a broader tool with support for RTX 20, RTX 30, RTX 40, and RTX 50 Series cards. Version 1.5.0 previously introduced NVIDIA’s faster DLSS Frame Generation Preset C and added Intel XeSS Multi Frame Generation support through OptiScaler. With version 1.6.1, the focus is now on convenience, compatibility, and faster testing.
For players, this update means more control over how DLSS behaves in supported games. For reviewers and content creators, it could save a huge amount of time. In the past, comparing DLSS presets often required changing overrides, restarting the game, loading the same scene again, and trying to recreate identical test conditions. That process was slow and inconsistent.
With real-time preset switching, users can stand in the same in-game location and quickly compare multiple DLSS models under nearly identical conditions. This makes it much easier to spot differences in sharpness, motion clarity, artifacts, flickering, ghosting, and frame pacing.
For example, users can compare NVIDIA’s earlier Transformer-based Preset K against newer Presets L and M introduced with later DLSS updates. They can also test different Ray Reconstruction models to see which one produces the cleanest lighting, reflections, and denoising in supported titles. Frame Generation presets can also be evaluated more quickly, helping users determine which option feels smoother or performs better on their system.
Universal MFG Unlocker 1.6.1 also expands RTX 50 Series support. The update adds Multi Frame Generation controls, Dynamic MFG settings, Reflex FPS limiter support, and FPS monitoring for newer NVIDIA GPUs. These additions make the tool more complete for users experimenting with advanced DLSS and frame generation settings.
The update also fixes an issue that prevented Frame Generation from being enabled on some RTX 20 and RTX 30 Series configurations. That fix should make the utility more reliable for users on older RTX hardware. XeSS Multi Frame Generation compatibility has also been improved, giving users more flexibility beyond NVIDIA’s own DLSS ecosystem.
There are still some limitations. Universal MFG Unlocker remains experimental, especially when used on older RTX graphics cards. Real-time DLSS preset switching currently depends on supported DirectX 12 implementations. Vulkan games and some older Frame Generation versions may still require a full game restart before changes take effect.
Even with those limitations, Universal MFG Unlocker 1.6.1 is a major step forward for DLSS testing and customization. NVIDIA’s official app already offers DLSS override options, but the process is not as fast or convenient as switching models directly in-game. A built-in real-time DLSS preset menu from NVIDIA would be a welcome feature in the future, especially for users who frequently compare visual quality and performance.
For now, Universal MFG Unlocker fills that gap with a practical and powerful solution. The built-in menu can be opened with the Backspace key, and no additional interface software is required. Users interested in trying the tool can find Universal MFG Unlocker 1.6.1 through its official project repository.
For PC gamers who enjoy tuning graphics settings, testing DLSS image quality, or pushing older RTX hardware beyond its standard feature set, Universal MFG Unlocker 1.6.1 is one of the most interesting community tools currently available.
