If you own an RTX 20 series graphics card , you've probably already resigned yourself to the fact that NVIDIA has reserved DLSS Frame Generation exclusively for its newer models. It's a typical marketing ploy to force us to upgrade our hardware, but as always happens in the PC world, the modding community hasn't sat idly by and has found a way to bypass these official restrictions.
What we're seeing right now is a true display of technical ingenuity. We're no longer just talking about simple "bridges" that translate NVIDIA's code to AMD's, but projects that get the native DLSS-G pipeline running on Turing and Ampere architectures. Essentially, they've made 2018 hardware do things that the manufacturers themselves said were impossible, opening the door to a visual fluidity that was previously reserved for those who shelled out thousands of euros for a 40 or 50 series.
The dlssg_sm75 mod revolution and the native pipeline
One of the most important milestones is the dlssg_sm75 project , published on GitHub by modder Coldwood1026. Unlike previous attempts, this one doesn't use AMD's FSR 3 as an internal replacement. Instead, it directly modifies NVIDIA's official runtime (specifically nvngx_dlssg310.1 ), replacing the original kernels with recompiled versions for the RTX 20 series' SM75 architecture.
To prevent the system from rejecting the card, the mod tricks the software into identifying the GPU as an Ada Lovelace (RTX 40) during initialization. In real-world tests with The Witcher 3: Next-Gen , the frame generation switch was successfully activated, resulting in a genuine FPS increase and demonstrating that NVIDIA's code can run on older hardware if properly adapted.
Different tools for each generation: From Ada to Turing
The mod ecosystem has diversified to cover all price ranges. For 40-series users looking to go further, there's DLSSG-Transfusion . This project, spearheaded by TonyJoaca, unlocks multipliers of up to 6x, improving frame pacing consistency and reducing judder through temporal midpoint reconstruction.
On the other hand, gt2333588's NVIDIA MFG Bridge is a Swiss Army knife for RTX 20 and 30 series owners. This mod implements specific routing (SM75 for Turing and SM86 for Ampere) and allows you to choose between NVIDIA's native mode or AMD's FSR 3.1 mode. It even experiments with DLSS 5 Neural Rendering on the 30 series, emulating FP8 workloads using Ampere's FP16 Tensor Cores.
Actual performance and technical limitations
It's not all sunshine and roses, as we're talking about experimental software. On RTX 2060s, 2X mode usually works quite smoothly, but when you increase it to 3X, ghosting artifacts (trails in the image) start to appear, and 4X mode is still quite unstable. Furthermore, performance may be slightly lower than mods based on FSR 3, simply because the latter have been optimized for longer.
- Base FPS requirement: For a smooth experience and to avoid unbearable input lag, it is recommended to start with a base of at least 50-60 real FPS.
- VRAM consumption: Enabling frame generation increases the use of the video memoryTherefore, you have to be careful not to overload the card.
- Beware of Anti-Cheat: These mods work by intercepting DLLs, which can be detected as cheating in multiplayer games. Don't use them in competitive titles.
Practical Installation and Configuration
Getting started is usually simple: it involves downloading the nvngx.dll file or the corresponding DLL for the mod and renaming it (for example, to version.dll or dxgi.dll ) so that the game loads it on startup. The file should be placed in the same folder as the game's executable (.exe) file, not in the launcher.
In the case of MFG Bridge, you can create a dlssg_to_fsr3.ini file to force the multiplier selection menu to appear using the "Home" key within the game. It's crucial to remember that the game must natively support DLSS Frame Generation , as the mod doesn't inject the technology into games that lack it; instead, it intercepts existing calls to make it work on unsupported hardware.
This set of modifications demonstrates that the RTX 20 and 30 series hardware has hidden potential that NVIDIA has chosen to ignore. While stability varies depending on the game and multiplier, the ability to triple FPS in games like Cyberpunk 2077 or Black Myth: Wukong makes these tools a lifesaver for those who don't want to or can't upgrade their GPU right now.
