Modders Unlock NVIDIA MFG on RTX 40, Then Get Blocked

What Is NVIDIA DLSS Multiframe Generation?

NVIDIA DLSS Multiframe Generation (MFG) is a frame generation technology that produces multiple interpolated frames from each rendered frame, significantly boosting perceived frame rates in supported games. It was introduced as an exclusive feature of the NVIDIA RTX 50 Series GPUs, which launched with the technology as a flagship selling point. The technology is part of NVIDIA's DLSS (Deep Learning Super Sampling) suite, which uses AI to enhance gaming performance and image quality. MFG solves the problem of limited frame rates in demanding titles by generating additional frames between rendered ones, reducing the computational load on the GPU.

In early September 2026, a group of modders successfully unlocked DLSS MFG to work on the previous-generation Ada Lovelace RTX 40 Series, circumventing NVIDIA's hardware restrictions. The modders rerouted and patched out the restrictions in memory, allowing NVIDIA's own DLSS-G MFG code to run on RTX 40 Series hardware. The first working version was demonstrated running Cyberpunk 2077 on RTX 40 Series GPUs. The mod is available via the GitHub repository MFGAdaUnlock-RenoDx.

Key Facts

NVIDIA DLSS Multiframe Generation was officially exclusive to RTX 50 Series GPUs until modders unlocked it for RTX 40 Series hardware in September 2026.

How Did Modders Unlock DLSS MFG on RTX 40 Series?

Modders unlocked DLSS MFG on RTX 40 Series by rerouting and patching out the memory restrictions that limited the technology to RTX 50 Series hardware, allowing NVIDIA's own DLSS-G MFG code to execute on Ada Lovelace architecture. The first working version was posted earlier in the week and demonstrated running Cyberpunk 2077 on RTX 40 Series GPUs.

Sebastian Castellanos, a user on X, commented on the mod's performance characteristics, noting that unless someone has both an RTX 40 Series and RTX 50 Series GPU to test the mod, they would be hard-pressed to tell the difference in performance. This suggests the modded implementation closely matches the native RTX 50 Series experience.

The DLSS MFG unlock mod for RTX 40 Series was first demonstrated running Cyberpunk 2077, with performance reportedly indistinguishable from native RTX 50 Series implementation.

How Did NVIDIA Block the DLSS MFG Unlock?

NVIDIA blocked the DLSS MFG unlock approximately 48 hours after the modders posted their successful attempts, pushing out an OTA update through the DLSS-G 310.9 update. The update renamed the temporal kernel and changed its descriptor layout, effectively locking out RTX 40 Series GPUs from using Multiframe Generation.

Sebastian Castellanos reported the block on X, stating:

"Update: NVIDIA apparently released an OTA update for DLSS FG/MFG/Streamline today and all the DLSS MFG unlock mods stopped working lol."

Users who had downloaded the original mod found that they could no longer use it after NVIDIA's OTA patch was applied.

NVIDIA's DLSS-G 310.9 OTA update, released approximately 48 hours after the mod appeared, renamed the temporal kernel and changed its descriptor layout to block RTX 40 Series GPUs from using Multiframe Generation.

How Did Modders Bypass NVIDIA's Block?

Modders released a fix to the block-out — version 0.4 — within the same day of NVIDIA's OTA patch. The update restored the Ada temporal-position correction and fixed the broken frame pacing or near duplicate generated frames at 3x and 4x multipliers.

Following the fix release, other users began testing the mod. Gaming Optimized, an X user, provided a how-to guide for enabling Multiframe Generation on an RTX 4060 GPU, testing it on Resident Evil Requiem and Forza Horizon 6. Gaming Optimized reported:

"I uploaded a video on how to enable DLSS Multi-Frame Generation on my RTX 4060 GPU. I tested RE9 and Forza Horizon 6. To be honest apart from the oblivious latency increase, it works extremely well!"

Modders released fix version 0.4 on the same day as NVIDIA's OTA block, restoring Ada temporal-position correction and fixing frame pacing issues at 3x and 4x multipliers.

Who Is This For?

This DLSS MFG unlock mod is intended for RTX 40 Series GPU owners who want to experience NVIDIA's Multiframe Generation technology without upgrading to an RTX 50 Series GPU. It is particularly relevant for users with mid-range RTX 40 Series cards such as the RTX 4060, as demonstrated in testing by Gaming Optimized.

The mod is also of interest to gaming enthusiasts and modding communities who follow the ongoing cat-and-mouse dynamic between NVIDIA's software restrictions and community-developed workarounds. However, users should be aware of potential latency increases, as noted in the RTX 4060 testing, and the possibility of future NVIDIA updates blocking the mod again.

The DLSS MFG unlock mod is designed for RTX 40 Series GPU owners who want access to NVIDIA's Multiframe Generation technology without upgrading to RTX 50 Series hardware.

Common Questions

Can DLSS Multiframe Generation run on RTX 40 Series GPUs?

Yes, through a community-developed mod. Modders successfully unlocked DLSS MFG on RTX 40 Series GPUs by patching memory restrictions, allowing NVIDIA's DLSS-G MFG code to run on Ada Lovelace architecture. The mod was demonstrated on an RTX 4060 running Resident Evil Requiem and Forza Horizon 6.

How did NVIDIA block the DLSS MFG unlock mod?

NVIDIA pushed an OTA update through DLSS-G 310.9 approximately 48 hours after the mod's release. The update renamed the temporal kernel and changed its descriptor layout, which locked out RTX 40 Series GPUs from using Multiframe Generation. Modders released fix version 0.4 the same day.

What games were tested with the DLSS MFG unlock mod?

The first working version of the mod was demonstrated running Cyberpunk 2077 on RTX 40 Series hardware. Subsequent testing by Gaming Optimized on an RTX 4060 included Resident Evil Requiem and Forza Horizon 6, with the user reporting the mod worked extremely well apart from a noticeable latency increase.
