Nvidia has failed to block user-made mods that enable DLSS Multi-Frame Generation on its previous-generation RTX 40 series graphics cards, with community developers restoring support across multiple games within hours of an app update that attempted to stop them. The mods unlock a feature that Nvidia has repeatedly stated is exclusive to its newer Blackwell architecture, specifically the RTX 50 series. The development affects owners of RTX 40 series GPUs in the US and elsewhere who have been told the hardware cannot support the technology.
At Blackwell’s launch, Nvidia said Multi-Frame Generation was impossible on RTX 40 series cards because those GPUs use a hardware optical flow generator that cannot produce multiple interpolated frames per rendered frame. Blackwell instead uses a software-based optical flow method that runs on shader cores. Modders have now demonstrated that the software method can be used on Ada Lovelace GPUs, bypassing the older hardware unit entirely by using Nvidia’s own DLSS-G framework.
At least three distinct mods have emerged to unlock the feature. One began as a Cyberpunk 2077 mod by a creator named dashdogy, relying on game-specific modding frameworks, and was later adapted into a broader ReShade plugin applicable to almost any game. Another multi-game unlock mod exists, and a third was found as well. Users on X and Reddit report the mods work and deliver surprisingly smooth frame pacing. dashdogy noted his mod backports Blackwell-specific frame timing instructions to allow Ada GPUs to place frames in correct positions, suggesting the hardware dependency was exaggerated.
One public test of the mod came from a user named Castellanos, who posted a video on September 4 showing DLSS Multi-Frame Generation enabled on an RTX 4060 GPU in RE9 and Forza Horizon 6. Castellanos said the feature works extremely well apart from an obvious latency increase. The mod developers have also released at least two more updates in the ten hours following that post, responding to roadblocks thrown up by Nvidia’s latest app update. A reporter for Tom’s Hardware could not get the mod working before publication but confirmed the community activity.
Earlier attempts to enable the feature on RTX 40 series cards used GPU spoofing or hybrid solutions, such as combining standard 2x DLSS Frame Generation with AMD’s FSR 3 or Lossless Scaling software frame generation. Those workarounds were clunkier than the current native game mods. The new mods rely on Nvidia’s own software framework and are broadly applicable rather than limited to a single title.
This event coincides with the rollout of DLSS 5 “Neural Rendering,” another technology initially pitched as an RTX 50 series exclusive. Nvidia reversed that position and promised Neural Rendering for RTX 40 series cards as well, a shift that may have been driven by hackers porting the technology not just to older Nvidia architectures but also to AMD Radeon GPUs. Once it became known that DLSS 5 runs on non-Blackwell hardware, maintaining hardware exclusivity claims risked losing consumer trust.
Whether Nvidia will similarly pivot on Multi-Frame Generation for RTX 40 series remains open. The company has shown no interest in enabling the feature through official channels, and its marketing narrative continues to state the technology does not work on those cards. User reports contradict that claim, and the modding community has demonstrated it is technically possible. Nvidia has not commented on the mods or the app update.
