Modders Enable DLSS Frame Generation on NVIDIA RTX 20-Series GPUs
Recent developments in the PC gaming community have brought NVIDIA’s DLSS Frame Generation technology to GeForce RTX 20-series graphics cards, a feature previously unavailable on these GPUs. This breakthrough was achieved by a modder who successfully enabled DLSS Frame Generation on an RTX 2060 Max-Q while playing The Witcher 3 next-gen update using DirectX 12. The in-game Frame Generation toggle became accessible, and users observed a noticeable improvement in framerate.
DLSS Frame Generation: Official Support and Modding Efforts
NVIDIA officially restricts DLSS Multi Frame Generation (MFG) to its latest RTX 50-series GPUs, while standard Frame Generation is only supported on RTX 40-series and newer cards. Previous modding efforts had already brought DLSS Frame Generation to RTX 30-series GPUs, but this new project extends compatibility to the Turing-based SM75 architecture found in the RTX 20-series.
Unlike earlier mods that routed DLSS Frame Generation through AMD’s FSR 3 pipeline, this latest approach utilizes NVIDIA’s own nvngx_dlssg 310.1 runtime. The mod replaces the original GPU kernels with versions compiled specifically for SM75 and modifies architecture checks, allowing the runtime to recognize the Turing GPU as an Ada Lovelace model. This enables the initialization of DLSS Frame Generation on hardware that NVIDIA does not officially support.
Performance and Compatibility Observations
Initial user reports indicate mixed results. One Reddit user with an RTX 2060 noted that 2X Frame Generation mode works reliably, but 3X mode introduces ghosting artifacts, and 4X mode is unstable. Performance was also reported to be slightly lower compared to AMD’s FSR Frame Generation on the same hardware. Other users have mentioned compatibility issues, suggesting that the mod is still in an experimental phase and may not be stable across all systems.
It is important to recognize that these findings are based on a limited number of user experiences. Broader testing will be necessary to determine the mod’s reliability and performance across different games and hardware configurations.
Implications for NVIDIA RTX Users
This modding achievement highlights the potential for advanced features like DLSS Frame Generation to run on older RTX GPUs, raising questions about the limitations set by official support. While the mod is not yet fully polished, it demonstrates the ongoing innovation within the PC gaming community and the possibilities for extending the lifespan and capabilities of existing hardware.
