NVIDIA DLSS 4 Multi Frame Gen may one day come to the RTX 40 series GPUs

One of the biggest features of the Blackwell RTX 50 series GPUs is Multi Frame Gen (MFG in short). This feature is exclusive to the RTX 50 series. However, NVIDIA claims that this tech may one day come to the RTX 40 series GPUs.

In an interview with Digital Foundry, NVIDIA’s Bryan Catanzaro stated that NVIDIA may bring DLSS 4 MFG to the RTX 40 series GPUs in the future. When asked why DLSS 4 Multi Frame Gen is exclusive to the RTX 50 series GPUs, Catanzaro had this to say.

“I think this is primarily a question of optimization and also engineering and then the ultimate user experience. So, you know, we are launching this Frame Generation, the best multi-frame generation technology with the 50 series, and we’ll see what we are able to squeeze out of older hardware in the future.”

A small note here. In the interview, Alex asked about MFG coming to the RTX 30 series. However, I’m certain he meant the RTX 40 series. After all, the RTX 30 series never supported Frame Generation. [UPDATE: Or not. The new Frame Gen does not use the hardware Optical Flow accelerator. Instead, DLSS 4 Frame Gen uses the Transformer AI model. So, in theory, it should also work with the RTX 30 series.]

This falls in line with what NVIDIA has told the press. The main reason Multi-Frame Gen is exclusive to the RTX 50 series is because on the Blackwell GPUs, the hit of MFG in input latency is small when going from X2 to X4. This is a crucial thing for MFG.

We’ll talk more about DLSS 4 Multi-Frame Gen in a few days. All I can say right now is that NVIDIA will have its hands full with further optimizations for the RTX 50 series. So, don’t expect them to make it available to the RTX 40 series in the foreseeable future. It may happen one day. However, it won’t be soon.

To be honest, I don’t expect MFG to ever become available on the RTX 40 series. This feels more like a PR statement, similar to the one we got about Frame Generation on the RTX 30 series GPUs. When NVIDIA launched the RTX 40 series, it stated that it might one day bring this feature to the RTX 30 series. And, as you know, this hasn’t happened.

I’m merely speculating here, but there is no benefit for NVIDIA to go into all the trouble of optimizing MFG for its older GPUs. This tech was created for the Blackwell GPUs. And I know, this may be a bummer for some. However, this feature is not something that NVIDIA promised for the RTX 40 series. So, you can’t say that they’ve deceived you. It sucks. But then again, that’s what AMD may be also doing with FSR 4.0.

Stay tuned for more!
