Nvidia GeForce RTX 40 series GPU owners are in a pretty good place right now. First of all, the new 50 series doesn’t really provide a compelling argument to upgrade, especially with ongoing stock issues and price hikes for the RTX 5090, RTX 5080, and newly launched RTX 5070 Ti.

On top of that, the 40 series is doing just fine and has even benefitted from DLSS 4 upgrades that affect all RTX GPUs. One feature that Nvidia has been keen to show off for the 50 series is Multi Frame Generation (MFG) – a natural progression of the single-frame-gen available on the last-gen cards. However, someone has already reportedly cracked the code to get MFG on the 40 series.

RTX 4080 seems to support Multi Frame Generation with a crack

First thing first, Multi Frame Generation is exclusive to Nvidia’s RTX 50 series GPUs. However, according to a video posted on the Chinese video-sharing site Bilibili, a user has managed to get MFG working on an RTX 4080 Laptop GPU. This is running on a Linux system – the ‘crack’ to get this whole setup working hasn’t been figured out on Windows yet, reportedly the card would only render a black screen on the Microsoft OS.

The video shows a console window with specs displaying proof of the RTX 4080 in operation. Then, tabbing back into Cyberpunk 2077 settings, we can see that DLSS Frame Generation is toggled on with a 4X multiplayer – the maximum value supported by DLSS 4 MFG. Performance stats show a rock-steady capped 120 FPS, though it isn’t immediately clear how much difference the frame generation is making.

We don’t expect Multi Frame Gen to come to the 40 series any time soon

When Nvidia announced its new 50 series, it gave us some insight into the upgraded hardware that enables support for AI technology such as Multi Frame Generation. Nvidia says that the new Blackwell architecture is built with “enhanced hardware flip metering capabilities” designed to support the frame pacing requirements of MFG. Without this hardware-level improvement, you may have to deal with VRR flickering and stuttering when trying to use MFG on 40 series (or below) hardware.

With that in mind, we don’t expect Nvidia to simply flip a switch to make it happen. On top of that, MFG is one of the biggest selling points of the newest generation of cards, with DLSS 4 heavily featured in Team Green’s first-party benchmarks. There’s still no support for DLSS frame generation on the RTX 30 series. It hasn’t been ruled out yet, but don’t get your hopes up.
