Nvidia says my RTX 4070 Super isn't capable of Multi Frame Gen, but I'm surprised by how smooth this unofficial unlock actually feels
Whatever it takes to stave off that pricey upgrade for a few more years.

Multi Frame Generation (or MFG) smoothes out gameplay by using AI to create as many as five generated, or 'fake' frames for each one actually rendered by the GPU. Nvidia first introduced the original 2x Frame Generation feature with the RTX 40-series graphics cards back in 2022, but the highest rates of frame gen are reserved for the RTX 50-series.
If you have an RTX 5090 (despite it being particularly tricky to find one, let alone for a price anywhere near MSRP), you can enjoy as much as 6x MFG in supported games. This is because the RTX 50-series GPUs contain more powerful Tensor cores, but also a dedicated AI Management Processor (AMP) which works alongside Flip Metering to deliver frames, both rendered and AI-generated, to your display as smoothly as possible. Older cards, like my RTX 4070 Super, lack this snazzy silicon—but us PC gamers won't let something as silly as official limitations stop us.
I've already detailed how you can get 4x Multi Frame Generation working on an RTX 40-series GPU using some simple mods. I'll tell you what I found across all of my testing shortly, but first let me speedrun through how I got this working in the first place. Very simply, I used the ReShade HDR Installer to download unofficial mods that unlock higher rates of Multi Frame Generation for RTX 40-series cards. My RTX 4070 Super officially supports up to 2x MFG, but the unofficial mods mean I can test up to 6x MFG with this same card.
As Nvidia does not officially support more than 2x MFG on RTX 40-series cards, I was fully expecting some quirkiness ahead.
Even on an RTX 50-series card, officially supported Multi Frame Generation can introduce blurry frames and latency issues, so I'm not really expecting my RTX 4070 Super to fare better on those fronts. My testing is more about getting as much as I possibly can out of the hardware I already own, and silencing the voice that says I need to drop silly money on an RTX 50-series card at least for a little while longer.
Now, not all games support even the standard 2x MFG. So, let me tell you I was surprised to discover that story-heavy games like Lost Records: Bloom & Rage and The Thaumaturge both support up to 6x MFG (you can check Nvidia's full list of games that support MFG here). As such, the full roster of games I tested is a little non-traditional. It's worth noting too that I am only testing single-player games as the MFG unlock mods I'm using are not officially supported and can trigger in-game anti-cheat detection systems. Sorry, Arc Raiders, I don't want to get banned.
As for settings, I tested all games at 1440p resolution, and used High graphical settings. I also set the Nvidia DLSS quality mode to 'Balanced', and turned off ray tracing and similar tech where applicable. I set ReShade HDR Installer to tap out at 4x MFG as not all games support all the way up to 6x. My thinking was that more PC gamers might be interested in testing 4x MFG on an RTX 40-series card for that reason. I set no target frame rate beyond that, though, in the hopes that this experiment would give me the fullest picture of the highest highs and lowest lows in terms of frame rate.
