It’s been a heck of a time lately for PC gamers willing to get their hands dirty with mods. Hot on the heels of the discovery of the DLSS 5 DLL in a prerelease version of NBA 2K27, modder dashdogy found a way to bring Multi Frame Generation, one of the crown jewels of GeForce RTX 50-series graphics cards, to RTX 40-series (and earlier) products.As already elevated graphics card prices seem set to continue rising, and hardware upgrades get further and further out of reach of the average PC gamer, more and more folks are going to want to hold on to the RTX 40-series hardware they have for as long as they can, especially if smoothness-boosting features like MFG are just a few clicks away on those older cards.So we had to see MFG working on Ada for ourselves—assuming it works at all. We grabbed the mod files and got to playing with them in Cyberpunk 2077, since it’s likely in many TH readers’ Steam libraries already and has a healthy modding community. You can find the latest instructions for enabling MFG on Ada through dashdogy’s GitHub page.Before spending a ton of time testing, we verified that the mod works at all. While spinning the camera at a high, constant speed, we could indeed see that increasing MFG multipliers beyond the officially supported 2X factor on Ada cards does greatly increase perceived smoothness or fluidity of motion in Cyberpunk 2077, as you would expect.Another tell is that the same visual artifacts are visible in certain regions of the screen on both RTX 40-series and RTX 50-series graphics cards as you add more generated frames. MFG 4X and above, especially, tend to add some visual “junk” at the bottom of the frame that appears regardless of the game, and we could see that artifacting on Ada.At least in Cyberpunk 2077, then, we’re confident that MFG is really doing its thing on RTX 40-series cards with this mod.We also didn’t see any perceptible issues with frame pacing or frame delivery, although playing on a high-refresh-rate, G-Sync-Compatible monitor like our test bench’s ROG Strix XG27UCS smooths out all but the worst such issues. If you don’t have a high-resolution or high-refresh-rate monitor to begin with, the utility of MFG will be seriously limited for you anyway.Get Tom's Hardware's best news and in-depth reviews, straight to your inbox.The latency questionSo is this a free lunch? Is Nvidia soft-locking MFG to Blackwell purely for marketing reasons? That’s where performance testing comes in, since it has the potential to reveal whether there’s a catch in running MFG on Ada. The question is not so much whether MFG juices output frame rates, but whether it runs on Ada within acceptable latency thresholds.As we’ve long emphasized, when you have essentially arbitrary control over output frame rates like MFG allows, input lag becomes the final barrier to a playable experience. So in the performance results that follow, we’ll certainly present output frame rates as you would expect. But you should view those in the context of your own monitor’s refresh rate. As long as the delivered frame rates we recorded exceed your display’s peak refresh rate, you have headroom to play with to keep your monitor at or near that number during gameplay.The real issue, then, is whether both RTX 40-series and 50-series cards deliver an acceptable input latency under our test conditions. In our past testing, we’ve determined that a roughly 60ms average latency threshold, as indicated by Nvidia’s FrameView app, is the point at which player inputs and displayed frames start to become noticeably decoupled in AAA single-player experiences like Cyberpunk. If you’re only slightly on the wrong side of this threshold, a game might still be playable, but if you totally blow past it, you’re likely to notice laggy inputs and increasingly distracting visual artifacts as the MFG model struggles to fill in the gaps between sparser and sparser input data.Testing methods and notesAs one of the biggest technical showcases of the current PC gaming era, Cyberpunk 2077 lets us enable all the modern rendering features we’d want for Nvidia cards. It implements not only ray tracing and path tracing, but DLSS Super Resolution, Ray Reconstruction, and Multi Frame Generation. The number of AI-generated pixels per frame can be quite high in this title.We enabled all those features to expose the full potential complexity of running all of their associated AI models in a modern rendering pipeline. If RTX 40-series cards are going to stumble for some reason with modded MFG enabled, we want to put as many obstacles in their way as possible.And because benchmarking the performance of an unofficial mod is venturing into the Wild West anyway, we also added a DLSS 5 mod to the mix to see whether Blackwell GPUs have a distinct edge in the neural rendering future that the arrival of that feature promises to usher in. DLSS 5 is supposed to come to RTX 40-series cards later this year, so we think it’s good to understand where performance sits today, even if it’s subject to the same disclaimers as this MFG mod.For reference, then, we tested Cyberpunk with maxed-out raster settings, path tracing, and MFG 4X at three resolutions: 1080p with DLSS Balanced, 2560x1440 with DLSS Performance, and 4K with DLSS Ultra Performance upscaling enabled.We only tested cards ranging from the RTX 4090 down to the RTX 4070 for these experiments, both because of time and Cyberpunk’s VRAM requirements. We didn’t want to deal with potential performance pitfalls due to running out of VRAM, so the 12GB RTX 4070 is where we’re drawing the line for now.Modded Cyberpunk 2077 1080p performance
