Community tests confirm DLSS 4.5 yields 20%+ performance loss on older RTX 30 and 20 series GPUs compared to DLSS 4.0
Hogwarts Legacy and Cyberpunk 2077 also show a bit of ghosting or raggedness at the bottom edge of the screen in motion with MFG enabled, but it’s milder and easy enough to overlook since it’s well outside of the typical focus point for such games (i.e., the center of the screen).
Looking beyond those minor image quality concerns, the new combination of MFG multipliers up to 6X and the upscaling prowess of DLSS 4.5’s improved models opens up high-refresh-rate experiences at settings that would previously have been difficult to realize on lower-end graphics cards.
As an extreme example, MFG 6X and DLSS 4.5 Ultra Performance with Preset L makes Cyberpunk 2077 totally playable at a 240 FPS target on even the RTX 5070 with ultra settings and path tracing enabled, all with an input latency of about 52 ms.
We also measured PC latency with framegen off, at 2X, at 4X, and at a forced 6X to see whether the extra frames incur extra input latency, but in line with Nvidia’s claims, PC latency (as measured by the FrameView app) remained largely the same as with 4X.

However, performance scaling across the various modes didn’t track as cleanly with those multipliers as we would have expected. In another round of testing with our RTX 5080 in Cyberpunk 2077 , the average frame rates captured by FrameView with MFG active all fall short of the lofty figures you might expect from each multiplier.

As you can see from the figures above, despite our 60 FPS-ish baseline with DLSS Performance and a 4K target resolution, adding MFG to the picture didn’t result in the full boost you would expect, even with such a powerful graphics card in play. We’re investigating the reasons behind this shortfall and will update this article with further details as we’re able.
All that said, unlike dynamic resolution (or upscaling) modes that noticeably sacrifice image quality to maintain frame rates, Dynamic MFG mostly preserves the highest practical image quality from a given game and graphics card while transparently adjusting output frame rates as needed.
It’s the closest a dynamic performance mode has ever come to letting me stop worrying about output FPS entirely while gaming, and it’s another clear step into a future where output frame rate is just another setting to tweak instead of a hard limit of silicon.
If you’re already sold on what MFG has to offer, the combination of Dynamic MFG and its expanded multipliers makes framegen a set-and-forget experience instead of an exercise in constant adjustment. Enable Dynamic MFG globally and dial in your monitor’s peak refresh rate as your frame rate target in the Nvidia App, choose the in-game quality settings that produce a level of input latency you’re comfortable with, enable MFG in-game, and let Dynamic MFG take over.
That’s a fair amount of setup, but once it’s done, you’ll never have to worry about micromanaging your MFG multiplier to stay near the peak of your display’s refresh rate range ever again. It’s a great refinement of this tech, and we didn’t see any hitches or stutters as a result of multiplier shifts during gameplay.
The bigger question mark for many gamers is whether Nvidia can successfully generate even more frames from the same limited input data that MFG already ingests. As wild as stretching a single frame’s worth of input data into four or five generated frames may sound, MFG’s new 5X and 6X modes work well in our experience so far, and they work without introducing new or worse visual artifacts than we’ve already seen from past versions of the tech.
We also didn’t measure a large increase to input latency in exchange for the extra frames, which we’re glad for as Nvidia leans harder and harder on neural rendering techniques like MFG to enhance perceived performance.
If you haven’t tried MFG yet, and you already have a Blackwell GPU and a sufficiently high-refresh-rate monitor at your disposal, Dynamic MFG and its 5X and 6X modes are well worth a shot. You have nothing to lose, and if it’s not to your liking, you can turn it off again. If you still insist that every pixel of every frame be natively shaded at 4K, well, Nvidia has a graphics card for you, and it’s called the RTX 5090.
Joking aside, and as our past testing has already demonstrated , MFG still isn’t a performance panacea. It can only work off the baseline experience a given graphics card can offer, whether for better or for worse. It doesn’t let a weaker graphics card run more demanding settings than it otherwise could (which is still the domain of DLSS upscaling).
If you crank settings too high on too weak a GPU before adding framegen to the picture, your input latency will still rise beyond the baseline you need for a playable experience, and all the new MFG bells and whistles launching today don’t change that.
That leads us to another important point: If you’re still running a 1080p or 60Hz monitor (or worse, a 1080p and 60 Hz monitor) alongside any 12GB or 16GB Blackwell GPU that can capably run MFG, it’s time to consider an upgrade.
Especially with the advent of the DLSS 4.5 upscaling model and the fidelity it offers in its Performance and Ultra Performance presets, a high-refresh-rate 1440p or 4K monitor no longer requires a top-of-the-line graphics card to achieve a fluid and responsive experience with high image quality. Any 1080p monitor, however, puts a hard cap on upscaling image quality, and a 60 Hz monitor of any resolution puts a hard cap on fluid motion and (to a degree) responsiveness.
If you’re still running such a setup and have the means to upgrade to a higher-resolution, higher-refresh-rate display, there’s never been a better time amid spiraling costs for basics like RAM and SSDs. Monitors remain relatively insulated from the RAMpocalypse and NANDpocalypse, so if you’re pondering what your next upgrade should be, check out our list of the best gaming monitors for inspiration and put Dynamic MFG to work maxing out their refresh rates.

Notton You didn't test how much more RAM or GPU power MFG requires at each setting? Reply
PEnns "For GeForce gaming, 2026 has so far been the year of software updates to existing GPUs as the world's cutting-edge silicon gets swallowed up by AI demand" We are really happy our AI overlords will enjoy the new, fancy GPUs with DLSS 4.5 Dynamic Multi Frame Generation!! Reply

Notton CrazyCarrot911 said: Friends don't let friends play with faked frames ! God I hate this BS !!! Having used DLSS 4.5 with FG on with a 4070Ti, it's pretty good. DLSS 4 had issues with artifacts, but it's very challenging to notice in 4.5. It's a pretty good way to maintain a stable 120fps when the game has 1% lows of 60fps. Would I rather have a GPU that does 1% low of 120fps? Yes, but that's going to get really expensive really quick, and then I'd have to worry about it melting. Reply
saunupe1911 Technically why couldn't Nvidia enable this for the 4000 series? Reply

Call them what you like, but the DLSS + FG combo has the practical benefit of making gameplay smooth as butter. That's all i care about. Reply
txfeinbergs CrazyCarrot911 said: Friends don't let friends play with faked frames ! God I hate this BS !!! Funny thing is, I would have agreed with you 100% until very recently. I could only get 60 FPS out of Crimson Desert with everything set to Cinematic at 4K. Every attempt I have made in the past to use frame generation has been met with stuttering screen tearing crap as results. This is the first time where I am successfully using it at 2X and it made a somewhat rough experience completely smooth. So I guess it does have potential, but you already need to be able to get your performance up to at least 60 FPS with real frames. Reply

That's all i care about. ah but it doesn't in some instances it causes lag and artificing or some other ungodly nonsense. fake frames are not ok and are pointless and just a marketing gimmick which Jensen did try to pull lol. saying something 4k at 144 with dlss just tells me that at 2k i should reach 144. so just play native didn't they try to sell consumers that a 5070 was like a 4090 or some nonsense like that. basicly pay more for less is nvidias game including laughing to the bank Reply
