Although DLSS 4.5 was first launched at this year’s CES in January, Nvidia RTX GPU owners have so far only enjoyed an upgraded Super Resolution model. Today, on March 31, Nvidia has upgraded DLSS 4.5 to introduce the remaining announced features, namely Dynamic Multi Frame generation with up to 6x support. This translates to a total of five AI-generated frames on top of the natively rendered one, and DLSS 4.5 dynamically adjusts how much frame gen you need for an optimal, smooth experience.

Nvidia has already provided a bunch of examples to demonstrate the capabilities of the new MFG 6x mode, showing its potential for “unlocking 240Hz 4K gaming with real-time path tracing”. In less demanding scenes, Dynamic MFG cuts down the number of AI-generated frames, seamlessly, providing you with suitable performance without ever overdoing it.

DLSS 4.5 with Multi Frame Gen 6x latency tests

Korean publication Quasar Zone has already tested latency while using DLSS 4.5 Multi Frame Generation, up to 6x mode. The test is being run in Cyberpunk 2077 at 4K with RT Overdrive, with DLSS 4 upscaling and Nvidia Reflex enabled.

As you’d expect, the more AI-generated frames in the mix, the more latency builds up. This is another aspect of Dynamic Multi Frame Generation that comes in clutch, ensuring you can enjoy smooth and responsive gameplay as much as possible, as the multiplier is automatically lowered where suitable.

From top to bottom (green to light gray), the benchmarks below show latency values for 6x, 4x, 2x, and zero frame generation modes. The latency difference between 4x and 6x modes is just a couple of milliseconds in most cases, all the while boosting average framerates dramatically.

Again, from top to bottom, the benchmarks cover DLSS Ultra Performance, Performance, Balance, and Quality modes. The highest latencies are found in Quality mode – up to 67.1ms, while dropping down to Ultra Performance nets you latency as low as 37.4ms, even with a 6x multiplier. It works out as nearly 260% higher framerates for around 56% extra latency difference.

Nvidia Reflex is also being used to help cut down these values – we recently tested Nvidia Reflex in Battlefield 6 with exceptional results. We’re still waiting for Reflex 2, however, which promises to cut down the latency values even more. We haven’t heard Nvidia talk about the second-gen version since around this time last year.

DLSS 4.5 Dynamic Multi Frame Generation can be activated and configured globally, or on a per game basis in the NVIDIA app’s Graphics tab.

Open “DLSS Override – Frame Generation Mode”, select “Dynamic”, and choose “Max refresh rate” for the NVIDIA app to synchronize your maximum frame rate with the maximum refresh rate of your display, for optimum motion clarity. Alternatively, pick “Custom” and type in a maximum frame rate for DLSS 4.5 Dynamic Multi Frame Generation to target.

Although all RTX GPUs benefit from the upgraded Super Resolution model in DLSS 4.5, Multi Frame Generation and Dynamic Multi Frame Generation remain exclusive to Nvidia’s latest RTX 50 series graphics cards.
