Nvidia is pushing its DLSS technology forward again, and this time the big headline is smoother, higher-frame-rate gameplay with fewer of the drawbacks that made earlier frame generation controversial.
When the Ada generation arrived, Nvidia introduced frame generation using the GPU’s optical flow accelerator. It was a major leap for perceived smoothness, because the system could create additional frames rather than relying only on traditionally rendered ones. With the newer RTX 50-series Blackwell GPUs, that concept evolved into Multi Frame Generation (MFG), which could boost performance up to 4x the base frame rate thanks to a Blackwell feature known as hardware flip metering.
That extra fluidity came with trade-offs, though. Many players worried about increased latency and input lag, especially in competitive or twitchy games. Nvidia Reflex can reduce a large portion of that delay, but concerns didn’t stop there. Another frequent complaint was visual artifacts, which could stand out more in fast-paced scenes where rapid motion and complex effects make frame synthesis harder.
Now Nvidia says DLSS 4.5 addresses those issues while extending MFG even further. With a second-generation Transformer model working alongside Multi Frame Generation, RTX 50 Blackwell GPUs can now reach up to 6x MFG. Nvidia’s pitch is that this isn’t just about inflating frame counts—it’s about improving frame pacing and image quality so the experience feels more natural, with the explicit goal of reaching 240 frames per second in demanding scenarios. That target also makes sense in today’s market, where 240 Hz gaming monitors are becoming far more common than they used to be.
One of the most practical additions in DLSS 4.5 is Dynamic Multi Frame Generation. Instead of forcing users to pick a fixed multiplier and live with the consequences, the system can automatically choose the right MFG level on the fly, scaling up as needed to match your monitor’s refresh rate, up to the 6x maximum. In theory, that should help keep gameplay looking consistent while avoiding unnecessary overhead when you don’t need the extra generated frames.
Nvidia is also sharing an attention-grabbing performance claim to show what DLSS 4.5 plus 6x MFG can do on high-end hardware. According to the company, an RTX 5080 can hit up to 246 fps at 4K in Black Myth: Wukong with path tracing enabled—exactly the kind of punishing workload that normally makes ultra-high frame rates seem out of reach.
For gamers chasing high-refresh 4K performance, especially with ray tracing or path tracing turned on, DLSS 4.5 and Multi Frame Generation up to 6x could be one of the most important RTX 50-series upgrades yet. The real test will be how well Nvidia limits latency and cleans up fast-motion artifacts across a wide range of games, but on paper, the focus on better pacing, adaptive scaling, and higher quality frame generation is clearly aimed at turning “big fps numbers” into a smoother experience you can actually feel.
