Summary

  • DLSS 4.5 has added Dynamic Multi Frame Generation and 6X Multi Frame Generation to its RTX 50-series GPUs.
  • Nvidia touts up to 4K/240Hz and 1080/1440p up to 360Hz, smoother high-resolution/high-refresh gaming.
  • AI frame gen can produce artifacts (hair, rain, lighting), but it improves smoothness in supported games.

Following the release of DLSS 4.5 Super Resolution earlier this year, Nvidia has dropped an update for DLSS 4.5 that boosts the frame rate of RTX 50 series GPUs, Dynamic Multi Frame Generation and Multi Frame Generation 6X. The feature was first announced back at CES 2026.

With these new DLSS 4.5 features turned on, Nvidia says it's offering the "smoothest path-traced gaming yet," allowing 4K gaming at 240Hz and 1080p/1440p at 360Hz. Instead of multiplying the frame rate by a fixed amount, DLSS 4.5 Dynamic Multi Frame Generation dynamically adjusts to balance refresh rate, responsiveness, and image quality. It also doesn't push the frame rate above your monitor's refresh rate and is more power-conscious, so your 4K 144Hz monitor won't push to 160Hz and waste headroom.

On the other hand, Multi Frame Generation 6X, which is based on Nvidia's second-generation transformer model, boosts the maximum multiplier to 6X, generating up to five extra frames per rendered frame. Nvidia says this feature can boost 4K frame rates by up to 35 percent.

For better or worse, rasterization continues to be buried, and it won't be long until games are unrecognizable

These features aim to make gaming at higher resolutions and refresh rates a smoother experience

Like DLSS 4.5 Super Resolution, Dynamic Multi Frame Generation and Multi Frame Generation 6X can result in weird graphical glitches

Both features are powered by AI, which can sometimes result in weird artifacts with some in-game details, like hair, rain, and lighting/shadows. Still, if you're looking to play games at a high resolution and refresh rate, Dynamic Multi Frame Generation and Multi Frame Generation 6X should offer smoother performance. Several titles already support the features, including 007 First Light (May 27th), Control Resonant, Directive 8020 (May 12th), and Tides of Annihilation. It's important to note that both Multi Frame Generation and Multi Frame Generation only work on Nvidia's RTX 50-series GPUs.

I play most games at 4K with maximum settings, between 120Hz and 144Hz, on my RTX 5090-equipped gaming PC. Since my monitor's refresh rate is capped at 144Hz, it's unlikely I'd take advantage of this update. That said, if I end up buying a new monitor (I've been thinking about it for a few months now), then I'd definitely give Dynamic Multi Frame Generation and Multi Frame Generation 6X a try.
