Nvidia is announcing its next major update to its Deep Learning Super Sampling (DLSS) feature at CES today. DLSS 4.5 includes Nvidia’s second-generation Super Resolution transformer model and a new 6x Multi Frame Generation mode for RTX 50-series GPUs that uses AI to generate up to five additional frames for every single rendered one.
DLSS 4.5 will be available for all RTX GPUs today, but will run the fastest on Nvidia’s latest RTX 40- and 50-series cards. The latest transformer model is designed to improve image quality overall and reduce some of the artifacting that we saw with DLSS 4.
“This second-generation model is our most sophisticated yet,” says Henry Lin, director of product management at Nvidia, in a briefing with The Verge. “It utilizes 5x the compute power over the original transformer model, it’s trained on a significantly expanded high-fidelity dataset, and it also takes full advantage of our GeForce RTX 40- and 50-series GPUs, which benefit from faster and more advanced Tensor Cores.”
Nvidia has updated its DLSS model to better understand scenes in games so it can use game engine data to improve lighting, finer edges, and motion clarity. In a briefing, Nvidia demonstrated improvements to DLSS 4.5 in a variety of games. Ghosting is reduced in The Elder Scrolls IV: Oblivion Remastered, anti-aliasing is improved in Indiana Jones and the Great Circle, and there is less shimmering in certain scenes in Kingdom Come: Deliverance II.
While the AI model improvements to DLSS 4.5 will benefit all RTX owners today, Nvidia is also launching a new 6x Multi Frame Generation mode for RTX 50-series owners in spring. Targeted at 240Hz 4K gaming, the 6x mode will generate five additional fake frames for every single rendered one, instead of the maximum of three additional in DLSS 4.
Nvidia is also launching a Dynamic Multi Frame Generation mode that automatically switches between different Multi Frame Generation levels depending on when you need more or less fake frames. “When things are really graphically intense, it upshifts and increases the Frame Generation required to bridge the performance dips, ensuring that your high refresh rate monitor remains buttery smooth,” explains Lin. “When the workload lightens, it seamlessly shifts the multiplier down to compute only what’s needed.”
DLSS 4.5 will be available for more than 400 games and apps through Nvidia’s app today, allowing RTX owners to force 4.5 on in games that haven’t been updated yet. Nvidia is only committing to a vague “spring 2026” timeframe for its 6x Multi Frame Generation and Dynamic Frame Generation modes for RTX 50-series owners.
