Nvidia launches DLSS 4.5 with 6x Frame Generation, better image quality on RTX 40‑ and 50‑series
Nvidia’s latest software update promises a noticeable bump in visual fidelity for gamers who have already upgraded to the company’s newest graphics cards. The rollout, announced alongside a 6× Frame Generation boost, targets the RTX 40‑ and 50‑series, the hardware line that currently powers high‑end PC rigs and next‑gen consoles. While the feature set is being pushed to every RTX GPU on the market, the performance ceiling is clearly set by the newest silicon, where the added transformer model can work with more bandwidth and compute headroom.
Early testers have noted that previous iterations sometimes left ghosting or shimmering around fast‑moving objects; the new version aims to smooth those rough edges. Nvidia’s engineering team frames this as a “second‑generation model,” implying a step beyond the earlier release. The company says the changes should translate into cleaner textures and fewer visual glitches across a broader range of titles.
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
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.
Will the promised gains hold up in everyday use? Nvidia’s DL SSL 4.5 arrives with a second‑generation transformer model that claims better overall image quality and fewer artifacts than its predecessor. The update also introduces a 6× Multi‑Frame Generation mode, capable of creating up to five extra frames for each rendered one, but only on the new RTX 50‑series silicon.
On RTX 40‑series cards the feature runs at its highest speed, while older RTX GPUs receive the same model with reduced performance. All RTX owners can download the update today, so the rollout is immediate. Yet the real‑world impact remains unclear; developers have not disclosed how many titles will support the new mode, nor how noticeable the frame‑generation boost will be in practice.
The announcement offers no benchmark data, leaving reviewers to verify the claims. In short, Nvidia has delivered a software upgrade that could tighten image fidelity and expand frame‑generation capabilities, but whether it will translate into a perceptible experience for most users is still uncertain.

Common Questions Answered
What improvements does the new transformer model in DLSS 4.5 bring compared to the previous version?
The second‑generation transformer model in DLSS 4.5 uses roughly five times more compute power than the original, delivering noticeably better overall image quality and reducing the artifacting that was common in DLSS 4. These enhancements are most evident on the RTX 40‑ and 50‑series GPUs.
Which Nvidia graphics cards can fully utilize the 6× Multi‑Frame Generation mode introduced with DLSS 4.5?
The 6× Multi‑Frame Generation mode, capable of creating up to five extra frames per rendered frame, is supported exclusively on the new RTX 50‑series silicon. RTX 40‑series cards run the feature at their highest speed, but they do not receive the full 6× boost.
Will older RTX GPUs receive the DLSS 4.5 update, and if so, how does their performance differ?
Yes, DLSS 4.5 is available for all RTX GPUs, but older models get the same transformer model with reduced performance. They will see some image‑quality gains, yet they cannot achieve the same speed or the 6× Multi‑Frame Generation benefits as the RTX 40‑ and 50‑series cards.
How does DLSS 4.5’s image quality on RTX 40‑series cards compare to its performance on RTX 50‑series cards?
On RTX 40‑series GPUs, DLSS 4.5 runs at its highest speed for that generation, offering improved image fidelity and fewer artifacts than previous DLSS versions. However, the RTX 50‑series cards combine this image quality with the additional 6× Multi‑Frame Generation boost, delivering the most advanced visual experience.
