GoKawiilNvidia's October DLSS 5 update doubles speed, cuts 4K VRAM use by 20%
Nvidia announced an October update to DLSS 5 that doubles performance versus the current model, a 10x gain since March. The update shrinks the model to 118 million parameters, cuts 4K VRAM usage by 20%, and halves GPU overhead at similar image quality, boosting frame rates by up to 1.4x. The faster model debuts in NBA 2K27 on October 16, with Hogwarts Legacy support coming next month, alongside a new faster Performance Mode for Frame Generation on RTX 40 and 50 series GPUs.
GoKawiil's interpretation of the reporting above, not reported fact.
Smaller, faster neural models mean DLSS's AI rendering overhead eats into less of a GPU's actual performance budget, which could make upscaling and frame generation more viable on lower-end cards like the RTX 5060. The rapid iteration pace—10x gains since March—suggests Nvidia is treating DLSS as a continuously evolving software product rather than a fixed feature tied to hardware generations.
- DLSS 5's October update is 2x faster than the prior model and 10x faster than March's version.
- Model size dropped to 118 million parameters, cutting 4K VRAM use by 20% and halving GPU overhead.
- NBA 2K27 gets the update October 16, with Hogwarts Legacy and a new Frame Generation Performance Mode following.
NVIDIA GeForce RTX 5080 Graphics Card — If you want to actually experience DLSS 5's neural rendering gains firsthand, you need an RTX GPU with the latest Tensor cores to drive it. The RTX 5080 offers plenty of VRAM headroom and horsepower for 4K gaming, letting you take full advantage of these efficiency improvements. It's a great match for upcoming DLSS 5-enabled titles like NBA 2K27.
