Nvidia says DLSS 5 just got twice as fast, and lighter, than the model it shipped last month.
The October update halves GPU overhead at matching visual quality, trims the model's parameter count by nearly a quarter to about 118 million, and cuts 4K VRAM usage by 20%. Nvidia credits "pipeline optimizations and neural model refinements" for the gains, which it says add up to a 10x performance improvement since DLSS 5's March debut. The company is also shipping a faster Performance Mode for Frame Generation on RTX 50 and 40 series cards and RTX Spark laptops, plus a new "Preset C" mode that swaps an AI model used for optical flow calculations with a lighter algorithm, good for a 35% speed bump on an RTX 5060. NBA 2K27 gets the new model first on October 16, with Hogwarts Legacy following next month.
The VRAM cut matters more than the speed bump. DLSS has always asked players to trade performance overhead for its upscaling and frame generation tricks; a 20% smaller footprint at 4K is relevant on 8GB and 12GB cards, where VRAM, not raw compute, is often the bottleneck. It also raises the bar for AMD's FSR to show similar efficiency gains, not just bigger upscaling claims.
Still, a model that improves 10x in seven months says as much about how unoptimized the original release was as it does about Nvidia's engineering. Free performance is nice. It is also a reminder that "done" software often ships with a lot of slack left on the table.
