NVIDIA DLSS 5 获得 2x 性能提升且显存占用减少 20%

NVIDIA's continuous optimization of software and its technology stack has yielded another great improvement. The latest DLSS 5 update, scheduled for October 16, will deliver another 2x performance boost, meaning that previously DLSS 5-optimized workloads will literally run twice as fast. Alongside this significant performance uplift, NVIDIA promises that in 4K gameplay with DLSS 5 enabled, the neural rendering technology will use 20% less VRAM, leaving more room for game textures to load without DLSS 5 interfering with capacity or hogging resources. NVIDIA updates its DLSS by running a continuous loop on top of an internal supercomputer that constantly optimizes DLSS technology for performance, efficiency, and visual fidelity. Specifically for this week's DLSS 5 update, NVIDIA states that the company used a combination of systematic pipeline optimizations and neural model refinements to achieve that 2x performance boost.

Originally in late August, we saw that the leaked DLSS 5 file was roughly a 148 million parameter model. Our analysis turned out to be accurate, and we see that, according to NVIDIA, the DLSS 5 October update shrinks the footprint of this model by another 24% to roughly 118 million parameters, meaning that our original estimation was correct. Consequently, the smaller model scales memory usage almost linearly and cuts VRAM usage by about 20%. Compared to the initial launch in mid-March, when the DLSS 5 was showcased on two GeForce RTX 5090 GPUs, we see that NVIDIA managed to scale the performance by 10x in the span of a couple of months.
