Nvidia's October DLSS 5 model runs much faster, but image-quality issues remain
Nvidia has released a new October version of its DLSS 5 neural rendering model, saying the update cuts the model's parameters by 24%, halves execution time and reduces VRAM usage by 20% while keeping image quality broadly comparable. TechSpot tested it in NBA 2K27, again the first game to officially ship with the latest model, and measured average render-time gains of about 83% at 4K and 94% at 1440p across the RTX 50 lineup — substantial but short of Nvidia's claim of running twice as fast, with TechSpot noting the speedup applies to DLSS 5's own rendering cost rather than overall frame rates. TechSpot said performance, not visual quality, was the focus of this release, and that artifacts and image-quality issues from the original launch remain.
TechSpot concludes the optimization makes neural rendering viable on more GPUs than at launch, but says doubling processing speed addresses only one of several problems the technology still needs to fix.

Nvidia has released a new version of DLSS 5 neural rendering, claiming it runs twice as fast as the previous model. This October update reduces the number of parameters in the DLSS 5 model by 24%, halving execution time and reducing VRAM usage by 20%. All of this has been achieved while maintaining comparable image quality, according to Nvidia.
We thought it was worth revisiting DLSS 5 in everyone's favorite title, NBA 2K27, which is once again the first game to officially ship with the latest model. Does the new version really run twice as fast across all RTX 50 series GPUs without compromising image quality? Does it address some of the issues we raised in our initial DLSS 5 analysis? And does this performance improvement make DLSS 5 worth using now?
