NVIDIA DLSS 5模型从《NBA 2K27》提取，Modders报告最高90%性能提升

NVIDIA shipped its faster DLSS 5 Neural Rendering model with NBA 2K27 on October 16, and it didn't take modders long to pull it out and test it elsewhere. Renan Maniero on X extracted the new 310.9.16.0 build of the DLL. That lets people inject it into games that don't officially support DLSS 5 through tools like RenoDX and OptiScaler. The new DLL also keeps the older model around as Preset A, with the new one sitting under Preset B, so comparing the two is as simple as switching presets. Gaming Optimized on X did exactly that, and found the new model running up to 90% faster than the old one in The Witcher 3. The channel points out that the gain varies from game to game, so 90% looks like the best case rather than the norm.

That roughly aligns with NVIDIA's own claims. The company says the October update shrinks the model by 24% to roughly 118 million parameters, cuts VRAM use at 4K by 20%, and runs the neural rendering workload up to 2x faster than the September version. NVIDIA also quoted up to 40% higher frame rates in NBA 2K27 specifically. Officially, DLSS 5 is still limited to RTX 50-series GPUs and GeForce NOW. NVIDIA plans to bring it to the RTX 40-series, though there's no date yet, and there's no word on RTX 30 or RTX 20 support. Modders, apparently, aren't waiting, since the OptiScaler README notes a modified runtime that gets it running on RTX 20-series cards as well.
