Nvidia 调低 DLSS 5 默认强度，11 月 5 日随 Hogwarts Legacy 上线
DLSS 5 gets toned down for its Hogwarts Legacy debut next month
- 1Nvidia 为 11 月 5 日登陆 Hogwarts Legacy 的 DLSS 5 调低生成强度，面部与环境改动比年初演示明显收敛
- 2Nvidia 维持开发者拥有细致艺术控制权的口径，DLSS 5 如何接入由游戏厂商自行决定
- 3官方称 10 月更新使 DLSS 5 体积缩小 24% 至约 1.18 亿参数，4K 显存占用降 20%，RTX 50 系列速度翻倍
- 4Nvidia app 测试版为 RTX 40/50 系列新增 Frame Generation 性能模式，官方称最高提速 35%，画质有轻微取舍
Nvidia 把 DLSS 5 的默认生成强度调低，把画面控制权明确留给游戏厂商，回应年初玩家对改脸效果的反弹。
- 影响：AI 生成内容改动素材原貌会引发用户反弹，默认档位和人工控制权需要写进产品规则；模型体积与显存占用同步下降，同类生成功能对硬件门槛和运行成本的要求在降低。
- 参考：可考虑在自家 AI 生成功能里预留强度档位，让业务方审批默认效果后再上线；值得把更小参数量、更低显存的新模型纳入终端部署成本测算。
- 依据：效果对比截图与参数、显存、提速数字均为 Nvidia 官方口径，暂无独立验证；作者对面部变化的描述属个人观察。

When Nvidia originally showed off DLSS 5 earlier this year, the technology immediately got branded as gen AI for video games. To gamers, Nvidia had lost the plot. I personally couldn’t get over how faces were transformed using DLSS 5. The 15-year-old student from Hogwarts Legacy suddenly looked much older, and Grace from Resident Evil Requiem looked yassified.
Now more than six months later, DLSS 5 is about to debut properly in Hogwarts Legacy, and it looks like it has been seriously toned down. Nvidia published new comparison screenshots today, where the changes to faces are as subtle as they are in NBA 2K27. Teenagers no longer look like middle-aged men, and even the environmental changes look more subtle.
Nvidia has always maintained that developers have “detailed artistic control” over DLSS 5, and ultimately make the choice on how to implement the technology in their own games. DLSS 5 will now appear in Hogwarts Legacy on November 5th, and it’s also coming to Where Winds Meet late next month.
Nvidia is also improving the performance hit of DLSS 5 with an October update to the neural rendering system that should make it twice as fast on RTX 50-series GPUs and the upcoming RTX Spark laptops. “The DLSS 5 October update shrinks the footprint by 24 percent to roughly 118 million parameters while reducing 4K VRAM usage by 20 percent,” says Nvidia’s Andrew Burnes. This new DLSS 5 model will debut first in NBA 2K27 on October 16th and “will ship by default with future DLSS 5 games.”
Alongside the DLSS 5 updates, Nvidia has also shipped a new Nvidia app beta update that includes a faster performance mode for Frame Generation on RTX 40- and 50-series GPUs. The updated AI model uses a “faster and lighter algorithm to boost frame rates” for Frame Gen, Multi Frame Gen, and Dynamic Multi Frame Gen. Nvidia says it has “minor trade-offs in image quality,” and that performance mode for Frame Generation should now be up to 35 precent faster.
