DLSS stands for "deep learning super sampling," and it’s a new rendering technology that only works with GeForce RTX graphics cards. There are two DLSS modes, but we can only test one of them right now, the standard DLSS mode, so it’s the only one we’ll be focusing on.

While the name does have “super sampling” in it, the standard DLSS mode isn’t really super sampling, it’s more of an image reconstruction technique that renders a game at a sub-native resolution, then uses AI inferencing to upscale and improve the image. And of course, the AI processing element of DLSS is only possible thanks to Turing’s tensor cores.

So what DLSS aims to provide is a 4K image equivalent to a native 4K presentation, except with higher performance than you’d otherwise get through native rendering. This is possible because at 4K, DLSS is actually rendering the game at approximately 1440p, so with 2x fewer samples, and then upscaling it using an AI network trained on a 64xSSAA reference imagery.

You could think of it as an advanced upscaling technology similar to checkerboard rendering or temporal rendering, techniques game consoles like the PS4 Pro use to run games at “4K” while actually rendering them at lower resolutions. Theoretically, DLSS fixes a lot of the issues with checkerboard rendering, making it more suitable for PC gaming where the artefacts generated through checkerboarding are much more noticeable.

DLSS代表“深度学习超级采样”，它是一种新的渲染技术，仅适用于GeForce RTX显卡。有两种DLSS模式，但我们现在只能测试其中一种模式，即标准DLSS模式，因此它是我们唯一关注的模式。

虽然名称确实有“超级采样”，但标准的DLSS模式并不是真正的超级采样，它更像是一种图像重建技术，可以让游戏处于亚原始分辨率，然后使用AI推理来升级和改进图片。当然，由于图灵的张量核心，DLSS的AI处理元素才有可能实现。

因此，DLSS旨在提供的4K图像相当于原生4K演示，除了具有比通过本机渲染获得的更高性能。这是可能的，因为在4K时，DLSS实际上渲染的游戏大约为1440p，所以样本减少了2倍，然后使用在64xSSAA参考图像上训练的AI网络对其进行升级。

您可以将其视为类似于棋盘渲染或时间渲染的高级升级技术，PS4 Pro等游戏控制台用于以“4K”运行游戏，同时实际以较低分辨率渲染游戏。从理论上讲，DLSS解决了棋盘格渲染的许多问题，使其更适合PC游戏，其中通过棋盘格产生的画质瑕疵更加引人注目。

看看PS4PRO的大表哥2插值画面

DLSS算是神了？我觉得下代主机最好有类似技术

DLSS支持的最低分辨率为1440P，这个分辨率是以1080p对游戏进行采样，然后进行升级

===============

不过看DLSS的消耗来说。和3K差不多(3200x1800)而它的画质不如4K。也差不多是在3K的水平线上

所以老黄吹的这个玩具其实也并没有多神？

光线追踪那才是实实在在的好啊。可那个消耗又是实实在在的大
