NVIDIA's Turing GPUs have been on the market for almost a year now. The architecture introduced real-time ray tracing support as well as Deep Learning Super Sampling (DLSS), a technique that promises higher image quality at a lower performance cost. Both technologies haven't really seen major uptake but NVIDIA is still pushing them hard. In a new blog post, NVIDIA shows how DLSS works in the new Control video game, you can check it out over here.
Let’s look at an example video, below. The left side uses Control’s in-engine scaling. The right side shows DLSS. Both sides are rendering at 720p, and outputting at 1080p. Notice how DLSS brings out more detail and improves temporal stability, reducing flickering and shimmering.
But even NVIDIA admits DLSS isn't perfect:
While the image processing algorithm is a good solution for Control, the approximation falls short in handling certain types of motion. Let’s look at an example of native 1080p vs. 1080p DLSS in Control. Notice how the flames on the right are not as well defined as in native resolution.
Clearly, there’s opportunity for further advancement.
