NVIDIA DLSS, the Deep Learning Super-Sampling technology powered by the Tensor Cores of the GeForce RTX GPUs, has improved a lot over time. It didn’t have the greatest start when it first landed, mostly due to the blurring introduced in the initial implementation.

That has improved since and the latest incarnation of DLSS, featured in Remedy’s Control, is certainly the best one yet as mentioned by Keith in his analysis.
