Tech Focus: Nvidia DLDSR - What Does AI Downsampling Actually Do?

Downsampling or super-sampling down from a higher resolution is a brute-force form of anti-aliasing. Nvidia’s new DLDSR aims to do the same job with lower pixel counts, improved performance and maybe improved quality. What does it do? How does it work? Can a downsampled 1620p really look as good as a downsampled 2160p? And what happens if you combine DLSS with DLDSR? Alex Battaglia has answers!
