On this page, we're taking a closer look at performance with real-time raytracing enabled. The value in brackets is the performance difference of the same card, in the same test, with raytracing off.

NVIDIA DLSS is an image upscaling technology that uses machine learning to achieve best results. The 3D graphics are rendered at lower resolution, which improves performance, and then brought up to native resolution, with only minor loss in image quality.
