NVIDIA DLSS Deep Learning Ultrasampling Anti-Aliasing Technology is an intelligent anti-aliasing technology based on artificial intelligence, neural network, machine learning, which not only brings sharper picture, but also greatly improves frame rate, fish and bear palm can also get both. DLSS 1.0 was born with the RTX 20 series and later upgraded to DLSS 2.0, and now with the release of the RTX 30 series, NVIDIA has quietly upgraded to DLSS 2.1.
As with version numbers, DLSS 2.1 doesn’t change much, mainly by supporting 8K resolution and VR-compatible virtual reality games, as well as dynamic resolution.
VR games generally require resolutions of no less than 2880 x 1600, the refresh rate is stable at least 90Hz, and some head features such as Valve Index require a maximum of 144Hz.
If the game wants to get high frame rate at high resolution, the graphics card requirements are naturally very demanding, now with rtX 30 series, coupled with DLSS assistance, this is not a thing, can let the game at half the resolution of rendering, and then intelligently zoom in to high resolution, while still having a high enough frame rate.
NVIDIA also gave a set of data, RTX 3080 graphics card at 4K resolution, DLSS on the game performance can be improved by about 80%, many up to 1.7 times.
