In April 2020, Nvidia advertised and shipped with driver version 445.75 an improved version of DLSS named DLSS 2.0, which was available for a few existing games including Control and Wolfenstein: Youngblood, and would be available later for upcoming games. This time Nvidia said that it used the Tensor Cores again, and that the AI did not need to be trained specifically on each game.[2][8]
A side effect of DLSS 2.0 is that it seems not to work very well with anti-aliasing techniques such as MSAA or TSAA, the performance being very negatively impacted if these techniques are enabled on top of DLSS.[9]
As of April 2020, DLSS 2.0 must still be included on a per-game basis by the game developers.
DLSS 1.0 February 2019 First version, using AI and specifically trained for some specific games, including Battlefield V and Metro Exodus
DLSS 2.0 (first iteration) August 2019 First 2.0 version, also referenced as version 1.9, using an approximated AI of the in-progress version 2.0 running on the CUDA shader cores and specifically adapted for Control
DLSS 2.0 (second iteration) April 2020 Second 2.0 version, using Tensor Cores again and trained generically
