Yeah I am going to need some proof of your claim.
A regular 2060 with RTX DLSS on:
BFV it performs almsot even.
Metro it wins by a comfortable margin (The best use of RTX/DLSS).
Tomb Raider it's even.
The 2060 Super has 2070 performance so it will perform between 10-20% better than what you see in the videos RTX/DLSS on.
Metro's use of RTX/DLSS will be the standard moving forward, creating a vast performance gap from the last gen in many upcoming games.
The 3080 series will make this gap even wider over the 2080 series.
