You are grasping at straws here. The high textures are the same, and they take the same amount of memory on the same settings.
The difference for High textures is the tunable setting for "Texture Streaming Rate". When the game was released this wasn't tunable, and the rate seemed to be locked at what is now called the "Fastest" setting which made it stutter on an 8GB card, but the new "Fast" setting seems to be tuned very well for 8GB GPUs, enabling high textures without stutter or pop in. The new "Normal" setting seems to be the new default, which causes pop-in.
Not grasping any straws. The video shows various texture settings and their vram usage but does not say what resolution that is at. It also states a texture setting without specifying if it is environmental textures or one of the other settings, the assumption would be that high means all of those sub settings are set to high but without it being explicitly stated there is room for ambiguity which does not need to be there.
PS5 runs the game at 1440p High at around 70-80 FPS unlocked or it can run at 4k High at around 30 - 45 fps. That is around RX 6800 tier performance and the 3070/3070Ti simply falls away at those same settings and the same will happen to the 4060Ti 8GB and 4060. In this case the PS4 GPU is punching above its weight because in raw specs it is a 6700 with a bit more VRAM.
For as good as many people claim DF is, and they are for pixel peeping and console comparisons, when it comes to PC they seem to make a lot of rudimentary mistakes when presenting information.
