But the high textures aren’t usually “potato” like you make it seem. They look decent enough. When in motion, you are not going to see a big difference when everything is moving past you.
See Watch Dogs Legion for instance. The only tangible difference which is visible is between Low and Medium. Move to High and the difference is less obvious and ultra needs pixel peeping to tell any differences.

There are always the odd exceptions here and there like Far Cry 6, whose stock textures are complete crap but in games like CP2077, Metro Exodus, I could not tell much of a difference.
