Maybe the graphics are that intense, even at whatever they chose to call “medium”. Try “low” then and see how those work out.
You are worked up about linguistics because it’s nothing more to you at the moment. Just because you’re used to run every other game at “high” or whatever, doesn’t mean this different game has to be the same.
I refuse to agree with “my midrange GPU has to be able to run everything at Ultra for #random number# of years or I am going ballistics”. I want progress. That’s what I buy new hardware for every few years. If you want graphics to be stuck and don’t advance in any meaningful way, get a console.
