Coming from bg3, I had the opposite opinion. BG3 loading screens take a while but it doesnt load very much unless your loading saves a lot. With Starfield you get hit with a small loading screen constantly like when transitioning in/out of ships, buildings, planets, etc.
For me it's not the speed, but the quantity. Docking? Loading screen. Launching off planet? Loading screen. Changing planet? Loading screen. Landing on the same planet? Loading screen. The only solution is to fast travel everywhere in an "immersive" space sim RPG. NMS and Elite:Dangerous have solved this issue. Bethesda needs to get with the times already.
