As the shadow distance is so short and the transition between the drawn shadow and the rest of the scenery is often so stark it would be very helpful for the players who don’t want this shadow line in front of them to be able to disable shadows altogether. In lots of instances it would make the game look better, be more immersive and have fewer distracting scenery changes, although it would of course look a little shadowless. This is why it would be a choice in the settings, because it’s nice to have the choice. I’m confident some performance issues may improve as a side effect of this option too. It would be a very popular addition to the settings menu, especially on console where the shadow distance problem is most pronounced.
The setting could be added in with the other shadow settings. The shadow quality setting could scroll through high, medium, low, off.
