So, at low graphics quality it basically kills off all the shadows and lighting from the sun, leaving the grass to look like it has no textures, every shadow from the trees are complete gone.
It’s not exactly a thing you can fix, because the engine HAS to disable multiple rendering features if you turn down your graphics quality for extra performance.
Hopefully we get a proper list of settings for the graphics sometime soon…
Yes, but that would be impossible, as either the engine forces it to not render anyway, or if the player purposefully set the quality lower to gain performance, which you defeat the entire point of if you force the game to render more than it allows. The best thing to do is prompt them to increase it.
