You think you have come a long way with graphics in gaming, and then something comes along to remind you that 1999 was not all that long ago.
Here we are, in the North Downs, casting double shadows. This is an issue I recall seeing back in EverQuest. I can reproduce this in EverQuest II as well.
Shadows seem like such easy things to us. They just “happen” in real life. In virtual worlds, sometimes the easy is difficult.
This is why I usually turn shadows off.
