What is ray tracing and what will it do in Shadowlands?
If you're wondering what ray tracing is and why it's a big deal that it's being added to World of Warcraft, with it currently being tested in the Shadowlands beta, it's actually a simple idea -- as part of the beta, a change to lighting in WoW is being tested that allows the game to render multiple light sources and multiple shadows in one area.
