Ray Traced Shadows within World of Warcraft Shadowlands have now been enabled on the game’s Beta/PTR, and the first comparison shots have now surfaced online.

Back in April of this year, Blizzard added Ray Traced Shadow options to the game’s Alpha. Unfortunately, actual Ray Traced Shadows weren’t enabled just yet and those in the Alpha were only able to view the new options. According to the option’s description, it “improves shadow quality with ray tracing, which produces shadows with more natural softness, greatly increased precision, and from additional light sources.”
