CD Projekt RED pulled out a rabbit out of its hat, revealing the first trailer for the upcoming The Witcher IV title. The new trailer is pre-rendered in a custom build of Unreal Engine 5, which CD Projekt RED is now using instead of its own in-house engine, as announced earlier. More interestingly, it is pre-rendered on an "unannounced NVIDIA GeForce RTX GPU." CD Projekt RED teamed up with Platige Image, who were responsible for intro cinematics in the previous Witcher games.

The trailer, which is almost six minutes long, follows Ciri, which confirms earlier rumors that the game might focus on Ciri as the main character. As detailed by CD Projekt RED, the trailer shows Ciri's new abilities and tools, as well as a small part of the story, a witcher contract set in a remote village. CD Projekt RED is promising that The Witcher IV will be "the most immersive and ambitious open-world Witcher game to date."
 
In the nearly six-minute trailer, viewers were introduced to Ciri, the adopted daughter of Geralt of Rivia, as she takes on a witcher contract in a remote village that has been terrorized for generations by a fearsome monster demanding human sacrifices. Framed as a short, self-contained Witcher story, the trailer showcases Ciri's new abilities and tools, including a chain and advanced magic powers.

At the heart of the trailer is Ciri's perspective as an outsider to the village. As the villagers say goodbye to one of their own - a young girl they are preparing for a traditional ritual sacrifice - Ciri chooses to intervene. Aiming to slay the beast and save the girl at the same time, Ciri finds herself at odds with the prejudices and superstitions of the people she tries to protect, leading her to confront a painful witcher lesson: that monsters come in all forms.
 
Looks like this game was pre-rendered on a next gen NVIDIA GPU or an NVIDIA GPU next gen engineering sample
