Recently, Epic officially launched Unreal Engine 5, which has improved in various aspects compared to the previous Unreal Engine 4.
The most significant change to Unreal Engine 4 is the introduction of new designs for more realistic visuals, including Lumen, a Full Motion Global Illumination Solution, and Nanite, a Virtualized Polygon Geometry System, with numerous upgrades at the performance and UI levels.

Epic first introduced the first generation of Unreal Engine in 1998, and since then the product has been widely used in the game industry, based on which countless well-known game masterpieces have been born. With the official release of UE5, the software will be widely used in PC games, VR games, metaverse-related products, and film and television productions.
In this release, the well-known game developer Crystal Dynamics said that it is using Unreal Engine 5 to create a sequel to Tomb Raider, while CD Projekt RED also announced that it will use Unreal 5 to develop the Sequel to The Witcher.
In addition to these well-known foreign game developers, many Chinese game companies such as Tencent, Mihayou, Game Science, Perfect World and Zulong Entertainment are also Partners of Epic.
As the next generation of real-time rendering engines, UE5 offers a new "full dynamic global illumination solution" Lumen that reacts in real time to scene and lighting changes without the need for cumbersome ray-tracing hardware, which Epic says enables diffuse reflections that bounce infinitely in complex scenes.
Unreal 5 also introduced the new "Virtualized Polygon Geometry System," Nanite, where artists can use it to import hundreds of millions of polygon-shaped art images directly into Unreal Engine, regardless of polygon budgets and draws budgets.
Epic management believes that open-world games based on Unreal 5 can be seen as similar to metaversics.
