Unreal Engine 5.7 will have a major upgrade! The speed is almost doubled compared to Unreal 5.5

　　Unreal Engine 5 is very popular for its stunning picture performance, but lags and high hardware requirements have always been pain points for developers. To address these issues, Epic Games has significantly optimized performance in Unreal Engine 5.7 preview, greatly improving smoothness and hardware compatibility.

According to Epic's introduction, the new version of the programmatic content generation (PCG) framework has reached a level close to the production environment, and its speed has almost doubled compared to UE5.5, thanks to GPU generation optimization and game thread performance tuning. In addition, the PCG editing mode also adds customizable tools and independent operation functions of charts, further improving development efficiency.

　　UE5.7 also launched an experimental programmatic vegetation editor, allowing developers to directly use Fab resources to generate high-quality vegetation adapted to Nanite in the editor, making large-scale and detailed vegetation scene processing more efficient.

　　In addition, MegaLights directional light and particle light have also entered the testing stage, bringing a more realistic lighting effect. Performance tuning features have been enhanced, and developers can more flexibly manage resolution scaling and rendering effects, further improving game performance and smoothness. The experimental support of Nanite vegetation has also entered a new stage, and developers can render dense, high-detailed vegetation scenes smoothly at 60 frames on modern hardware.

　　It is worth mentioning that Epic Games cooperated with CD Projekt Red to apply the latest features of UE5.7 to "The Witcher 4".
