Unreal Engine 5.7 Is A Definite Upgrade That Everyone's Been Waiting For!

Story Highlight
  • Epic Games has now launched the Unreal Engine 5.7 preview, which improves performance and introduces many new features.
  • PCG is nearly twice as fast as UE5.5, thanks to optimized GPU generation and game thread performance tuning.
  • MegaLights directional and particle lighting has moved to beta, and Nanite Foliage rendering paths are in the experimental stage.

Unreal Engine 5 has become the standardized gaming engine for many AAA and even indie developers due to its ease of access features. However, the huge drawback is the slew of performance issues—like stuttering and high system requirements—that come with it. 

Epic Games has been working on ironing out these flaws by improving the performance since the last few updates. The company has now launched the Unreal Engine 5.7 preview, which is a substantial upgrade over the last version.

Why it matters: Unreal Engine 5.7 boosts performance notably compared to 5.6 while introducing many new features for developers at the same time.

Unreal Engine 5.7 preview reveals massive performance improvements and new features.

As explained by Epic, the Procedural Content Generation Framework (PCG) is now production-ready, being almost twice as fast as it was in UE 5.5. This has become possible due to optimized GPU generation and game thread performance tuning.

We’ve continued optimizing GPU generation and game thread performance, and PCG is now almost twice as fast as it was in UE 5.5!

The new PCG editor mode provides customizable tools, while graphs can now run independently. UE5.7 also features a new experimental procedural vegetation editor to let developers produce Nanite-ready foliage directly in the editor using assets from Fab.

You can create and customize vegetation in real time, without having to round-trip with third-party tools and procedurally assemble them into unique tree variations and forests.

Additionally, MegaLights directional and particle lighting has moved to beta. And the new performance tuning controls allow studios to manage resolution scale and achieve better performance with improved noise reduction.

Nanite foliage has now also entered the experimental stage, enabling developers to create dense, high-detail foliage smoothly at 60 fps on current-gen hardware.

Unreal Engine 5 Stuttering Problem
Many AAA Unreal Engine 5 projects are notorious for having stuttering issues.

The update also includes production-ready substrate materials, real-time animation generation from external cameras, improvements to animation and rigging tools, and the AI-powered Epic Developer Assistant.

Epic Games has been working hand-in-hand with CD Projekt Red to implement the latest Unreal Engine 5.7 features in The Witcher 4 ahead of time. So, we already have an idea of these exciting performance improvements via the latest The Witcher 4 tech demo
