Yet frame-time stability, traversal stutter and shader precompilation still need improvement.

Unreal Engine 5 has reached a new milestone release, version 5.4.

Logically, this makes sense.

Enter Unreal Engine 5.4.

In a CPU-limited scenario on a Ryzen 7 7800X3D, the frame-rate is 42 percent higher in 5.4.

That’s great news for PC, but it’s also a boon for consoles.

When flying through the city, stressing the CPU more, that differential shifts to 80 percent.

As I’ve pointed many times in Digital Foundry articles, UE has a big shader compilation stutter issue.

Frame health could also be improved.

Beyond performance, the updates to Unreal Engine since the 5.0 release have included interesting visual improvements.

Version 5.4’s reflections also exhibit more detailed and realistic textures and materials in reflections, plus ray-traced shadows.

This feature is currently experimental, but footage provided by UE specialist Dylan Browne from Model Farm is impressive.

This gives the appearance of a boiling and uneven moving surface all across the model - very cool.
