- Unreal Engine 5.7 shows notable performance improvements over 5.4 in both CPU and GPU-bound scenarios.
- CPU improvements in the Venice Tech demo were as great as 35% with fewer hitches.
- Meanwhile, GPU performance on an RTX 5080 increased by 25%, as 5.7 uses GPU resources more efficiently.
Ever since Unreal Engine 5.7 was revealed with the Witcher 4 tech demo, gamers have been curious to see all the improvements it brings. Epic Games also promised major fixes, including speed, stability, and better lighting, and it seems to be delivering on them.
A new comparison between UE 5.7 and 5.4 shows huge improvements in both CPU- and GPU-bound scenarios. Image quality is much better. Version 5.7 delivers more stable Lumen lighting and better reflections, at a lower performance cost.
Why it matters: The comparisons show Epic Games is fixing the engine’s biggest hiccups. These improvements could enable AAA games to have better system requirements and improved visuals in the future.
The comparison video shows both versions side-by-side on the Venice Tech Demo map. The GPU-bound scenario shows improvements of up to 25% on the RTX 5080 over 5.4, as the new UE5 version utilizes GPU resources more efficiently.
However, the GPU power draw is also higher, at 300W at native 1440p and up to 350W at native 4K in the 5.7 build. Meanwhile, the power draw in UE 5.4 never exceeded 300W.
GPU performance is improved by up to 25% in UE 5.7 (depending on a scene), and the 5.7 version is now better utilizing GPU resources.

For the CPU-bound test, an Intel Core i7-14700F was used, with the resolution set to 720p and the power limit set to 90W to ensure the test was fully CPU-limited for 5.7. The testing revealed a stunning 35% performance boost compared to 5.4.
UE 5.7 also seems to resolve one of the biggest issues with UE5, as there were significantly fewer hitches or microstutters across all scenes.
UE 5.7 offers a significant up to 35% CPU performance boost (depending on a scene) and more stable frametimes with less hitches across all scenes.
The Unreal Engine 5.7 brings more consistent frame rates and gorgeous visuals, so the averages are much better. However, some spikes and 1% lows still need smoothing for the gaming engine to become the perfect choice for developers.
