What started as a drive to push real-time graphics toward a new generation of immersion has ended up ballooning hardware requirements to the point of absurdity. However, Epic has been making steady improvements, and the latest iteration of the engine, version 5.7, seems to be the best one yet.
Watch On YouTuber MxBenchmarkPC recently tried the 'Venice – Italian City' tech demo by Scans Factory in both Unreal Engine 5.4 and Unreal Engine 5.7, comparing the two across 1440p and 720p resolutions. They used an RTX 5080 GPU and an Intel Core i7-14700F processor for the benchmark, and the results appear very promising.
At 1440 p.m., we see an average difference of 15 FPS between the UE 5.7 and 5.4, with the former always staying ahead. This performance bump, however, came at a cost as Unreal Engine 5.7 consumed up to 1 GB of extra VRAM and system memory compared to UE 5.4 throughout the run.

According to the OP, "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, hence the GPU power draw is now higher." You'll see increased wattages mostly with higher-end GPUs only, as they have that extra headroom to offer.
In a CPU-limited scenario at 720p, the performance gain jumps to 35% as the UE 5.7 actually eats less RAM. This is clearly the bigger impact of UE 5.7, as MxBenchmarkPC confirms in their note, saying: "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."
Apart from better FPS, there's a noticeable image quality improvement too, with more consistent lighting that adds to the immersion. We noticed more accurate shadows in the trees and vegetation, denser raindrops, and significantly better-looking reflections in water in certain scenes. Lumen is evidently living up to its name with this update, though its built-in denoiser is still not as good as Nvidia or AMD's solutions.
Moreover, the point of comparison, Unreal Engine 5.4, is not random here as it's notorious for being hard on GPUs, on top of having stability issues. Subsequent revisions, like Unreal Engine 5.6, have already improved upon it a lot, so a comparison between UE 5.6 and 5.7 won't look as striking — but it's great to see a step in the right direction regardless.
