- A new UE5 feature, MegaLights, massively improves the RTX 4080’s performance at 4K by up to 50%.
- Introduced in Unreal Engine 5.5, the feature enhances performance and image quality over base Lumen.
- It lets developers add dozens of dynamic shadow-casting lights without any limits.
Unreal Engine 5 has become the most standardized game engine in the AAA industry, causing a wave of positive and negative yields across studios. While UE5 is celebrated for delivering great visuals, it is also critiqued for high system requirements, killing creativity, and performance issues. However, Epic Games might finally be addressing the performance dilemma.
Unreal Engine 5.5 has introduced a new feature dubbed MegaLights, which promises notable performance boosts. The RTX 4080 saw a performance bump of up to 50% at 1440p and 4K resolutions using the new option.
Why it matters: The new MegaLights feature has led to a huge performance upgrade for the RTX 4080 at 1440p and 4K resolutions, suggesting that it may finally address the performance issues that plague UE5-based AAA titles.
A YouTube video by MxBenchmarkPC shows a comparison of Quixel’s UE5.5 Dark Ruins tech demo. It uses an RTX 4080 with software Lumen, hardware Lumen only, and hardware Lumen with MegaLights configurations to highlight the significant difference.
Epic Games’ new tech enhances performance while also improving visual fidelity at various high resolutions to a noticeable extent. The feature lets developers add hundreds of dynamic, shadow-casting lights without having any old restrictions.
As a result, MegaLights is expected to be a game-changer compared to the base Lumen we’ve seen so far. In other words, the micro stutters and lousy optimization issues might finally be resolved in AAA titles.
It is best to take these tech results with a grain of salt since the effect of this new feature might vary across various GPUs and other PC hardware. However, fans agree it is still a substantial improvement over the old UE5.
Do you think this performance enhancement will help more gamers enjoy 4K gaming on the RTX 40 series cards, or is it just a novelty feature? Let us know your thoughts in the comments below, or join the discussion on the official Tech4Gamers forum.
