Arm Unveils Neural Dawn, First Mobile Game to Run Unreal Engine 5 MegaLights with Ray Tracing
Arm Holdings announced that its next‑generation Mali G1 GPU will bring advanced rendering capabilities—ray tracing, neural upscaling, and Unreal Engine 5’s MegaLights—to Android devices later this year. In partnership with UK studio Sumo Digital, Arm is showcasing the new hardware in a short demo called Neural Dawn.
Neural Dawn is slated for release in the fourth quarter of 2026 on devices powered by the forthcoming Mali G1 GPU. The demo is designed to prove that mobile graphics chips can deliver high‑quality upscaling, denoising, frame generation, and ray tracing with a large number of dynamic lights. It is the first mobile title to employ Unreal Engine 5’s MegaLights, a feature that until now has been confined to high‑end consoles and PCs.
MegaLights, introduced in 2024, lets games render scenes with many dynamic light sources while keeping performance costs manageable. It achieves this by estimating the directions of most lights from a carefully chosen set of primary lights. The feature has already appeared in Microsoft’s upcoming Gears of War: E‑Day, and adding ray tracing expands the number of visible lights, raising the load on the rendering engine. Arm’s Mali G1 is engineered to handle that increased demand.
The Mali G1 first appeared as part of Arm’s Lumex platform in late 2025. Mobile processors featuring the GPU have shown marked improvements in ray‑tracing performance over the previous Immortalis‑G925 generation. The new Mali G1 adds neural upscaling technologies that mirror Nvidia’s DLSS, including Ray Reconstruction and Frame Generation. Its Neural Super Sampling and Denoising (NSSD) and Neural Frame Rate Upscaling (NFRU) features aim to deliver desktop‑class visual quality while preserving battery life.
Sumo Digital explained to Digital Foundry that combining MegaLights with the new neural techniques allows Neural Dawn to display dozens of ray‑traced light sources at roughly 30 frames per second. Implementing MegaLights consumes about half of the game’s rendering budget—comparable to more traditional alternatives. While the NSSD and NFRU features are still being refined, their final performance impact remains to be determined.
Arm highlighted that the Mali G1’s neural technology can upscale and enhance graphics on smartphones, tablets, and other mobile devices. The company described the approach as an “industry first,” promising PC‑level visual quality on mobile hardware.
Neural Dawn is a technical showcase rather than a commercial game. It is meant to illustrate how neural graphics can enable developers to deliver real‑time cinematic lighting techniques on mobile hardware. The demo’s release will coincide with the launch of the new Mali G1 lineup, which is expected to appear in high‑end Android phones and tablets later this year.
Although the exact list of devices that will support the new Mali G1 GPU has not yet been announced, Arm has indicated that the chip will be integrated into future Android SoCs. The company’s focus on machine‑learning performance and energy efficiency suggests that the GPU will suit devices requiring both high graphics performance and battery longevity.
Neural Dawn’s demonstration of ray tracing and MegaLights on mobile hardware marks a significant step toward bringing desktop‑class visual effects to smartphones. The combination of hardware ray tracing, neural upscaling, and advanced lighting techniques could influence future mobile game development, encouraging studios to adopt more sophisticated rendering pipelines.
The demo’s release in Q4 2026 will give developers and hardware manufacturers a concrete example of what is possible with the new Mali G1 GPU. It will also offer consumers a glimpse of the visual quality they can expect from next‑generation Android devices.
In short, Arm’s Mali G1 GPU will support ray tracing, neural upscaling, and Unreal Engine 5 MegaLights; Neural Dawn will be the first mobile game to showcase these features; and the demo will launch later this year on devices equipped with the new GPU. The broader impact on the mobile gaming market remains to be seen as developers explore the capabilities of the new hardware.
