Arm has officially opened its Accuracy Super Resolution (ASR) upscaling technology for developers, making it accessible for integration into mobile games. Announced at the Game Developers Conference (GDC) 2025, Arm plans to release straightforward plugins for popular game engines like Unity and Unreal Engine by the year’s end. This open-source solution aims to enhance the Android gaming experience, providing a powerful alternative to Apple’s MetalFX.
Technical Specifications and Performance
Traditionally, Arm’s chips are found in smartphones; however, they are also making their way into laptops with Qualcomm’s Snapdragon X series SoCs. As a result, it’s anticipated that ASR will support these devices as well. Built on AMD’s FidelityFX Super Resolution 2 technology, initial reports indicate that ASR can deliver a 53% increase in frames per second (FPS) at 2x upscaling when used with the Immortalis-G720 GPU, specifically in the Dimensity 8400 and 9300 chips. Furthermore, using ASR at 2x upscaling on the quality preset reportedly results in a 20% reduction in power consumption.
Impact on Mobile Gaming
Mobile upscaling technologies often prioritize performance over visual quality, which can lead to limitations. For instance, Qualcomm’s GSR faced challenges due to hardware constraints and limited game support. In contrast, the open-source nature of ASR allows developers to customize it according to their specific needs. Notably, Arm demonstrated ASR in Unreal Engine 5 during the “Mori” demo, claiming it achieves up to a 30% performance boost without compromising visual fidelity.
Integration and Compatibility
Arm’s promotional efforts include a new chapter in the Mali Manga series, showcasing ASR as a viable option akin to NVIDIA’s DLSS or AMD’s FSR for mobile platforms. The integration of ASR within Unity and Unreal Engine is designed to be user-friendly, enabling game developers to implement it with minimal effort. Anticipated titles featuring ASR integration include popular games such as Genshin Impact, Wuthering Waves, and Fortnite.
While ASR is primarily designed for mobile SoCs, it is expected to be compatible with a variety of hardware, including Qualcomm’s Snapdragon, MediaTek’s Dimensity, Google’s Tensor, Samsung’s Exynos, and Apple’s A-series and M-series chips. Developers seeking to incorporate ASR into other game engines may face additional challenges, but the capabilities of ASR are designed to be broadly adaptable across different platforms.
