Arm has officially unveiled its Accuracy Super Resolution (ASR) upscaling technology at Game Developer Conference 2025, delivering an open-source upscaling solution for mobile and low-power devices. Built upon AMD's FidelityFX Super Resolution 2 (FSR 2) framework, ASR promises up to 53% higher frame rates while reducing power consumption by 20% on devices utilizing the Immortalis-G720 GPU. This technology addresses a critical performance gap in the Android ecosystem, which has historically lagged behind Apple's MetalFX implementation. The temporal upscaling approach employed by ASR combines information from multiple frames to generate higher-quality images, offering superior visual fidelity compared to Qualcomm's Game Super Resolution (GSR), which relies on the older spatial-based FSR 1 technique. In benchmark testing with complex scenes, Arm demonstrated that ASR helps maintain stable device temperatures, preventing thermal throttling that can compromise user experience.

Collaboration with MediaTek confirmed significant power savings on Dimensity 9300 chipsets, directly addressing battery life concerns for mobile gamers. Arm plans to release pre-built plugins for Unity and Unreal Engine by year-end, streamlining integration for developers working with these widely-used game engines. During GDC demonstrations, Arm showcased the "Mori" demo running in Unreal Engine 5, where ASR delivered 30% performance improvements without visual compromises. Licensed under MIT open-source terms, ASR's accessibility extends across the entire Arm ecosystem, potentially benefiting smartphones running MediaTek Dimensity, Qualcomm Snapdragon, Samsung Exynos, and even Arm-powered laptops featuring Snapdragon X series SoCs.

In a community blog post, Arm has announced its new Accuracy Super Resolution (ASR) upscaling technology. This open-source solution aims to transform mobile gaming by offering best-in-class upscaling capabilities for smartphones and tablets. Arm ASR addresses a critical challenge in mobile gaming: delivering high-quality graphics while managing power consumption and heat generation. By rendering games at lower resolutions and then intelligently upscaling them, Arm ASR promises to significantly boost performance without sacrificing visual quality. The technology builds upon AMD's FidelityFX Super Resolution 2 (FSR 2) and adapts it specifically for mobile devices. Arm ASR utilizes temporal upscaling, which combines information from multiple frames to produce higher-quality images from lower-resolution inputs. Even though temporal upscaling is more complicated to implement than spatial frame-by-frame upscaling, it delivers better results and gives developers more freedom.

This approach allows for more ambitious graphics while maintaining smooth gameplay. In benchmark tests using a complex scene, Arm demonstrated impressive results. Devices featuring the Arm Immortalis-G720 GPU showed substantial framerate improvements when using Arm ASR compared to native resolution rendering and Qualcomm's Game Super Resolution (GSR). Moreover, the technology helped maintain stable temperatures, preventing thermal throttling that can compromise user experience. Collaboration with MediaTek revealed significant power savings when using Arm ASR on a Dimensity 9300 handset. This translates to extended battery life for mobile gamers, addressing key concerns. Arm is releasing ASR under an MIT open-source license, encouraging widespread adoption and experimentation among developers. Below you can see the comparison of various upscalers.
