Months after announcement, Arm is finally making its ASR (Accuracy Super Resolution) upscaler open to developers to integrate into their games. At the GDC (Game Developer Conference) 2025, Arm promised pre-built and easy-to-integrate plugins for games developed using the Unity and Unreal Engine game engines by the end of the year. Arm’s ASR fills a void in the Android gaming landscape, offering an open-source upscaling solution that was previously absent, thus lagging MetalFX in Apple’s dugout.
It’s important to understand that while Arm chips are traditionally found in smartphones, they’ve started to make their way to laptops like Qualcomm’s Snapdragon X series SoCs. So it’s not far-fetched to believe this technology will support those chips as well. ASR is built on AMD’s FidelityFX Super Resolution 2 technology, and at its initial unveiling, Arm claimed 53% more FPS at 2x upscaling with the Immortalis-G720 GPU (Dimensity 8400 and 9300). At the same time, ASR is claimed to deliver power savings of 20% with ASR set to 2x upscaling using the quality preset.
