Dubbed Arm Accuracy Super Resolution (ASR), the tech aims to enhance game visuals while reducing power consumption on mobile phones.

Developers can access this upscaling technology under an MIT open-source license.

The idea is inspired by AMD's FidelityFX Super Resolution 2 (FSR 2) which uses temporal upscaling and multiple frames to generate higher-quality images.

Unlike spatial upscaling (which relies on a single frame), temporal upscaling improves visual quality and frame rates.

Upscaling is crucial for lower-powered graphics cards that struggle to run games smoothly. Existing upscalers (such as AMD FSR, Nvidia DLSS, and Intel XeSS) primarily target desktop and laptop GPUs.

Arm's ASR stands out because it specifically caters to mobile phones, potentially impacting battery life significantly.

Arm claims impressive results for ASR: In a test with an Arm Immortalis-G720 GPU and a 2800 x 1260 display, ASR achieved 53 per cent higher frame rates than native resolution rendering, outperforming AMD FSR 2.

Another test using MediaTek's Dimensity 9300 chip showed that rendering at 540p and upscaling with ASR consumed less power than running the game natively at 1080p.

 Arm-based processors power Copilot Plus PCs from major brands like Microsoft, Dell, Lenovo, and Samsung. It's possible that Arm's lightweight ASR upscaler could also find its way into laptops.

Microsoft's existing Automatic Super Resolution (exclusive to Snapdragon X chips) may soon have company as Microsoft explores additional upscaling solutions for a broader range of Windows devices.
