Arm Announces an Open-Source Graphics Upscaler For Mobile Phones

Arm is launching its Arm Accuracy Super Resolution (ASR) upscaler that 'can make games look better, while lowering power consumption on your phone,' according to The Verge. 'It's also making the upscaling technology available to developers under an MIT open-source license.' From the reprot: Arm based its technology on AMD's FidelityFX Super Resolution 2 (FSR 2), which uses temporal upscaling to make PC games look better and boost frame rates. Unlike spatial upscaling, which upscales an image based on a single frame, temporal upscaling involves using multiple frames to generate a higher-quality image.

You can see just how Arm ASR stacks up to AMD's FSR 2 and Qualcomm's GSR tech in [this chart] created by Arm. Arm claims ASR produced 53 percent higher frame rates than rendering at native resolution on a device with an Arm Immortalis-G720 GPU and 2800 x 1260 display, beating AMD FSR 2. It also tested ASR on a device using MediaTek's Dimensity 9300 chip and found that rendering at 540p and upscaling with ASR used much less power than running a game at native 1080p resolution.
