Arm earlier launched aHigh-resolution image enhancement technology called Arm ASR (Arm Accuracy Super Resolution), which is based on the FSR2 technology provided for external use in AMD GPUOpen open source project, so that mobile devices can also respond to high-resolution frame rate improvement effects, comparable to the DLSS, FSR, and XeSS technology effects achieved by PC devices through different GPUs.
At the same time, although FSR2 technology is open source, it is actually designed for use in PC devices. Therefore, in order to apply it to mobile GPUs, Arm has made considerable development and adjustments. It also emphasizes that compared to Qualcomm's GSR (Game Super Resolution) or AMD's initial FSR, which performs per-frame processing enhancements, it will achieve better performance.
This was verified using NVIDIA's open-licensed Bistro 3D scene. By rendering over 280 million polygons, adding more locally overlapping light and shadows, and varying primary ray falloff, the improvement in native 9300p and native 720p images was compared on a MediaTek Dimensity 1080 processor-based device, leveraging its integrated Immortalis-G540 GPU. This confirmed the extent of the improvements achieved with Arm ASR technology.
The performance improvements achieved by Arm ASR technology are significantly greater than those achieved by GSR and FSR technologies, and even better than FSR2. Performance is also significantly improved, even consuming less data transmission bandwidth. Details are closer to native high-resolution imagery, without the blurring or smearing that can occur with other technologies. Mobile games are expected to be presented at higher resolutions while operating with lower performance resources and reducing device power consumption.
