## Introduction

Follow these steps to implement **Arm Accuracy Super Resolution (Arm ASR)** in your custom engine.
Follow these steps to implement **Arm Accuracy Super Resolution (Arm ASR)** in your custom engine.

Arm ASR is an optimized variant of [Fidelity Super Resolution 2](https://github.com/GPUOpen-LibrariesAndSDKs/FidelityFX-SDK/blob/main/docs/techniques/super-resolution-temporal.md) (FSR2) that includes extensive mobile-specific optimizations, ensuring high performance on mobile devices.

## Performance
Depending on your target hardware and operating configuration, Arm ASR will operate at different performance levels. The table below compares the rendering performance of two Arm GPUs (Immortalis-G715 and Immortalis-G720) when using different upscaling settings at two target resolutions.
