+# Snapdragon™ Game Super Resolution 2.0 Sample
+
+## Overview
+
+Snapdragon™ Game Super Resolution 2.0 (Snapdragon™ GSR 2.0 or SGSR 2.0) sample demonstrates how to integrate SGSR2.0 to do temporal upscaling.
+
+## Build
+
+### Dependencies
+
+The following dependencies must be installed and the appropriate locations should be referenced in the `PATH` environment variable.
+
+* Android SDK
+* Andorid NDK
+* Gradle
+* CMake
+* Android Studio
+* Other dependencies
+   Run following commands at {root_of_this_repo}\GLES_Sample_Framework:
+   ```
+   .\deps.bat
+   ```
+   Make sure all the dependencies are cloned correctly. In my case, the submodules of adreno-gpu-opengl-es-code-sample-framework often failed to be cloned, to solve this try following commands repeatedly:
+   ```
+   cd {root_of_this_repo}\GLES_Sample_Framework\adreno-gpu-opengl-es-code-sample-framework
+   git submodule update --init --recursive
+   ```
+   After all the submodules are cloned, run `.\deps.bat` again to build dependencies.
+
+### Build
+There are two samples demonstrate 3 variants of SGSR2.0.
+- For SGSR2.0 2/3-pass compute shader variant, uses the sgsr2 sample
+Open Android Studio and go to `File->New->Import Project...` and select the `adreno-gpu-opengl-es-code-sample-framework\samples\sgsr2\build\android` folder as the source for the import.
+
+- For SGSR2.0 2-pass fragment shader variant, uses the sgsr2_fs sample
+Open Android Studio and go to `File->New->Import Project...` and select the `adreno-gpu-opengl-es-code-sample-framework\samples\sgsr2_fs\build\android` folder as the source for the import.
+
+### Evaluation
+Tapping the left part of screen switches SGSR 2-pass/3-pass/off.
+Tapping the right part of screen switches from camera move to still to compare the visual quality better.
+
+
+## Implementation Example
+The core of the integration of SGSR2.0 is
+```
+VOID CSample::PrepareSGSR()
+```
+and
+```
+VOID CSample::DispatchSGSR()
+```

+# Snapdragon™ Game Super Resolution 2.0 Sample
+
+## Overview
+
+Snapdragon™ Game Super Resolution 2.0 (Snapdragon™ GSR 2.0 or SGSR 2.0) sample demonstrates how to integrate SGSR2.0 to do temporal upscaling in two or three GPU shader passes.
+
+### Variants:
+
+- **2-pass-fs  (recommended)**: Uses 2 fragment shaders, favors speed, and is often optimal for Mobile and VR/XR applications.
+- **2-pass-cs**: Uses 2 compute shaders, favors speed, and is often optimal for Mobile and VR/XR applications.
+- **3-pass-cs**: Uses 3 compute shaders, favors visuals, and is often optimal for Desktop/Console and higher-end Mobile applications.
+
+## Build
+
+### Dependencies
+
+The following dependencies must be installed and the appropriate locations should be referenced in the `PATH` environment variable.
+
+* Android SDK
+* Andorid NDK
+* Gradle
+* CMake
+* Android Studio
+
+Before building any sample, run 03_BuildTools.bat at the root of the repository to ensure that all executables any sample might need are built.
+
+At this point, building this sample APK is as simple as navigating to the `build\android` folder and on a command prompt using the following gradle command:
+
+```
+
+$ gradlew assembleRelease
+
+```
+
+Building a slightly-slower executable with asserts can be done with:
+
+```
+
+$ gradlew assembleDebug
+
+```
+
+
+This sample can also be easily imported to Android Studio and be used within the Android Studio ecosystem -- including building, deploying, and native code debugging.
+
+To do this, open Android Studio and go to `File->New->Import Project...` and select the `build\android` folder as the source for the import. This will load the gradle configuration, at which point the sample can be used within Android Studio.
+
+### Evaluation
+Tapping the left part of screen switches SGSR 2-pass-fs/2-pass-cs/3-pass-cs/off.
+Tapping the right part of screen switches from camera move to still to compare the visual quality better.
+
+
+## Implementation Example
+The core of the integration of SGSR2.0 is
+```
