We’ll use the Tanks! project that is available for free on the Unity Asset Store for this tutorial. You’ll also find summaries of all the API calls that can be used. More detailed description of the plugin, its requirements, and its use may be found in the included documentation. The package contains a Plugins subfolder with the required DLLs (Dynamic Link Libraries) and a Scripts folder which adds a script when the plugin is imported into your Unity project. You can download the plugin from the Unity Asset Store.

The NVIDIA Highlights plugin currently supports only 64-bit Windows. Developers can download the latest GeForce Experience client here. The plugin interfaces with Geforce Experience in the background so a compatible version of GeForce Experience needs to be installed.

NVIDIA built the plugin on Unity 5 and the plugin maintains compatibility with future versions of the engine. The plugin works with both Pro and Free versions of Unity. This blog introduces basic concepts a developer needs to implement the NVIDIA Highlights plugin for the Unity game engine. (You can check out more information about ShadowPlay here).
