Having a dedicated GPU is highly recommended, but not required.
As a general rule of thumb, 3D, 2D and video based wallpapers will perform best, while websites and applications will require more resources from your system. Many options to tweak quality and performance allow you to make Wallpaper Engine fit your computer perfectly. You can choose to automatically pause or completely stop the wallpaper while using another application or playing fullscreen (including borderless windowed mode) to not distract or hinder you while playing a game or working. Wallpaper Engine aims to deliver an entertaining experience while using as few system resources as possible.
Choose an existing wallpaper or create your own and share it on the Steam Workshop! In addition to that, you can use the free Wallpaper Engine companion app for Android to transfer your favorite wallpapers to your Android mobile device and take your live wallpapers on the go. Various types of animated wallpapers are supported, including 3D and 2D animations, websites, videos and even certain applications. Wallpaper Engine enables you to use live wallpapers on your Windows desktop.
