Wallpaper Engine is an application for Windows with a companion app on Android which allows users to use and create animated and interactive wallpapers, similar to the defunct Windows DreamScene. Wallpapers are shared through the Steam Workshop functionality as user-created downloadable content. It features its own rendering engine and provides a wallpaper editor, allowing for the creation of 2D and 3D wallpapers, including a particle system editor and a fork of JavaScript called SceneScript for additional wallpaper logic. It also supports using video files, audio files, web-pages and some 3D applications as wallpapers.

A proposal outlining the general idea of the software was added to Steam Greenlight in December 2015. The application was subsequently released as a paid product on Steam in October 2016 as an early access title. After three years of development, the software left its early access stage in November 2018. In August 2019, Wallpaper Engine was announced to be one of the release titles for Steam China.

Despite not being a game, Wallpaper Engine is one of the most used apps of Steam, being located in Steam's Top 25 played games in July 2019 and Top 10 played games in November 2021.

GeForce is a brand of NVIDIA's family of GPUs and motherboard chipsets aimed at the consumer market. GeForce GPUs are mainly used in video adapters for personal and portable computers.

GeForce is a brand of graphics processing units (GPUs) designed by Nvidia. As of the GeForce 30 series, there have been seventeen iterations of the design. The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later diversification of the product line covered all tiers of the PC graphics market, ranging from cost-sensitive GPUs integrated on motherboards, to mainstream add-in retail boards. Most recently, GeForce technology has been introduced into Nvidia's line of embedded application processors, designed for electronic handhelds and mobile handsets.

With respect to discrete GPUs, found in add-in graphics-boards, Nvidia's GeForce and AMD's Radeon GPUs are the only remaining competitors in the high-end market. GeForce GPUs are very dominant in the general-purpose graphics processor unit (GPGPU) market thanks to their proprietary CUDA architecture. GPGPU is expected to expand GPU functionality beyond the traditional rasterization of 3D graphics, to turn it into a high-performance computing device able to execute arbitrary programming code in the same way a CPU does, but with different strengths (highly parallel execution of straightforward calculations) and weaknesses (worse performance for complex branching code).
