=== Software ===
Computer games also rely on [[Third-party software component|third-party]] software such as an [[Operating system|operating system (OS)]], [[device driver]]s, [[library (computing)|libraries]] and more to run. Today, the vast majority of computer games are designed to run on the [[Microsoft Windows]] family of operating systems. Whereas earlier games written for DOS would include code to communicate directly with hardware, today [[API|application programming interfaces (APIs)]] provide an interface between the game and the OS, simplifying game design. Microsoft's [[DirectX]] is an API that is widely used by today's computer games to communicate with sound and graphics hardware. [[OpenGL]] is a [[cross-platform]] API for graphics rendering that is also used. The version of the graphics card's [[device driver|driver]] installed can often affect game performance and [[gameplay]]. In late 2013, [[AMD]] announced [[Mantle (API)|Mantle]], a low-level API for certain models of AMD graphics cards, allowing for greater performance compared to software-level APIs such as DirectX, as well as simplifying [[porting]] to and from the [[PlayStation 4]] and [[Xbox One]] consoles, which are both built upon AMD hardware.<ref>{{cite web|url=http://www.tomshardware.com/news/amd-mantle-api-gcn-battlefield-4,24418.html|title=AMD's Mantle API Gives Devs Direct Hardware Control|date=September 26, 2013}}</ref> It is not unusual for a game company to use a third-party [[game engine]], or third-party libraries for a game's [[Artificial intelligence (video games)|AI]] or [[game physics|physics]].
