Recently, Many gamers upgrading their graphic card for greater gaming experience, so DirectX 11’s coverage is fine to use. Also we can make more realistic game with DirectX 11’s new functions. DirectX 11 is released in 2009. But many games are developed with old version of DirectX. DirectX 11 has new shaders, fixed some uncomfortable things, and has incresed performance. Recently, personal computer parts are getting cheaper, so many user have graphic card that support DirectX 11. In this paper, we invent a game engine with DirectX 11 that resolved the problems and make it easy to make a game engine. Commercial engines are made for general purpose. Self-made engine is perfectly fit with the game. Unlike commercial engine, self-made engine is license-free and we can handle the source code. It allows us many things; attach new technology before commercial engines doing that, Free to implement experimental features, and able to use variety of libraries.
