Description

As APIs get older, their maintenance or support may eventually deteriorate or outright dropped, which can lead to numerous compatibility and performance issues in older games. To circumvent these and allow older games to be played with as few issues as possible, display API wrappers can be used as a compatibility layer that intercepts instructions at runtime which the game sends using older or obsolete APIs and converts them to a different, but newer, API to make use of more modern alternatives (like newer Direct3D, OpenGL or Vulkan). This process is opaque to the game, leaving it unaware that the display API it was developed for is not the one actually being used. Hence, wrappers most often have the same filename as the game's original wrapper to be properly called on every launch.
