Does Unity have additional dependencies for deployed standalones?

Questions & Answers
1

When publishing a Unity game for Windows, does one have to include additional dependencies such as .NET or DirectX with the installer? If so, which dependencies need to get installed with the game?

Edit:

Note that OpenGL fallback may cause a dramatic performance drop or graphical artefacts. Be sure to test your game with -force-opengl if you won’t be redistributing DirectX. This is not an issue for games targeting Windows XP Service Pack 2 or later since DirectX 9.0c is included in those versions of the Windows platform.

No. The Unity runtime is completely self-sustained within a build - specialised mono runtime included.

If your end user does not have a DirectX 9.0c or newer runtime installed, we will fall back to OpenGL. Notice that you can also force OpenGL mode with the "-force-opengl" command line argument.

For more information about command line arguments, check out the section at the bottom of this documentation article.
