Removed mention of 'both graphic clients' from README

README.md

@@ -67,16 +67,6 @@ If you want to build the documentation, you need a few additional tools:
 - [Doxygen](https://www.doxygen.nl/index.html) for building the source-level
   documentation for developers.
 
-By default, the build is configured to create both graphics flavours of the
-Orbiter executable (although this can be configured with the ORBITER_GRAPHICS CMake flag):
-- ``orbiter.exe`` is the standalone Orbiter application with built-in DX7 graphics.
-- ``orbiter_ng.exe`` is a launcher for ``./Modules/Server/orbiter.exe`` which is the
-graphics server version of Orbiter. It requires an external graphics client
-plugin to be loaded via the Modules tab of the Orbiter Launchpad dialog.
-The reference D3D7Client is included with the build with essentially the same
-functionality as the built-in graphics version. Use 3rd party client
-implementations to make use of more modern graphics engines.

 See [README.compile](./README.compile) for details on building Orbiter.
