+# glxgears for Windows - OpenGL Demo & Benchmark Tool
+
+This repo is a windows port of the common unix opengl application glxgears. 
+
+Glxgears is a common tool for testing the OpenGL rendering pipeline and gives a simple fps benchmark from the gears animaiton.
+
+This particular port is compiled in Visual Studio 2012 and it should be very easy to uprade this project for newer versions of visual studio (2013/2014+).
+
+Unfortunately this tool is now very dated - it makes use of the old style OpenGL fixed rendering pipeline which has been deprecated for a long time (https://www.opengl.org/wiki/Fixed_Function_Pipeline).
+
+A more modern approach would be to use things like shaders - the rendering pipeline is actually emulated with shaders as of 2.0+
+
+If ported, this application may not work correctly with the OpenGL-ES specification (mobile devices). 
+
+The original glxgears application was written by Brian Paul in 1999-2001 his license/warranty is provided within the source-code.
