MESA3D FOR WINDOWS -- http://mesa.fdossena.com This library provides software rendering capabilities to OpenGL applications. Note that software rendering is a LOT slower than 3D accelerators, so this library should only be used as a last resort, with old OpenGL games that won't run on newer hardware. To use Mesa3D, simply extract opengl32.dll in the same directory as the application executable. (right click the shortcut > Open File Location, this is where you should extract it)
