title: VirtualBox: OpenGL version limited to OpenGL 2.1
body: <p>my computer is running on windows 7 with <strong>OpenGL 4.5</strong>. The graphic card is an ATI HD 5470. When I launch my virtual machine (Ubuntu 15.10 32-bit) with VirtualBox and the guest additions installed:</p>
  
  <p>-enabling 3d acceleration, I can only use <strong>OpenGL 2.1</strong></p>
  
  <p>-disabling 3d acceleration, I can only use <strong>OpenGL 3.0</strong></p>
  
  <p>I need to have my virtual machine using <strong>at least OpenGL 3.2</strong>, because I am trying to compile geometry shaders. How can I do that?</p>
