<p class="MsoNormal">If you have to support RDP (as opposed to other solutions), and you have to support clients that lack a GPU etc, then you could build your application against Mesa (with OpenSWR or llvm as the renderer) and I believe it should work everywhere
including RDP.<o:p></o:p></p>

<p class="MsoNormal">From what I could find nvidia only supports hardware RDP on their professional cards. It would certainly be nice if vendors would do what they can to support modern OpenGL more broadly in cases like this.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<br>
<br>
Problem description: Application uses VTK 7.0 (OpenGL 2 module) for<br>
rendering on Windows platform. But the problem is, that OpenGL 2 has limited<br>
support over Microsoft's Remote Desktop. RDP is a must for our application<br>
(VNC, TeamViewer is not an option). On Win 10 there is an option called 'Use<br>
hardware drivers over RDP' and it works, but for limited set of video<br>
adapters - AMD, Integrated Graphics from Intel and NVIDIA (Tesla, Grid<br>
only).<br>
<br>
Is there any workaround for this problem, i.e. detect GL version at runtime<br>
and use 1.1 or 2.0? If no, we are going to switch for OpenGL 1.1.<br>
<br>
We concern about OpenGL 1.1 support in future versions of VTK. Is it going<br>
to be supported and how long?<br>
<br>
Best Regards,<br>
Vladimir.<br>
