There is a limitation between OpenGL and Microsoft Remote Desktop: unfortunately, the Microsoft Remote Desktop technology supports only OpenGL 1.0. Since ARCHICAD uses newer OpenGL technologies (e.g. ARCHICAD 22-23 uses OpenGL 3.3, the previous versions use 2.0), we can only suggest workarounds:
a) Using the Vectorial Engine is an ultimate solution, but of course, quite a painful one.
b) Other remote desktop applications, like Google Remote Desktop can handle newer OpenGL versions, so using them can also help.
c) OpenGL works well with Microsoft Remote Desktop if ARCHICAD is started before the remote. So, join to the computer with Google Remote Desktop or Teamviewer, start the project, then leave the session and join with Microsoft Remote Desktop afterwards.
d) If both computers are Windows 10, switching ON Hardware acceleration in ARCHICAD (Work Environment > Advanced Redraw Options > 2D Drawing Hardware Acceleration: FULL – it is switched OFF by default) might solve the issue. Unfortunately, according to our tests, this doesn’t always help.
