Regular Windows Remote Desktop Connection (RDP) does not support OpenGL 4.4, which is needed by Enscape to run.
Hardware accelerated OpenGL (that’s the one your graphic adapter provides) is only available locally. If you use Remote Desktop, your application can’t access the hardware accelerated OpenGL and it will end up using Microsoft Generic OpenGL Software Renderer as a fallback.
This is the way Microsoft built it, but they are working on it, so maybe it will be supported sometime in the future.
