NX is a compression protocol for X, so the Windows client has to bundle an X 
server. It sounds like the bundled server only supports OpenGL 1.2 while 
Exceed-3D supports 1.3 or above. On linux the client just uses the local X 
server which usually has good OpenGL support these days.

You could try xming or xorg/cygwin in place of Exceed as they _might_ have 
better OpenGL support than the bundled xorg/cygwin.
