Not sure what thing you are talking about -- but some/many opengl
progs seem to work with XWin across a local network (using programs
on my linux box, and display via Cygwin X).
Many of them operate at full speed, but depends on application:

I don't understand what you mean by this -- I can move the rendering
window around and resize it and don't see any other windows needing
a refresh (most are Xwin from my linux box).
Anyway, thought I'd chime in. Of note --
glxgears sometimes works but is often frozen upon startup.
