Did you try something besides adapting xfreerdp to xcb, which > would reduce the overhead associated with X11? xcb proved to be slower then x11 (except if we did something wrong). We started adding the capabilities and the one that improves the performance quite a bit (making it at same level of rdesktop) is the polygon but that has some cases it fails and we didn't find the reason of the failure. This would be nice to be put on the GDI library since it could speed up the drawing. > Also, if the system did not > have hardware acceleration, doesn't that also mean that in this case > xfreerdp doesn't benefit from it and ends up doing software rendering?
