Very modern apps that use special apis to do lower latency scrolling/resize may be a little better.ģ. Looking at api use from eg X may help with old apps that make small updates but more modern apps (or even modern fonts) which just render to gpu buffers and composite are less amenable to this. There is some trade off of latency for bandwidth: it may take more time to figure out a small change to send over the network. I think the windows server implementation can take advantage of information about the composition of the screen from windows.ġ. I think it does a bunch of raster things (eg maybe caching floating windows like right-click menus).
It has eg commands that correspond to scrolling regions of the screen to save on network use, a framerate limit (25fps I think) and allows some colour space reduction to reduce bandwidth too.
RDP is not as simple as sending draw commands.
