For now, you can try connecting from the command line to lower the quality: Code: presencevnc vnc://hostname 3 Which VNC server / connection type do you use? With x11vnc over wifi I tend to have a higher framerate and less lag than with vnc-viewer
presencevnc vnc://hostname 3
That's server-side only isn't it? It just affects how the server gets notified of changes to the screen, so there's no direct interaction with the viewer. And there's an open-source equivalent available (search for dfmirage).
