- JPG compression -- you can specify levels of compression. Using RAdmin, it appears that it is setting this level automatically depending on the perceived network speed. Local connections tend to have pretty good graphics presentation, while remote sites clearly have a lot of simplification going on. Plain backgrounds/decorations render far better.
- Map mouse clicks, not movement. How precisely this works I'm not sure as the remote site sees mouse movements, but locally, the mouse is being echoed, er, locally. The feedback lag of having to display a remote tracking of the mouse under VNC is a killer. Makes for much better precision of movement.
Otherwise, the products are pretty similar, but the enchancements are significant.
