VNC on Vista

  • 772

I'm using UltraVNC on my Vista machine, and it's giving me very poor performance, even over a 300 mbs network. It seems to be doing screen polling.

I looked, and it doesn't look like the video hook driver is working. Does anyone know if you can use a video hook driver with Vista?

    Yes you can install the video hook driver on Vista, but you have to do it manually.

    To improve speed, right click on the UltraVNC icon on the taskbar and select properties. Then tick the following boxes:

    • Poll Full Screen
    • Poll Foreground Window
    • Poll Window Under Cursor
    • System HookDll

    enter image description here

    If you are using the video hook driver, check if the Video Hook Driver option is ticked.

    Then press OK to save the new settings.
