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?

Which version of UltraVNC are you using? I recommend 1.0.5.6 –  stukelly May 8 '09 at 17:46
    
Just out of curiosity, why bother with VNC when you've got RDP out of the box on Vista? There are basic RDP clients for just about every platform these days. –  Ryan Bolger May 9 '09 at 16:08

This is Vista Home Premium, which does not include RDP. –  Sam Schutte May 11 '09 at 13:25
    
Also note that if you do want to run RDP on Vista Home, there is a way: serverfault.com/questions/6944/… –  Sam Schutte May 14 '09 at 16:56

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

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.

Are you using the UltraVNC Video Driver? The latest is 1.0.5:
