Hello
I have noticed, with the latest version of UltraVNC, and the video hook (even when idle) disables 2D DirectX acceleration AND AGP Texture acceleration. In order to get these two back, I have to uninstall the video driver.
I have an Acer Ferrari 4000 laptop, with the latest ATI drivers, Windows XP Home.
Update: UltraVNC 1.4.3.6 and UltraVNC SC 1.4.3.6: https://forum.uvnc.com/viewtopic.php?t=37885

Re: Video Hook & DirectX
Normal, when the video driver is diabled, it should have no impact
on the real video card.
However, when you are runnning as a normal user, and you don't have permission to change the bit in the registry that enable/disable the
mirror driver, it keeps continous running in the background.
In tha case
check
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\SERVICES\vncdrv]
in DEVICES the key Attach.ToDesktop need to be world readable
and writable.
=0 -->disabled after resolution change
=1 -->enabled after resolution change
on the real video card.
