Windows 8 Very Slow or Unresponsive

Post by spetragl »

Installed 1.2.0, same problem as 1.1.9 in W8. The screen loads fine, but then either it's extremely slow, no response, or it misses Windows opening.
I have UltraVnc installed on W7 and XP boxes and it works fine.

Any thoughts how to make this work?

pm the ultravnc.ini ( erase the passwd in it) so we can see the settings.

Are the addons installed ? special the w8hook.dll

try
TurboMode=1
PollUnderCursor=0
PollForeground=0

PollFullScreen=1
OnlyPollConsole=0
OnlyPollOnEvent=0
MaxCpu=40 <<<<<<<<<<<<<<< you throttle updates if cpu ( apps + vnc) is using more then 40% for testing use 0 or 100
EnableDriver=0
EnableHook=1

The mirror driver can be installed on win8, but is slower then the w8hook. Also, the mirror driver require elevated admin access.
If mirror driver is installed, but you don't have permissions to use it all is slow. EnableDriver=0 to disable driver usage.

Not any better.
I did notice that uvnc was using about 2% CPU, while
Windows Desktop Manager was using upwards of 90% !

w8hook installed ?

high wdm indicate a slow memory copy , ultravnc need to be able to fast copy video data between video memory
and system memory what are the system benchmarks.

How do I get benchmarks?
Do you need video card info?
