PC speed slows down on server side

[XABIBASTIDA1]

Hello,
Ultravnc is already installed in one PC.
I use Ultravnc VIewer in other pC and connection is good.However,
when I handle the server's PC some HMI application, from the viewer, this application's speed slows down in a considerable way.
I am connected in the same LAN.
Maybe some incompatibility between Ultravnc server and the application which speed slows down?

Thank you.

OS
taskmgr what's the cpu load
What capture mathod are you using

You can lower the cpu setting ( server options, capture) less fps but also less cpu usage.
Use other encoder like video, this use less cpu then zrle/tight
