Wonderware intouch running slow

Hi , i am converting a standalone app to a modern app with many archestra grapchics replacing the old classic ones.. . The thing is that each time I switch from one window to another it takes like 5-8 sec to open it.. Once it is opened is runs correctly...

What could be the issue ? or a way to fix it ??

what are the hardware requirements if im using many archestra grapchis ( valves,tanks,pipes,pumps)

thanks !

Grid lag

On old systems i found that if you have the grid on it gives you the same effect as you are describing

hmmm... anyone has any other idea ? if it is a hardware issue or its common to have this slow response..

thanks
