Since realtime updates to display overlays seem to add significant processing overhead, I was wondering what the nominal overlay update frequency is. Does anyone know?
As a quick test, I wrote system time to a text file every 100ms and specified the text file as an overlay to be updated in realtime. The result was Blue Iris updates the overlay at least every 100ms.
This caused me to think about the possibility of realtime update frequencies being configurable to possibly lessen the load on the system.
For example, I wrote a Powershell script to pull weather data every minute from my backyard station and display temperature, etc. It works fine, but updating the overlay 10 times a second is overkill for this use.
