Hello, I am working on a project which requires me to record reaction time with millisecond accuracy. Labview 8 is able to run at 1000hz in Windows, however I have to know the delay from the program to the monitor (as Windows is performing several tasks, this time is unknown). One way to do this is using the vertical sync (directx). Is there any way to access Directx in Labview or is there any other way to get my timing?
