In Performance Monitor, According to document, The function, Frame Trigger(ms), can catch specific frame how many time it take infomation about cook, but In below this case, I wanna catch performance log when the program cooked in 1seconds, but it have black block all the time.
This is a frame trigger. So if the frame takes 1 second to cook, then it will show here.
The Performance Monitor only reports a single frame of data, not over a time range.
