Pretty simple question.
I have put frame markers in using the API, so I can see the frames in the timeline view.
All I want to do is pick a frame (any frame) in the timeline, zoom in on selection, and then search for a function to see how long that function took in that frame. The function in question is not particularly slow, but I do want to know how long it's taking.
I don't seem to be able to do this easily
You can select the frame on timeline on the ruler area (the time region that corresponds the frame should be a bit greyed-out) then invoke context menu (right mouse button click) and choose "Filter-in by Selection". Then in bottom up grid view with grouping "/Function/..." you can try to find the function of interest and see its CPU time that will be filtered by time spent in this frame.
Thanks & Regards, Dmitry
