You can still do all of that.
First, the Game Thread in the Timing Panel allows you to see graphically everything that’s happening in the thread. But you want to drill down into a list of what is taking the most time, right? A good way of doing that would be to select a single function which you want to see what is happening underneath it. In this example, I’ll click the FrameTime function:
The Callees Panel will then show you a tree view of every single function that it calls and how long it takes in milliseconds, sorted by the time it took, and even how many times it was called:
You can even select multiple frames to see how long each function has taken in total in that time range:
This includes blueprint, events, and node names. With more data than Frontend was ever able to show. Is this what you were looking for?
