I discovered the command perfmon /sys /comp and that seems to allow me to launch it in "transparency mode" among other things.

I'm lacking a creative mind right now, but when would this be useful?

What do those switches mean separately?

Are there additional commands for this utility?

It simply launches the Performance Monitor log Compare tool.

The "transparency" mode enables you to open another log file from a similar data set, and have the windows open over a non transparent window, so you can compare the graphs
