Is there a method to measure desktop application UI response time?

There are C++ desktop application, and i need to measure UI lags because users say that it sometimes lags. How can i implement this ? Tried to use pywinauto with timer start-stop after actions, but it clicks the elements very slowly. On the other side, tried to use SikuliX, it works faster, but very flaky. And another tried solution is uberAgent but it detects all performance subsidence performance, even what is not needed.
