--- Comment #52 from Marek Olšák <mar...@gmail.com> ---
We don't need a debug build. We just need:
1) One person to run the debug build and use sysprof to capture where the CPU
is spending time during the freeze.
2) Make a screenshot of the sysprof window and send it to the game developer.
3) The game developer should look at it and decide what to do next.
sysprof is a very-easy-to-use standalone CPU profiler GUI that you run under
root. It's observing all processes and also the kernel. For apps built with -g
(but also keep -O2 at least), it will show the functions and % of CPU time
spent in them. For apps also built with -fno-omit-frame-pointer, it will show
whole call stacks.
