--- Comment #9 from Jonas Maebe jonas.bugzilla@gmail.com --- Created attachment 52585 --> https://bugs.winehq.org/attachment.cgi?id=52585 Sampling profile trace of the ddraw/game logic thread
As mentioned in the comment referring to this profiling data: note that it's sampling based, but the percentages *include* time spent blocked for kernel operations to complete. That's why the thread is recorded as using 8.5% of the total sampled time, as there are 12 "full time" threads in the program (I guess it's rounded up) and e.g. even threads that do almost nothing but spend time waiting for a select call to finish, are counted just as much as a thread that is constantly calculating.
