Mouse behavior in game very slow. Logging shows LOTS of ntdll.RtlFreeHeap() / ntdll.RtlAllocateHeap (,,,) which may make the game very slow.
Attached the output of WINEDEBUG=+relay wine Startup.exe >&/tmp/output.txt starting from the main screen view (so excluding all logging while booting). At the end, I quit the application: at that point, only a black screen was shown.
Lots of ntdll.RtlFreeHeap does not mean that it is a cause for your program running slow. It's more than likely normal behaviour, but in any case there is no point in just guessing. If you want to find out where time is being spent you need to use a profiler such as oprofile.
