[freespace2] Weird behaviour with FS2 CVS Apr 22, 2003

[Taylor Richards]

I posted a patch earlier that seams to fix this.  The basic deal is that
the game will sleep in order to keep the framerate capped at 120fps. 
The problem is that it's locking the thread and making it slow.  The fix
is to change line 38 of src/platform/unix.cpp from:
     usleep (mili * 1000);
to:
     SDL_Delay( long(mili) );

If that doesn't work for you let me know.
