Different methods to service the timers that drive it. 1 uses an alarm() call, 2 uses a select() and 3 uses a method that processes each one as they come in. The engine runs fast with a pingboost of 3 and a ticrate over 1000 due to the way the engine divides/multiplies the ticrate to step frame time. You really don't need highres timers on a machine anyways, because when hrtimers are enabled in the kernel the error rate is increased and you see significant jitter doing sleeps.. the long term solution is to write a sleep function that uses the rdtsc of the cpu and then you get ultra accurate sleeps (you'll need a reference clock though, like open /dev/hpet or use ntpd :-) _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
