The stock centos kernels do not have hrtimers, so you aren't able to get low latency sleeping. The 2.6.18 kernels are very good latency wise, so unless you want to patch them in you're going to have to build something newer. The newer kernels with CFS are pretty much crap, in my opinion, due to the scheduler changes and other .. things, but mostly you will need HPET support in the BIOS enabled with hrtimers. As Laws stated eariler, the older kernels are generally better overall, and newer kernels with RT have too much overhead in most of the codepath the game does not use. -M _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
