In general tickrate does not equate with fps. I recommend for your box set tickrate at 66 and unlock framerate 'fps_max 0'. Then tweak your rates accordingly. If you want experiment the effects of a single framerate try i.e. 'host_framerate 100'. //Set to lock per-frame time elapse. Must not to exceed servers ability to render frames. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
