  • large spikes after 30 minutes

    I made another thread regarding this and never got a reply back from anyone (looking @ valve guys d=) I seem to get really weird connection failures after 30 minutes at first I had believed this was an issue of playing on the EU servers but now that the NA servers are up I am still experiencing the problem, now I know my connection isnt that great to begin with but surprisingly its quite smooth with a 500+ consistent ping and it remains pretty smooth (of course with some delay) till around 30 minutes and then I start getting connection errors and extremely large spikes usually lasting till the end of the game.

    I have tried disconnecting waiting a moment and then reconnecting to see if it would resolve the problem but hasnt is there any way I can find more debug info regarding why this is occurring?

    When you're getting connection issues, do a "net_graph 5" in the console and take screenshots of the graph after a couple minutes.

          From the graph you are getting pings over over 600ms and several periods of excessive packet loss. Looks like the connection from you to the server in the screenshots had a lot of loss. The gaps in the net_graph are periods were you simply aren't receiving the packets from the server. Looks like these are lasting for several seconds.

          Where are you located? I see DerrickG in the screenshots and know he's a us player. EU Servers are back now. Do you see this kind of lag playing in a practice lobby by yourself? You can also select which server data center to play on when you make a practice lobby.

            I am playing from Northern BC Canada near the Alaskan boarder to be completely precise Terrace BC, my pings are extremely excessive because of that fact that I use a satellite connection, however, as I explained through the beginning of the game till around 30 minutes in my connection is perfectly fine and playable or at least in till the spikes occur I have also played several games where the spiking never occurs including several games in a row where it doesnt occur.

            I do have a hunch it has to do with a large group of packets that I am receiving all at once this may be due to large fight scenes but again I have had these in the past and not experienced the lag issue also some times the spikes occur when there is nothing going on at all.

            I am not a 100% sure on how to read the net_graph tbh is there a site that explains all the data you get from it, knowing this might help me track down the problem.

              I can't really fix satellite latency. The drops you are seeing are caused by contention and loss between you and the satellite link. On a long range link like that, you are competing for bandwidth by other users and the loss can be due to that contention as well as actual atmospheric issues causing signal loss.

              Basically, internet games that are UDP based this aren't going to be very playable on satellite links. Do you have other internet connection methods in your area available?

              I know BC well. I grew up in Merritt, BC actually. Not quite as north as Terrace, however.
