If your game has Steam multiplayer and you are using Presence on your listen servers, you probably know that Get Ping in MS is broken. It will always return 9999, regardless of firewall settings, ports forwarded, anything.
If you turn Presence off (like in the case of a dedicated server), Get Ping in MS suddenly works. But I’d very much like to keep Presence on so you can join friends in servers. Turning it off has some other issues too that I’ve found.
We’ve tried several other methods to get ping from the server browser, but none have worked properly. Tried Beacons, some custom C++ pinging, to no avail. At this point we need to hide ping from our search results and hope people don’t get too mad if they join a server with 200 ping without a warning.
This is a very common issue that has a lot of background on the web but nobody has been able to find a definite solution.
Here’s a few links:

Any help would be very appreciated. Thanks so much.
