@chaton, I live on the East Coast and have Sandstorm set to connect to US East servers only.
My ping should be at the top left of the video as part of the debug overlay. In the clip, it ranges from 33-41ms during play, then skips to 69-79ms during the first-person death animation at the end. If it would help, I think I still have the video of the whole game and can give you a broader average ping over the course of the match. If you want that, let me know.
Thanks as always for the response!
