Hello,
Thank you for providing all the details and the files that you did, those help significantly when trying to get to the bottom of an issue.
I've taken a look at the image you provided and have opened the .pp2 file, and nothing within either of those signifies any type of problem that I can tell.
There are a couple of things that you can do that might help us track down the root cause:
-Tracing to the game(s) servers that you are having a problem with (if you're not having problems with google, then tracing to google does not usually provide valuable insight)
-Tracing to the server(s) for long periods of time, rather than just when you're experiencing the problems
I'd suggest leaving PingPlotter running and tracing to the server(s) that you're having problems with, then if you're able to capture the issue occurring on that server, we *should* be able to take a look and get an idea of where things are going awry.
We do have a guide that gives several tips and tricks of how you can use PingPlotter to pinpoint where the problems are occurring, and also what you can do with that information to better your case. I'd recommend giving that a read and seeing if that can be of help:
