The IPs seem to be stored in an encrypted file. Actually, the .nds files seem to be common in the Atlantica folders, so I'm leaning heavily toward the idea of an encrypted file (possibly also capable of archiving multiple files in one, and then encrypting them all).
In any case, the lag mysteriously disappeared now... :/
And no, I don't have dual monitors with my laptop. The desktop in the basement running XP that my brother seems to think he owns now has dual monitors. And I went over th Gamedev.net and asked them in their D3D section, and they linked me to a thing about hooking the D3D routines and inserting my own code in via DLL injection. Unfortunately, all the code is in C++, and I have not worked in C++ in way too long. I was hoping for it to be possible in C#, but seeing as how encapsulated C# is in some ways, I severely doubt it would work without even more work.
Also, if I write my own program after all, I won't use the ping /t command, because I want more control over my pinging. I'll earn what is necessary to actually do my own ping command.
