It might be the game itself that gets even more dodgy and weird at a 200 player limit.
And not the server specs. This still needs some testing though.
We know, that's the software improvements we're talking about (better multithreading).
DTV is buggered, AI only spawns a few mobs. Posted on IRC as well.
DTV is not running on the new server.
We know about the bug, should be fixed soon.
