I live in SoCal (Los Angeles), have TWC, and experience delays in my game which make Titan hardmode annoying because landslides and plumes can be hit or miss. I was googling ways to fix it and some suggested battleping and pingzapper, but I really didn't want to pay anything extra. So, I fiddled with the system configuration - graphic settings. It was set to Maximum or High/Desktop. I changed it to Standard/Desktop, and it made a HUGE difference for me. The game is actually playable! Hopefully, this helps some of you guys too.
