So far I haven't experience as much lag with it now compared to it being first coming out.
I haven't noticed anything, though my computer is to blame for that. Bad specs all around and the phlog demolishes this thing. I have one of my own, but I seldom use it because I don't know what's going on when I use it, for the most part.
how do I get these aformentioned fonts?
You can just change the locale on your computer so it recognizes Japanese. (assuming Win7: Control Panel, Clock Language and Region, Region and Language, Administrative tab, Change System Locale) You'll have to reboot. The fonts are already built in with most OS's, you just have to tell it that you're using them, because by default, Japanese will read other characters since that's what their equivalences are in English or some other language. Hence, why EoSD for vsync is weird because 東方紅魔郷 =
