they found a way to fix it today by renaming pso2.exe to pso2launcher.exe (change old launcher name to whatever)
this bypasses the launcher so you wont be able to update, but it magically fixes all lobby lag.
as for the game not wanting to minimize, try have a background app/window to alt tab to, or ctrl+alt+tab
if that doesnt work u may need to try get this game in true fullscreen mode. \Documents\SEGA\PHANTASYSTARONLINE2_NA\user.pso2 open with notepad and scroll to bottom and set VirtualFullScreen = false with fullscreen to true.
edit: theres also the PSO2 tweaker which is working for NA now, if anyone has troubles getting to start the game or patch:
