I've been a member here since 2008 and this is my first post lol
I just ran into the typical performance issues as soon as my city hit 150k population tonight. I am so livid! Searched these forums and Google for hours, tried everything under the sun but my lag issues won't quit. I've had my retail version of SimCity 4 Deluxe since 2003 and only now have i ever run into issues on my two machines (Windows 7 and 8.1, both x64 architecture). Both have AMD Radeon graphics cards.
This really sucks man, just venting. I may pick up SC5 from Origin since it's on Flash Sale. Just venting, sorry
