I run dx9 so i don't have the freeze and crash issue, but i do some pretty impressive performance issues. I get up to and above 150fps right up until i get near a base firing ack (friendly or enemy)... the bigger the base the lower the frame... I hit 7fps today. I first thought it was the number of players in the area OR when i was near the ground and the detail was causing it, but it happens when the ack fires with just 2 players or 20 and with the graphics settings all down and off... I have a feeling it is my old phenom II, i know many newer games have issues with that CPU that have to be patched but i thought Id throw it our there to see if anyone's got any ideas or has had the same problem...
