C2C run better on xp then on 7\8
i done some testing on memory usage with some last svn rev (3 days ago downloaded)
on win 7 game got 2 first chance exceptions
[10.02.2013 6:48:12] C:\Windows\system32\avrt.dll loaded at 0x74700000

[10.02.2013 6:48:12] First chance exception - 0x406d1388 caused by thread with System ID: 1740
and one then you start new game generation
[10.02.2013 6:52:28] First chance exception - 0xc0000005 caused by thread with System ID: 1740
that resulted with fatal exception 0xc0000005 from cvplot+1 ast stated by debugdiag
on XP i dont have crashes at all and no these exceotions too.
for memory :
on win 7 - started game grow to 2750-2900 mb (virtual bytes) \ 1300-1600(private bytes)
on XP - 2000-2200 (virtual) \ 900-1100 (private)
so if you playing from xp you can play MORE complicated game then on win 7
as civ4 engine 32-bit application what dont know anything about AWE - more then 4000 mb ram dont do any good for it
p.s. sorry if this info not needed...
