2xAA and 2xAF still only using 980-1gb ram. the game is likely reserving a small amount of the GPU memory space.
performance wasn't any better or worse with these settings enabled/disabled. also, performance from medium to ultra didnt change for me either.
again, this points to a cpu bottlneck not a gpu bottleneck.
my system is:
c2d e7200 @ 3.2ghz
4gb ddr2 @ 1066mhz
gtx460se @ 850mhz core/1700mhz shader 1990mhz ram clock
gives me about 10fps average low over london with ultra settings except seizure filter, grass, shadows, and roads unchecked with irror disabled.
again ram utilization hovers between 980-1010.
