Bioshock on Windows 7 64-bit insane loading times (45+ Seconds)

[fromcat2me]

Hi,

I updated my box to windows 7, 64 bit, radeon 6670, 16g ram, trying to play bioshock 1 (d/l through games for windows marketplace). version 1.1. For whatever reason if I start a new game, go down the first elevator (first save point), quit and restart from there, the loading to load the level takes over 45 seconds (this then happens whenever any new level loads). I've tried all the compatibility settings, the affinity settings that the mass effect people are using (i assume this might be an unreal engine bug). any ideas?

I've got your OS, a Radeon 6870, and 8 GB of RAM (it's only 1330 or somewhere around that). My loading times are 5-10 seconds, so I'm not sure what your problem is.
