It first began in the levels were you are first exposed to the tanks. After that, it would consistently crash as soon as I see the first enemy tower. About 50 attempts later, I finally got past that section but the crashes came again at random moments. What is with this game? I'm on Windows SP3, DX9.1 June 2008, nVidia 175.16 drivers, everything is updated and smooth, stock CPU/GPU....I get the "Mass Effect has experienced an unexpected error" blah blah blah related to the module "physx.dll" of some sort
