i installed ME2 on my new computer (plays ME3 on high settings no problem) and the game is very slow.  my character runs slow... everything seems like its about 1/2 speed.  i installed the patch 1.02 and it is the same.  i turned off all video options, and it is the same.  i fired up my old computer to see if i was just crazy - and it plays normally on that one. 

my pc is a core I7 950, 12gb ram with a gtx 580 video card... it plays all the new games just fine... but for some reason ME2 is slow...

any suggestions?
