This is really encouraging. I have Vista 32-bit, but it came pre-installed on my PC so I am not sure there is a way to change it to 64-bit without any CD's.
Been playing now for the last couple of days, not a single CTD using both texture ESMs where as before I CTD'd within 60 seconds. So it's definatley the extra 1gb recognized by Windows or something else about the 64-bit O/S that solves the CTD problem.
