Just bought the game via Steam and got two CTDs in the first ten minutes of playing.
1. When clicking "Continue" in the menu (after readjusting graphics settings, saving during the tutorial/first campaign and restarting).
2. When issuing a move command (map view/zoomed out).
I can provide a dmp file for each CTD as well as a system summary (via DxDiag) and the Settings.xml used. Just point me to an email or something where you would like to have those sent to.
It might be a good idea to put up a "known issues" thread/sticky here for quick reference if there isn't one already which I might have missed :)
I am using an ATI graphics card on Win 7 x64, drivers should be up to date. Things I changed in the settings: Turned on Antialiasing (8x), set Vegetation Detail and Texture Filtering to "Highest".
