I bought this in the steam summer sale(ultimate edition), finally got around to booting it up.

It plays fine inside with doc, but when I go outside it takes about 30-60 seconds before I CTD with no error message, just straight up boot to desktop.

Win XP SP2.
Core2duo 2.4ghz.
4GB ram (yeah I know I can't use more than 3.3)-
Geforce 8800GTS 320mb.

I know my computer is aged, but it should handle this game...

I run it with all the DLC activated.
