I am now getting the same problem. It varies when it will happen, but it is always 30minutes into a game.
I am running the game at highest quality, in windowed and fullscreen, in 1920x1080 resolution (native). all my drivers are up to date. I get no minidump.
the exact message that i receive is "Sins has stopped working" and i have the option of "checking for a sloution online" or "closing the program"
My system specs are:
core [email protected] x 4
GTX 275
8GB ram
I may be able to provide more information if required.
