Alright just lowered my resolution and graphics. Still froze my pc, I don't think its a graphical error because I was playing before with a smooth 50fps, no problems. I don't know if this information helps but I was jamming to some music this time and the song was still playing for about 2 min after the freeze.
So my pc freezes about 10-40 min after launching the game. This has happened in the past and I was told to pick the play naval action in x86. After the first big patch It now happens again. Don't know if my game actually crashes because my computer freezes. But I did send a crash report(NAS-202973).
