Ok, just got the game from Amazon. Once loaded it immediately began downloading patches. Looks like it is 1.2 now.
Unless I am missing something, my p4 3.4 ghz runs this game great! I went into graphic settings once the game was installed and the graphics were already on maximum settings. I have a new Radeon 6570 1gig video card. I can walk all over the sub without a "shutter" at all.
By the way, does SH5 have torpedo or training missions? I am lost right now
