Woohoo! I was able to get SH3 with Grey Wolf expansion running on my Toshiba laptop Win7 64bit 8gb ram without a hitch. Did a test with full graphics, seemed no problem but did take sometime for the simulation to load.
Goodness this looks like a complex game going to need a while to read the manual and figure out how to operate my boat.
ooops used google's translator was trying to say my boat was afloat
