This might be a stupid question, but you HAVE updated ATI drivers on your system right?

Appologies for not posting a new topic

I normally experience a slowdown during the time compression on the navigation map. Normally when i try to push higher than x2048 certainly the x8k + is like pressing pause. I'm unsure if this is a graphical issue, however the stopwatch appears so hence linking this query. Graphics wise i'm running a nvidia 8800gts, 2.1(core 2 duo), 8gb ram, vista-64.
I had simular probs on XP-32 with only 2gb of ram so presume its something to do with the game? (note i had simular issues with the time compression in SH3)

On a side note are there any mods (or settings) that get rid of the stupid amounts of algae thats in the sea?
