Hi Tango,
Looking at the machine specs, Crash Dive should certainly have no trouble running on your hardware. But from what you're describing, I suspect that your graphics chip isn't able to run the fancy water shader I use in the PC version of the game.
Unfortunately, there's not much I can do to fix that, but as long as you bought the game in the last two weeks, you can go to
