At the start of the demo, when you are submerged, just after you see the pear necklace and start to rise to the surface, I get these weid black squares on the screen, that dissapear when you get to the surface.

Anybody else getting this problem, or is it just me?

My specs are;

Intel E6700
2x Geforce 8800 GTX
Xfi Fatal1ty Sound Card
2 GB RAM
Win XP SP2

Using the new beta NVIDIA drivers and I am also using RivaTuner to increase the fan speed of the graphics cards
