Hello,
This question doesn't specifically relate to screen grain, but it does concern the display generally.
I was wondering if anyone had noticed screen tearing on the MBP C2D during high GPU intensive tasks. The reason I ask: I currently have an HP nw8240 which has an ATI FireGL V5000 (128MB) graphics card. This is a fairly high spec machine, but I have noticed that certain grahpics tasks cause screen tearing (specifically, OpenGL screensavers and some fast moving DVD scences). The effect you see with tearing is like a horizontal line moving up and down the screen. The reason this happens is when the frame rate is higher than the screen refresh rate. The normal fix is to enable vsync with the card, but this has not worked in my case.
I'm wanting to make sure the Apple doesn't suffer this same issue, being as it also uses an ATI card. This does not happen on my work notebook, which uses a much lower spec Nvidia card.
If anyone is willing to test this

D ) i'd be very greatful. A screensaver that consistently tears on my HP is called Hyperspace (if you Google it, should be easy enough to find, plus you'll get a lovely saver!).
Hope this isn't too much trouble.
