I see a similarity in your question to this one: http://sketchucation.com/forums/viewtopic.php?f=15&t=51195. Within days of each other. I don't know if an answer is here or not.

My problem is not with Hardware Acceleration, but is Sketchup that is not recognizing my modifications in NVIDIA Control Panel. I have been having this problem with two of my laptops.
Thanks for the Reply

This might be an old problem.
I am using Sketchup Pro 8 on Windows 8, The display card is NVIDIA GeForce GT540M.
I changed the 3D setting in NVIDIA Control Panel, Sketchup doesn't appear to recognize the change. Am I missing any steps?
