Any workaround solution for lagging cursor on ML?

Hey guys,

Im running ML 10.8.2 on my macbook pro 17 inch. when the machine runs on intel graphics there is a significant cursor lag especially when panning over pdf on safari and not in preview, and also when you have a long list of typed out items and when the cursor tries to change from its usual pointer to the 'I' shape. (the problem is not present when using the integrated graphics chipset - nvidia)

From doing some research i've found that this problem is faced by a lot of people. If anyone has found a temporary solution for this matter can you please share your tip?
