What did the graphics update do for MB ?

[Sceneshifter]

Hey guys,

Like someone else posted on iMac forum I too was amazed, after patching 5.2 I rebooted this morning and hoopla there was apparently another patch! My stacks grid thing sure is working faster, but I'm quite sure that has little to do with that. However, I am very much wondering, did they update the X3100 drivers for the best? Or is there no difference in performance?

Thanks!
