I just noticed that Xbench gave me a better OpenGL score on my new late 2008 MacBook compared to 10.5.5, so I was wondering if anybody knows how much better the graphics performance actually is in 10.5.6? Although I just traded in my old white MacBook with a crappy intel graphics card for the new MacBook with a rockin' graphics card, I am curious how much the 10.5.6 update improves performance on the intel graphics cards. Anybody know? can anybody compare the OpenGL results from 10.5.5 and 10.5.6 to see if I'm the only one who is seeing an improvement. Did Apple update the graphics card drivers or is there some other reason I'm seeing better performance?
