    They came out a few days ago. But I've noticed that the ATI overdrive is quite a bit different. The 10.2 drivers allowed the GPU to automatically step down to 600MHz from 750MHz, when idle. The memory could be run as low as 450MHz (though it had to be switch manually), and the gauge would report ice cold temperatures at idle. This is a 4870 I'm talking about, and underclocking the ram was almost like turning the card into a 4850 at the flick of a switch. Great for when you're not using the video card much. And some games will obviously run at 60fps with the memory underclocked like that anyway. It was pretty cool, even though you had to switch it manually.

    Anyway, I notice in the 10.3 catalyst, that the GPU won't go lower than 750MHz, even at idle (even though you can set the slider as low as 600MHz). And the Memory is the same, in that it won't go any lower than 900MHz.

    Anyone else noticed this at all?
