ok guys I only know so much about these nvidia graphics cards so bear with me....
Spec - HP pavilion DV6552ea, windows vista home premium 32bit, AMD turion X2 1.9Ghz, 2Gb ram, Geforce 7150M / nForce 630M (shared memory of 128mb) 425Mhz
ok aero/3d flip is sluggish, when nothing is running on the desktop. I can't even scroll through internet pages smoothly. When I'm playing a dvd or running a media player with complex visualizations I find it runs fine. Strange i thought at first since this should be the other way round if anything.
After some research I found its the power saving feature on this card reduces the speed of the GPU to 100Mhz which isn't enough to handle the aero theme. Obviously when complex graphics appear on the screen it either speeds up to 250Mhz or to full power at 425Mhz and the problem goes away. Problem is this feature doesn't seem to react to flip3d or complex scroll and the laptop struggles along.
I've tried using overclocking programs (eg ntune) to set this to 425Mhz constantly but the power saving features kick in and reduce it back down to 100Mhz.
I can't run any other drivers than the ones provided by HP (not even ones from nvidias website) since it brings up an error saying something about them not being compatible and recommend I get them from the laptop manufacturer.
I've also tried a few unofficial laptop drivers (laptopvideo2go for example) but they bring up a BSOD on reboot.
the problem also decribed here by someone else if my explaination is crap -
