GT 330M issue?

Hi Guys,

I have one of the last generation 15" i7 mbps and have suddnely realised that the intel integrated graphics card seems to be outperforming my discrete one?

It's especially noticable when using spaces as when going between itunes and safari it's super speedy, but add an application that starts up the 330M (such as iphoto) and the switch between the two same spaces with just itunes and safari suddenly becomes all laggy.

Is this a know thing that the 330M is slower off the mark or is this an issue that I should take to apple?

Many Thanks

ok then

so what should i do about it? just leave it as i use the integrated so much more or actually bother to go to apple about it?

just to make things better my integrated graphics seem to have decided to have it's time too:

yes apparently that's a screenshot of my screen

i'd love to be able to agree but unfortunately it isn't that

it flickers when i start iphoto indicating the switch and profiler shows the 330M becoming the one driving the display, and i've made sure everything's minimally using the card and it still manages to lag doing what the integrated can just zoom through
