I am at verge of reverting back to Snow Leopard. I have a MBP 13 inch 2010 model with Nvidia 320M graphics. The main thing keeping frustrated with Lion is it's choppy animations, scrolling (in Safari, Mail, pages flips in iCal, Preview...). For example, in mail there is a lot of flicker in text when scrolling. Emails with image/pdf attachments are super choppy. Even little things like system preferences transitions are cheap looking. And this is after clean installing 10.7.2. It seems that these problems might be caused due to poor quality/ defective Nvidia 320M drivers (notice other MBP 15 users are having problems as well on their Nvidia 330M). Doing extensive research, I still can't find if Apple is actually addressing these issues in the upcoming 10.7.3. Are there any updated drivers for these graphic cards in 10.7.3? I know I might sound obsessive for smooth animations, scrolling, smooth everything.... quality animations in OS X Lion is suppose to be one of the main ideas that bridges OS X with iOS as Apple intended them to be. Just look at your iPad and iPhone, see when you do something, not even a single time there is a hiccup in any animation/moving text. If they want Lion users to have an iOS feel, they really have to address this. I have tried many times sending feedback to Apple (since 10.7.0, didn't seems to work at all) Note: I tried to recreate all these issues with the latest i7 MBP and most of these issues actually don't appear. This further makes me think that it's happening because of bad graphic drivers in the 2010 MBP. In Snow Leopard everything was smooth. Also, anyone who is kindly willing to discuss, does 10.7.3 introduce new little customizable feature such as ZOOMING EMAIL MESSAGE using pinch, and using two finger swipes in finder and other apps? Thanks! I really appreciate your responses.
