Exposé Slowing Down/Choppy

I dunno maybe im hallucinating but yesterday's update seem to remedy the situation for me.

would that explain why on expose slows when mbp is running solely off of battery power?

A corrupt driver will render everything useless,,,not dependent on battery supply.

My take is that since MBP has dedicated GPU, the SpeedStep technology also churns down the speed of the GPU and CPU when on battery power...

That would make most sense to me ....

I wish there's a tool out there I can use to check my GPU clockspeed...
 
Now that I notice this topic is still alive i want to add that i have had no problems with expose, far from. Even when I have a HD movie on in quicktime and several other things it stays as smooth as always. Maybe you should solve it the windows way: with a reinstall. (hey I just switched last week ;-) )
 
I have the problem on my new MBP. The security update does not fix the issue. If anyone is successful in finding a solution, please post it here.

Thanks

Hi guys,

I am having this problem:

My expose runs choppy (a bit) when my machine runs on battery power (even fully charged and in best performance mode). It runs really smoothly though when it's plugged to a power supply.

I am not running any mem hogging program at the time....

Does anyone has the same problem with their Core 2 Duo Macbook Pro (mine's the 2.33Ghz , 2 GIG RAM model...)

I notice some choppiness in battery mode as well. I have the 2.16 GHz.
Sometimes I get lag trying to change the wireless airport connection.

i know what you mean - there always seems to be a delay when I click on the airport icon in the menu bar....i think this may be "normal"....I am more worried about the expose - still no fix i guess...haven't had time to go to apple yet, but I have a feeling they would laugh at me anyway

Actually, much worse now - go to PREFERENCES » SECURITY and my PREFS crash. Reboot does nothing. I can't put a password on my comp when it goes to sleep and reactivates ... sad sad sad.

THanks for the tip - I actually tried 2 reinstalls early on when I originally noticed this issue...unfortunately, nothing. So, for you, there is absolutely no difference at all when you use expose running on battery as opposed to running on ac power? Interesting! I they were all choppy on battery power, it would be much easier to swallow - however when there are some MBPs that run beautifully and others that hit the brakes on battery power - makes me want to get it checked out. thanks for your post
 
Any updates to this issue? Expose and Dashboard are super laggy/choppy when I'm running on battery power. As soon as I plug it to the adapter, it operates smoothly. I know it has nothing to do with the video card, as macbooks don't suffer from the issue.

:mad:
 
*BUMP*

I made a new discovery. Tonight I played a video from the Apple quicktime gallery and while playing the clip, i opened up a few windows and activated expose. It worked flawless and so did dashboard! (on battery power)

Now I know the issue has to do with the video card. Now we need to find a fix.

Can someone else who was having this problem try this? :)
