9.1.6 CPU spiking when scrolling in arrange

[Janne]

Hey guys

 

Im experiencing Cpu overloads when scrolling in arrange window in 9.1.6. Only one of my 8 cores is overloading(no mater what io buffer and processing buffer is selected, and also number of cores).

 

Im on Lion 10.7.2 on a quad i7 MBP. Any body else getting this behavior? Ive tried some testing and didn't find any solution:

 

-repairing permissions

-using Onyx for all system maintenance

-turning graphics card switching on discrete only

and finally making a clean install of Lion and Logic

No luck

 

If I look in the Activity Monitor the cpu percent for Logic jumps drastically .

 

Its for the first time since Logic 7 that Ive found myself in a corner without a solution :/

Weird. You're just scrolling, not during playback? It sounds like it could be an issue with your graphic card. Do you have any other issues with your MBP not related to Logic? Does the CPU also take a huge hit when you watch a video online for example?

Hey David thanks for the response.

 

The cpu hits occur with or without playback. Its really weird. I don't see any other software having similar issues.

I have 2 graphic cards in my MBP(Intel integrated and Radeon 5750) and they both do the same. The most strange thing is that i see spikes in Logic itself and also in Activity monitor(In Logics threads).

 

I didnt have any such issues with 9.1.5.

So the radical move will be to move back-fortunatelly i have a backup of the update file, but the new multicore bounce is really nice.

 

Ive reported this to Apple via their feedback system.

I've just been through Apples support forums and it seems that I'm not the only one with this issue:

 

Logic 9.1.6 scrolling causes CPU overload
