Logic 9.1.5 using more CPU in 64 bit...

Post by Guest » Wed Jan 11, 2012 1:19 pm

Yesterday updated to Logic 9.1.5

 

Have opened up projects in both 32 bit and 64 bit mode (but only 32 bit kernel as my mac pro is too old for 64 bit kernel).

 

Projects in 64 bit mode spike the CPU meter, and result in clicks and pops during playing.

 

Quit Logic, change to 32 bit mode, reopen same project. CPU meter reading lower, no clicks and pops on playback.

 

Now its an older machine (Mac Pro 1,1) and I am also running Vienna Ensemble Pro with a 9 GB template loaded up, but not connected to these projects I am opening, naturally this is taking resources.

 

Anyone else notice similar results, that the 64 bit mode causes projects to use more CPU?

In 64bit mode, are you using any 32bit 3rd party plugins within these projects? The 32bit bridge might be taking a hit on the cpu. From my experience, Logic in 64bit mode with 64 bit plugins has slighly less cpu usage than 32 bit mode. You may want to try a project with only Logic plugins in both modes for a true comparison on your machine.
