Has this been fixed since then?  

 

This is a good question, because I was using CS5 and obviou= sly there have been some major changes since.  I haven't dug through t= he archives to find the original thread, but the jist of what I can remember is that when After Effects uses a Photoshop file, i= t loads up the actual Photoshop library (i.e. the Photoshop rendering engin= e) but can't control how it uses memory.  Unfortunately the Photoshop = library isn't very memory efficient, so if you have large Photoshop files and are on a machine with limited ram= - e.g. 12 gig or less - then the computer starts to use virtual memory and= everything grinds to a halt.  It was a problem I had originally blame= d on a poor network, but I realised the problem was exactly the same on Mac and Windows, and at every office I wor= ked at.  Sometimes everything would freeze for over 5 minutes and a no= rmal person would think the thing had crashed, but it would eventually star= t working again.  I was stoked when Todd explained the problem and the solution (don't use Photoshop files).

 

I don't want to hijack the thread with this separate issue,= but once I inherited an After Effects project that took 45 minutes PER FRA= ME to render, using Photoshop files.  I cleaned it up and converted the PSD to tiff layers and got the render time down to= about 20 seconds per frame.  I actually started to write an article o= n it because I thought it was a curious case, but then I realised I was jus= t writing pages of stuff that was basically bitching and moaning about my co-worker so I let it go…

 

Since then it is more common to find larger amounts of ram = in a machine and there have been major upgrades with CS6 and CC, so I'd be = interested to hear Todd's input on this matter.
