PPro CS5.5 Timeline Lagging on MacPro

[Tim Kolb]

I’m on Windows…has there been any problem with QTX on Macs with Adobe? Have you tried to roll that back?

If you can’t seem to get any progress I would suggest installing OSX on an old hard drive with CS5.5 and trying that. It’s possible to get something wanky with the OS that’s impossible to sort out. At least you can verify if it works normally on your computer that way by eliminating the variables that numerous software installs could have introduced.

Thanks Tim for the suggestion, not as yet. Interesting, I will give it a go and see how it works out.

Robert, I’m trying to leave that as a last solution thing but I think it might come to that.

I’m surprised no one else here has had the same problem as there are quite a few users experiencing the same thing on the Adobe PPro forum.

There is a particular update on the SOFTWARE UPDATE of Apple. That basically makes the NVIDIA playback engine and Ppro to perform erratically.

I believe this latest software update made that. I read it on the NVIDA forums that they are working on a fix for that. When i find the link, i will send it here

[Alex Hawkins] “Thanks Jon for your suggestion but I have all the latest drivers etc.”

Aah, I think Robert might have the answer there… are you on OSX 10.6.8?
I dont have any lag and I am on 10.6.7.

I’ve always had the laggy clip drag issue you’ve mentioned, in Mac OS 10.6.8 and Mac Pro 2008 8 core with 24GB and Quadro 4000 card. Happened in CS 5 and 5.5. I think this is a pretty common issue. I’m going to try it with my newer Macbook Pro. it seems to get slower as the project gets larger and more complex. We really need to resolve this!

Hey Alex, You didn’t specify what is your complete specs on the post. Anyway, there is a driver issue when you upgrade your Mac into 10.6.7

You can read more about it at this link

Here is a portion of that url

Heads-up – the OSX 10.6.7 update contains bad graphics drivers for the nVidia Quadro 4000 GPU. After using either Software Update or the Combo Updater, Quadro 4000 users will find that they’re no longer able to use the 2nd display output on the card, screen capture, or record video directly from the screen, plus there appear to be performance problems and ‘tearing’ when scrolling up/down.

More of the Apple updates killing the CUDA

Well folks, I hate to say it looks like the Apple 10.6.8 broke
the nVidia 4000 for the Mac card support of GPU acceleration in Premiere.

And lastly this can also be seen on other Creative Cow threads

This is one classic advantage of Apple being the manufacturer of the hardware and developer of the software. And in exchange, third party developers are always left behind.

Thanks for the driver info.

It’s normal procedure for an Apple OS Update to break NVidia’s Cuda and driver support and then for us to have to download new drivers from Nvidia, it’s caught me several times.

However that’s not what is responsible for the problems the Mac users are seeing with this ‘lagging’ problem. Maybe it’s just a fact of life (at least for me) with Premiere Pro but it’s sluggish, especially when your project gets complex.

That being said it’s still the best NLE option for the Mac out there. It’s now either PPro or Avid.

However I feel that if Adobe has the resources they could improve the Mac product. Could somebody post a screen recording of their Mac or Windows that doesn’t ‘lag’ like we are all seeing, thanks much.

[Alex Hawkins]

Thanks Dexter for all the info. I have been through all these issues with the driver and updating from 10.6.7 to 10.6.8 but this was a problem before this. Plus I have a GTX285 not a Quadro 4000.

The whole thing seems to me to be some sort of memory or caching issue, as like Keith said, it gets worse the bigger your project gets.

I have a thread going on the Adobe forum as well but no real answers yet. I think at the moment it might be just a fact of life with some MacPros. Don’t ask me why.

In essence, it’s a bug and Adobe now knows about it. Just shrink the vertical height of your timeline for now and things will speed up.

Hope this helps!
