P: CS6 Slow compared to CS5.1 with large files

PS CS6 has a lot of enhancements and great features. it launches very fast, and the control is very responsive and smooth.

although i am experiencing some speed issues with very large files. compared to CS5.1, where i don't have any of these issues.

the files are PSBs, 9000x8000px, 80+layers, RGB, 8bit

i have the same performance settings for both, cs6 and cs5
i am working on MAC PRO, 16GB ram, SSD scratch, 2TB raid, Radeon HD 5770, Snow Leopard.

the main issues i have are:

- no refresh when i move the curve on adjustment layer. the refresh comes after i let go.
- jagged pan
- extremely slow moving of layers and layer groups, even if they are with smaller dimensions (800x400pix)

again, working with files with less layers or smaller dimensions is very fast.

thanks for your help and support!
m.

    I am experiencing major problems with the speed of Photoshop CS6 with larger files.

    I am running it on a brand new (2 weeks old) maxed out iMac (16GB RAM off a solid state drive / 3.4 GHz Quad Core).

    I work with files of between 200—700mb (layered). I purchased the new machine and CS6 as CS3 was starting to run slowly on the old iMac. Having parted with the best part of £3.5k I am back where I started!

    Please can Adobe respond and let me know what is being done about this, it's driving me up the wall!

    Finally had a chance to get back to this problem, installed a new HD from scratch, nothing else on the HD, installed CS6 Photoshop and had exactly the same issues as before.

    Tried everything in this thread that was suggested, nothing worked, until...

    Setting Cache Level to 2 fixed pretty much everything, no weird zooming behaviour or any of the glitches and beachballing that happend before.

    So, looks like that can be a fix - to be honest I've never touched cacheing before on any install of Photoshop and I've been using it since version 2.5 (20 years, wow!) but there you go.

    P.S. gotta agree with Sean above, the employee responses on this thread have been very poor indeed - this is an official pro-software support forum, not YouTube comments.

    I'm experiencing same issues as described above.

    Awaiting a fix.

    And I gotta say... the employee responses on this thread are a bit unprofessional. There is usually a specific process to responding to a support inquiry in which exact questions and answers are dialogued. There is a lot of "You assume..." and "Well, most users don't see this issue..." going on which doesn't help anyone.

    My advice is to remain transparent, do not engage socially or try to level personally with us - almost canned responses are better at this point when you have very agitated users.

    OK, I need to get a copy of that file so we can try to reproduce that slowdown. That could be video driver related, or could be something internal to Photoshop. I won't know until I can reproduce it and profile it.

    Well, the thumbnails changed in CS6 (known problem), but the effects didn't.

    Vector shapes got more options, but should be the same speed or faster than they were before if you use the same old options. If you add a vector stroke, then it will be slower because it now has more work to do (equivalent to another vector layer).

    Definitely looks like the same issue. I have to say lowering the Cache levels to 2 has really helped. Before that, the opening of and moving of layers on larger, more layer-rich files was painfully slow. Like full minutes (2-3) to open and 10-15 seconds to move a layer group like 10 px.

    That link is an example of the delays that I am still experiencing, even after changing the cache levels to 2 (vs 4) and turning off layer previews. Its a lot better for me in the above video with those two settings changed, but it could be better.

    Alex, can you tell me if this is the same type of thing you are experiencing?

    Thanks Alex, but I can't take credit, it was that guy above who noted it. It just worked for me to some degree too.

    I still have one or two specific files that I could video with my phone and upload to Youtube or something and post for Chris's review, he'll see what we mean in action. I don't beleive anyone has done that yet.

    I think it will become abundantly more clear what we mean if he can see exactly what is happening

    Allan has a great point that I consider a bit of a breakthrough (other than layer thumbnails) in making CS6 a little faster. I changed my cache levels to 2, re-started and did find it quite a bit faster. Not quite CS 4 or 5 fast, but closer and more useable with large, multi-layered files.
