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

I'm sorry for the folks experiencing this problem, but I have just tried to reproduce it on my PC workstation, and I find I cannot.

My system happens to be of similar power to the one described at the top but it is not a Mac - it's a 2007 design Dell Precision T5400 running Windows 7 x64, 8 cores, 16 GB, SSD storage, ATI Radeon HD 5670 1GB card.

I just opened a 9909 x 6501 pixel astroimage I happen to have on hand with over 40 layers. It's a mosaic of Hubble images.

• Display update when I move a curve on an adjustment layer is immediate while I'm moving the point on the curve, whether a global adjustment layer or one clipped to a layer below.

• Panning works smoothly. Even the flick panning nicely slowed down and settled pleasingly when I let up the mouse button.

• I can move layers and groups around perfectly interactively.

I just duplicated almost all the layers, so that now I have 81 layers.

• I see no difference in performance. It's still perfectly interactive.

• I saved the file with the extra layers and it's a 5 GB PSB file. The save took 21 seconds to complete.

Layer thumbnails are on, and all the while during testing I have been playing an internet radio station (without any skips) and I have a bunch of other apps open.

Is this a Mac-specific problem?

I'm currently downloading the big zip file posted above to give it a try. I'll report back when I do.

If updating the display is that slow, then most likely you're looking at a video driver problem. But we've also seen conflicts with Norton security, and some web browsers with some versions of Flash installed.

If you've applied those workarounds, then you have some other problem that we need your help identifying. No, there is no easy to see problem - or we would have identified it by now.

If you want a refund, call Customer Support.
If you want to see the problem fixed - work with us. Be specific about what the problem is, when it appears, what sort of document it takes to make it happen, what else is happening on your system, and what sort of troubleshooting you've already done.

Yes, and the 2 issues are related at a very low level - but they don't show up until you have a LOT of layers and certain preference settings. So they were missed in testing (and not easy to identify here because of over-generalization of the problems).

We've acknowledged the problems, and are working on them.

I have also tried all the fixes above AND on a brand spanking new iMac (3 weeks old) that is maxed out for RAM and is installed on a Solid State drive and as soon as I get to working with larger files for a concerted time it becomes unusable.

Just put 'Photoshop CS6 slow' in Google and it's easy to see the problem. I would imagine the guys at Adobe will have been instructed certainly never to admit there is a problem. With the power of social media they will certainly be very keen to quell any and all disquiet.

Not good enough Adobe. Currently I want my £900 back!

I had already read all the posts, tried all the fixes but so far nothing works. I don't have more time to troubleshoot so my fix is CS5 - it's a night and day difference.

The symptoms are also too great to spend time explaining.. everything is just SLOW. Like turning off a simple layer, takes 10 seconds for the scene to update. When I paintbrush, there is almost a 1 second lag, makes it unusable.

I've been using photoshop since there was only 1 undo, I have never noticed any sort of decrease in performance until now.

System:

Windows 7

Intel i7 processor

GMA HD 3000 onboard video (updated driver, same problems)

I also have the same problem on an i5 desktop with windows 7, and an 8800 geforce card.

And my i3 laptop.

Doesn't it mean something to you guys at Adobe if it all works well with cs5 but most certainly not with cs6 on the very same system - call up cs5 and it is excellent - call up cs6 and .................. !
This should give you something to work on?

Please read the previous posts in this topic. This is not a common problem.

And you need to be a lot more specific about your document setup and operations that are slow so we can figure out what sort of slowdown you are actually experiencing, then see if we can reproduce it. And make sure you've used the known workarounds to avoid the few known problems.

Also, your CAPS LOCK key appears to be stuck.

I MEAN JC, EVEN THE PAINT BRUSH LAGS LIKE CRAZY

I HAVE A BRAND NEW i7 WITH ALL TOP SPECS

I HAVE AN i5 WITH TOP SPECS

I ALSO HAVE AN i3 WITH OK SPECS

PHOTOSHOP CS6 WITH LARGE FILES (PROFESSIONAL ONES) RUN

E X T R E M E L Y S L O W & B U G G Y - ON ALL 3 MACHINES

PLEASE FIX, THIS IS A VERY COMMON PROBLEM FOR THOSE WHO WORK WITH LARGE FILES. MOST PEOPLE DO NOT, BUT FOR HIGH END PRO USERS - WE HAVE TAKEN THE BACK SEAT!!!
