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

This is the wrong topic to discuss Bridge issues -- if you have performance problems in Bridge, please create another topic.

Finally got all the pieces together to capture that video. I did it in a virtual machine, so it's not quite as efficient overall as on my host system, but the relative performance differences between Photoshop CS5 and CS6, and between thumbnails enabled and disabled are the same:

This was encoded in Windows 8, and for that reason doesn't seem to want to play in Windows 7's Media Player, but it will play in Quicktime.

We're not sure yet. We may just blacklist those driver versions and use simpler GPU settings for those GPUs and drivers. (because it may be a long time before Apple releases better driver)

Anyone else having this problem? I know laden m, who started this this thread mentioned having a similar problem, and he said he was on a mac pro. The pan is almost the same as cs5 on my macbook pro, but there are times when it is a little slower than cs5, which isn't the biggest deal on my more powerful computer but is a big deal on my Air.

Chris, is there any way this driver issue will be resolved in subsequent PS CS6 updates at all?

Nope, can't replicate the jagged pan at all. But we have seen some driver slowdowns with the Intel GPUs on MacOS (CS6 makes more demands, and the driver says it can do it, but can't really).

Also forgot to mention that applying free transforms to a layer/layer group is also slower in CS6.

I downloaded Ray's file and experienced the following:

There are speed improvements in CS6. However, there are also slowdowns.

Faster in CS6, slower in CS5:
* Opening the file (dramatic difference)
* Panning/Scrolling (subtle but palpable difference)

Faster in CS5, slower in CS6:
* Dragging a layer or group of layers
* Screen refresh/redraw when turning a layer/layer group on and off

I've optimized my CS6 settings as suggested in this thread, so the dragging around of layers and screen redraw when turning layers on/off are *tolerable* enough in CS6 that I can now spend the majority of my time in it, but they it certainly doesn't match up with CS5 performance in those two specific areas for me.

I'm on a MacBook Pro; have posted my full system info earlier above.

Any update and or response to the jagged pan some of us have been seeing? I commented a couple weeks ago about this issue.

Chris, have you been able to duplicate it at all? To recap, I have a ~100mb file with around 150 layers open (this problem is not unique to this file size or layer count - it happens on small files in both regards as well). Most tasks between PS CS6 and PS CS5 are pretty comparable, except for the pan with the hand tool, or double finger pan on the trackpad. I use this tool all the time and the jagged movement really screws up my workflow, especially on larger files.

I am experiencing this problem in its worst form on my macbook air, i7 1.8 ghz w/ 4 gigs of ram, os: 10.8. Before you blame my specs as the culprit, please remember the same pan on the same file is at least 2x as fast on PS CS5 than it is on CS6.

As noted at the top of the discussion: yes, the known problems are being worked on.

Chris, is the layer thumbnails slowdown issue being worked on, or you can't even reproduce it? Is it an isolated or widespread issue?

If it's related to CPU and video card, I'm on Core 2 Duo 2.4 Ghz, using nVidia 9400M and 9600M GT. Mac OS 10.7.4. All CS6 updates applied.

Extreme slowdowns are occurring when layer thumbnails are enabled (especially nudging multiple layers).

Thanks
