CC 2014 is incredibly slow. I'm using best hardware available from apple and I can't get any of 5 MacPRO's as least halfway like CS6.

(3.5 GHz 6-Core Intel Xeon E5, 32 GB 1866 MHz DDR3 ECC, AMD FirePro D500 3072 MB, 1Tb Flash storage)

OK, so we need to know what is different about your systems that might be causing a slowdown (compared to millions of users not seeing a slowdown on the same systems).

Do you have any third party plugins? Have you tried disabling them?
Do you have any utility programs installed? Have you tried disabling them?
Do you have any drivers installed (tablet, mouse) that might cause a slowdown?
Have you checked for corrupt fonts or OS font caches?
Do you have any network volumes causing problems? (SMB is still a problem on MacOS)

Hi Chris,

I've tried to figure out what might be causing the slowdown. Only thing we have in common in systems is one mounted SMB volume, Wacom tablet drivers and ColorNavigator6 (screen color management). Otherwise they are relatively clean. We don't use fonts, no plugins or utility programs.

So even in fresh new computer. Only Wacom Intuos drivers and photoshop CC 2014, CC and PS6 installed. There is big difference in rendering rates between photoshop versions. In PS6 brush strokes or turning layer visibility on and off appear in relatively good rates. Probably in less than a half of the second. While on CC 2014 it takes solid 6.

OK, so there is definitely something wrong with the system (CC 2014 is normally the same speed or faster than CS6).

Try disabling GPU drawing and restarting Photoshop - the cause could be a video card driver (especially on MacOS 10.10).

Have you updated your wacom drivers?

Are you showing rulers on the document in CC 2014? (a known MacOS 10.10 performance bug, which Apple is still working to solve)

I have tried disabling GPU drawing and it seemed to be even slower. Wacom drivers are updated. Rulers are off.

Here is a simple test I did:

On the top I have photoshop CC and under it you can see CC 2014.

I have opend same file and created black layer then had deleted 100px diameter area with eraser tool with same settings on it.

On the bottom you can see differences in timing.

As you can see brush has no steps set on it. Imagine brushing with all brush settings on such speeds. Its unbelievably slow.

Try turning off font previews next (to avoid corrupt fonts or OS font cache).

Tried that as well.

I have found that if I zoom out >100% in CC 2014 performance changes and it works smooth and fast. Maybe that gives a clue where the problem is?

Yes, that would indicate that a large part of the problem is in the video card driver, or something else causing slowdowns in basic drawing on your system. (we have seen problems with a driver called "logmein" which gummed up drawing operations).

What would you suggest to do? How I would know for sure where is the problem? Photoshop CC seems to handle files better for some reason.

Photoshop CC 2014 is normally the same speed, or slightly faster, than CC. But there is something odd about your system causing a slowdown when drawing images.
If you are using MacOS 10.10, you might want to try downgrading to a stable and more performant version of MacOS (10.9.5 or 10.8.5).

Otherwise we'd have to profile your system to see exactly why you are slowing down when other users are not (after ruling out known OS slowdowns/bugs).
