    Why is Photoshop CC 64-bit is slower than 32-bit?


      I have a very powerful system.


      HP Z820 Workstation

      Intel Xeon CPU E5-2670 0 @ 2.60 GHz (2 processors)

      64 GB RAM

      64-bit OS

      Windows 7 Pro

      Nvidiea GeForce GTX 690 (2 GPUs) 4 GB VRAM ea.


      But here's the deal. When I'm painting or drawing down to the pixels within Photoshop CC 64-bit, it crawls, the lag is so great!  I have caching on an SSD card even.  Then I had an idea, I switched to the 32-bit version of Photoshop CC and everything is good, it's faster than the 64-bit version. 


      What gives?!?  Why would the 32-bit version be faster than the 64-bit version?

          Does not make any sense as with 32 bit version you can only use 3.4 gig of RAM, rather than the 64g you have installed.

            It's not normally slower; usually it's 10% to 20% faster.


            I suspect something may be going wrong in your display driver.


            Try alternate drawing modes in your Preferences - Performance panel, [Advanced Settings...] section.  Remember to close and reopen Photoshop after making changes here, and before testing.


            It might be helpful if you'd open Photoshop 64 bit, choose Help - System Info, and post the data here.

              I know, it's VERY odd. I can actually do things faster in 32-bit mode Photoshop CC. I'm painting a very large digital painting. 180 dpi, at 40" x 24" (for print) - When I first started painting it, I was using Adobe Photoshop CS5 and it was very smooth to paint it, very fast.  But now I've upgraded to Photoshop CC and the 64-bit is VERY slow, and lags terribly.   Then just on a whim, I opened up Photoshop CC 32-bit and could paint just the way I did with the old CS5, very fast and smooth.  It's like Photoshop CC 64-bit was a major step down in performance.

                Two things:


                • >>gpu[0].DriverDate="20130912000000.000000-000"

                  Your display driver isn't old, per se, but I'm pretty sure nVidia has released a newer one since last September.  I'd try updating it from their website.


                • You have a fair number of 3rd party plug-ins installed.  I might try temporarily disabling them (which can be done by holding Shift down when cold-starting Photoshop).  It's quick to test and if things speed up you might need to disable one or some of them until you can get a fix from the 3rd party vendor.



                That's a nice system.  It ought to be flying through Photoshop operations.

                  yeah, I'm a production artist and I also do 3D and 2D Animation, hence the heaftiness of the system. I work with Adobe After Effects and Cinema 4D as well - neither of those give me problems, but only recently has Photoshop been very slow. I've had those plugins for years now and never had problems with them on CS5.  I'll look into upgrading my graphic cards. I've been hinting to my IT to get me Nvidia Titan cards. This system hsa the capability to go to 512 GB RAM which is sweet, though I don't think I'll get that much.  For animation though I'd like to up it to 128 GB though.


                  I'll definitely check those plugins for sure, thanks!

                    StratoArt Level 1

                    I temporarily disabled the 3rd party plugins (SHIFT at PS boot) however it didn't help. It was still slow. It's even slow to zoom in and zoom out. So I'm going to check on the upgrading of my video drivers.

                    • 7. Re: Why is Photoshop CC 64-bit is slower than 32-bit?
                      Noel Carboni Level 8

                      I have high hopes for the driver update helping.


                      Don't forget to also check those alternate drawing modes.


                      I develop OpenGL software and once upon a time I found that with certain data formats nVidia Quadro FX drivers were actually running some operations on the CPU instead of in the GPU - causing just the kind of slowdowns you described.  That leads me to add one thing to my previous advice:  Try also changing the 30 Bit Color setting.  Again, make sure you close and restart Photoshop after making GPU setting changes.

                        Usually this is an issue with the Video Drivers. You may also want to double check your advanced preferences and see if you have something there that is out of the ordinary, it could be that somehow the amount of RAM it is accessing has been reset, you can also optimize your cache levels etc.

                        • 9. Re: Why is Photoshop CC 64-bit is slower than 32-bit?
                          StratoArt Level 1

                          Well, I've done a lot of things. Updated to latest drivers. Temp removed 3rd party plugins (rebooting Photoshop and computer between major changes too).  See, the thing is, I have this same problem at home on my Windows 7 machine there too. It's not as fast as my HP workstation at work.  It's an AMD computer that I personally built and upgraded. Has about 16 GB RAM and the AMD Radeon 6800 card in it.  Not as fast as my HP but still good.  I have Photoshop CC there as well, and it's the same deal - 2 completely different computers, 2 completely different memory and GPU and CPUs yet the same exact problem.  


                          In both cases home or work, when I'm working on this one particularly large digital painting 7200 x 4320 pixels at 180 ppi (40" x 24" - a normal format for my work) - in both cases home and work, painting is faster and smoother in the 32-bit verson of Photoshop than in the 64-bit version of Photoshop CC.  And I've upgraded both GPU drivers on both computers (work HP and my personal computer at home) and STILL it's slow.


                          So, my conclusion is that there's a problem with Photshop CC in handling a large document. It only has 3 layers.  Here's the deal.  I NEVER had this problem with Photoshop CS5 and below.  I actually started off painting this particularl painting I'm having problems with back in Photoshop CS5 with Windows XP on an older computer even.  But now, when I'm doing current digital paintings and having to zoom in 100% to work on details, it's all mind-bogglingly slow!


                          I haven't changed my workflow with digital painting. I even could work at 60 inches at 200 ppi on Windows XP and it was fast.  There's something screwy going on with Photoshop CC 64 bit and large documents, and I don't have the understanding of it all to nail down what the problem is.


                          I'll try to make a video of both my work in Photoshop CC 64bit and 32bit so you can see what's going on.

                            Perhaps the video is a good idea.  It certainly seems as though you've thoroughly checked things, but you have to believe that not everyone is seeing the same slowdowns.  I often work in documents of 100 megapixels or more in the 64 bit Photoshop and it's fine.


                            What are all your settings in the Performance preferences for each (keeping in mind that some of the settings are separate for the 32 bit version vs. the 64 bit version)?  Ideally do some screen grabs of those prefs.  Obviously any differences need to be investigated.

                              Okay, I did one more thing, something I just thought of while on my one hour commute.  I made a new document equal to the size of the digital painting I was working on that was incredibly slow.  I started painting on that new document and things seemed fine, fast and fun.   I did this before, though but before I had simply dragged and dropped the layers to the new document and it was still slow.  So somehow not dragging and dropping the layers to a new document fixed it. ??


                              So, I "select all" the layer I was painting on, copied and then pasted that into my fresh file.


                              NOW! Everything was as it should be! Fast and smooth. YAY!  Although, to be honest, I still have no idea why 32-bit Photoshop CC was smooth to work with.  But at least, the lag and slowness is now gone. I just don't get it. Corrupt file possibly? It opens fine, and saves fine, it was just painfully slow to work with. Scratching my head on that one.


                              So now, I guess, if I run into this again with one of my digital works and it starts to get laggy, I'll copy each layers (not drag and drop) and paste it into a new document. It's rather an odd thing to do, I admit.


                              Thanks guys for all your help though! It has helped me at least to narrow the problem down though I still don't know exactly what it is.


                              Perhaps this will all be fixed in a Photoshop CC update!

                                What may have happened is that all the data from your other document may have still been in the clipboard taking up resources. When working with larger documents sometimes it pays to use the Purge command in Photoshop. Just like in Premiere Pro and After Effects sometimes they can slow down when the Cache gets full.


                                A good way to monitor Photoshop performance is to use the Efficiency tool. At the bottom of the screen where you typically see document size click on it and select efficiency, then you will always know how Photoshop is performing based on how you are using it.

                                  yeah I purge all the time in After Effects.  I figured though that closing down Photoshop would purge, but I guess not!  It's a habit I will now start doing. thanks!

                                    Any chance there were a lot of pixels out beyond the edges of the visible canvas?  Maybe in layers you weren't working with at the time?


                                    I've never found a need to go to extra effort to purge the clipboard.  On a high-end system (that's free from the problem you describe) I've yet to notice any impact from anything that happens to be in the clipboard.

                                      I have both documents opened now. Both the same size. One is the one that's slowing down, the other is the one where I copied the three layers and it's in a new document.  On both of them the Efficiency meter shows 100%  yet the one that is laggy, is still laggy and slow, while the other is completely smooth - both open now in 64-bit.


                                      sooooooo, I'm going to guess it's some kind of corrupted file of some kind, weird. Oh and I purged things too.


                                      again, it's weird.

                                        By the way, slight segway...  As you have two fairly current Xeon processors, I'm curious how that system stacks up against the previous generation (I have a dual Xeon x5690 system myself).  I'm always interested in keeping abreast of current performance levels...


                                        Have you done any benchmarks on it?  Passmark, perhaps?  I see from the Passmark charts that the Xeons you have have tremendous compute power.


                                        How long, for example, does it take your system to do the Radial Blur rotation listed here:

                                            I haven't personally but I do believe my IT guy did when he got this system for me, but I can definitely try to do that. I wouldn't mind knowing myself.  I actually came off of Mac Pros which I was using for about 6 years and before that I was using Boxx Technology PC workstations.  I'm not a huge Mac guy, but at the time we were having codec issues from the particular cameras we were using and I was forced to go to a Mac. I endured it and actually liked it's smooth interface, but after about 6 years with really no good upgradable GPU (which are like twice as slow as the same for PCs) I had had it with the Macs and pleaded to go back to PC for 3D and 2D animation, and this HP workstation is what I wanted, based off of Andrew Kramer's (Videocopilot) workstation (he had an older one).  I am COMPLETELY pleased with my HPZ820. It's just that this thing with lag was a curve ball for me.

                                                  Yeah, at first when we got this system, we got it with just one CPU, but then went ahead and upgraded it to two.  I need all the power I can get for rendering for Cinema 4D and After Effects.  C4D is mostly CPU intensive and AE is GPU intensive.  I don't have a render farm...yet...  so my rendering is just done on this one computer.  I can connect to other Mac Pros and team render, something I need to look into.  Now if I could only have this much power at home!! ahhaaa!

                                                    You haven't mentioned I/O configuration...  How do you have that set up?  


                                                    I built a RAID 0 array of 4 x 480 GB SSDs for drive C:, which delivers over 1.5 gigabytes/sec sustained throughput, to keep enough data flowing that the system isn't just waiting all the time.  I don't do the kind of rendering you do, but I do graphics software development and Photoshop work, amongst other things.


                                                    I was thinking about another Dell Precision (mine's a Precision T5500, and now they have the newr T5600), but that HP is sounding nice too...

                                                      The HP is very nice. like I said, I got the idea of going HP from Andrew Kramer who did the titles to the two new Star Trek movies and he is a great resource for us After Effects guys. I guess I'm a big fan of his


                                                      In one tutorial video he briefely showed the HP system he was using, at that time it was the older HP Z800 I believe. I just said, "I want whatever he has"   and I totally am thrilled with it.  At home, I obviously can't afford a multi-thousand dollar machine like my HP, but I did build it from a New Egg kit, it's an AMD 64 bit with Corsair case and memory, I forget the exact specs of that system as I'm not sitting at it right now.  I'll have to try that benchmark test on it when I get home. Should be interesting.
