Jacek, That video was very helpful for us and we can now reproduce the TTF v OTF issue you describe! Now on to debugging it... Thanks, Adam ... View more

Jacek, So is the application only slow when you're using TTF fonts (Arial) and does it perform as expected if you're using OTF fonts (in your case Myriad)? Just trying to narrow our focus here. Thanks,Adam ... View more

We're very concerned about this issue and have been working non-stop to find a way to reproduce it in-house.  We've found two ways to get our systems into a similar state, but are still unconvinced that what we're seeing here is the same thing as what you're seeing in the field. I'll expand my offer from before: if you're seriously interested in working directly with the Photoshop team to debug and hopefully resolve this issue you'll contact me directly at:  first name dot last name at adobe dot com The last time I asked for volunteers I had one person offer to have us visit in WA, however she was just seeing a type tool issue that was mitigated by turning off font previews - what others are reporting here sounds like it affects far more than the type tool. I'd be willing to remotely log into people machines if you don't want me to physically come to you and your system to work on this, but I'm willing to do that too (especially if you're located anywhere west of the rockies).

A quick update from the Photoshop team: We need people who are seeing this issue on Windows 10 to try the following to see if it mitigates the general slowdown of PS CC 2017 (note that for this workaround you don't need to disable anything in Photoshop proper, just Windows Defender).... 1.  Go to Settings 2.  Choose Update and Security 3.  Choose Windows Defender 4.  From the Windows Defender Preferences look for 'Exclusions' and click on 'Add an exclusion' 5.  On the following page, select 'Processes' and then click on the 'Exclude a .exe, .com, or .scr process' 6.  In that field type the following:  Photoshop.exe 7.  then click OK 8.  Re-launch Photoshop CC 2017 Is performance better with this change? Thanks,Adam ... View more

The good news is we think we've found a system we can reproduce the issue on in-house (after trying for the past 3 weeks). We're currently working to debug the issue, but in the meantime we'd like people to try this: 1.  Go to the Adobe Create Cloud application and click the gear on the right-hand side and select Preferences... 2.  From the Preferences dialog, click the Sign Out button, then quit the Adobe Creative Cloud App (using the same gear dialog) 3.  Reboot your system 4.  Sign back into the Adobe Creative Cloud (either in the ACC app itself or by launching PS) Does this help with overall performance in CC 2017? ...

I'd really like to get this issue resolved asap, so if anyone would be willing to work directly with me on it, please contact me directly at:  first name dot last name at adobe dot com I'm specifically looking for someone who is seeing all aspects of Photoshop run slow, and preferably someone in the CA bay area that I could visit in-person (anywhere west of the rockies would work too). Thanks, Adam ... View more

Two more things to try (one-at-a-time please): 1.  Disable GPU - go to Preferences > Performance and uncheck "Use Graphics Processor" then quit and re-launch PS 2.  Disable Extensions - go to Preferences > Plug-Ins and ensure all the check boxes on that panel are unchecked (turn off Generator, Remote Connections, Allow Extensions to Connect to the Internet, and Load Extension Panels) - then quit and re-launch PS Do either of these changes help with overall Photoshop performance? Thanks, Adam ... View more

There's a possibility something else running on your system (could be another Adobe process) is slowing CC 2017 down.  What I need is your help (and others that are seeing this) to post a screenshot of Task Manager (Windows) or Activity Monitor (Mac) that shows the applications using the most CPU when Photoshop is running slow. On Mac Activity Monitor looks like this (found in /Applications/Utilities/Activity Monitor): On Windows Task Manager looks like this (to get to it either press cntrl-alt-del or right-click on the task bar and select Task Manager): Both of my examples above are cases where PS is running as expected, without issue. So from my own anecdotal experience, I just upgraded from 10.11 to 10.12 last night and there was a stuck process, part of an Apple keychain update, that was using 100% of my laptops' CPU.  Everything was running slow on it until I unstuck that process. I would really like to know if when Photoshop is running that there's something else hogging up your systems' resources. That could go a long way to help us figure out why you're seeing PS run so slow. Thanks,Adam ... View more

I know people have been posting about Mac issues, but I'd really like to focus on the application running slowly on Windows. In an attempt to diagnose what's going on I need the following information (try each of these one-at-a-time please): 1.  Have you tried to run the app with the Creative Cloud app quit and the internet disconnected from your system? 2.  Do you have any anti-virus software running on your system?  If so, have you tried disabling it and then running Photoshop to see if the files open faster? 3.  Finally, if all else fails, try navigating to Windows (C:)\Program Files\Adobe\Adobe Photoshop CC 2017\Required\CEP and moving the CEPHtmlEngine.exe to your desktop then re-launching the application (you'll want to keep it so you can move it back - CC Libraries and other pieces of Photoshop will not run without it, but this could help us diagnose the issue). 4.  Turn off font previews (Type > Font Preview Size > None - then quit and re-launch PS) 5.  Disable the Spaces plug-in:  navigate to (C:)\Program Files\Adobe\Adobe Photoshop CC 2017\Required\Plug-ins\Spaces\ - then rename Spaces.8li to ~Spaces.8li - then quit and re-launch PS (renaming it later to remove the '~' will get the plug-in to load on future app launches) Do any of these changes help? If not, and you're located anywhere in the CA bay area, let me know and I'd be willing to come visit in-person to help diagnose this. Thanks, Adam ... View more

A couple things to try to diagnose this (for Windows users, if you're on the Mac on seeing a slowdown with CC 2017, try disabling font previews - Type > Font Preview Size > None): 1.  Try disabling font previews (as described above) 2.  Select the application executable and right-click on it and select to run as Administrator 3.  Try creating a new Admin user and launching PS from there If none of the above three suggestions helps, then please launch Task Manager and take a screen shot of the active apps when PS is running and post that here so I can take a look.
