I will post a thread on apple support if someone will direct me to the appropriate forum. I think we all should. The only way to get change is to make it happen!
I have MacbookPro 15 Retina Mid 2015 with Nvidia 750 and Adobe programs currently lag to the level when i simply uninstalled them. The most surprising thing is to see Dreamweaver text lag during scroll down and text selection. I had to buy Parallels desktop and install Windows 7 in order to work with Adobe programs, they way smooth with no problems on PC.
So, good news, turning off the Rulers helped out my lag problem... after 3 months with a new computer. So, I really appreciate all the folks submitting stuff, thanks guys. My most recent work around was resuscitating GIMP, doing basic silhouettes in there (no lag), and cleaning up lines in Photoshop. Phew! But, after 3 months of frustration I'm gonna rant a little. And to the guys who run this board, you're just doing your jobs, most of us get that. So don't take this too personally. These are just a couple of observations:
1. After the break through about turning off the Rulers came out one of the Adobe folks said "Apple has known about the Ruler problem for awhile." So, logically, so has Adobe. Yet, "Turn off the rulers" was not the first thing up on the help menu. No, I backgraded my Intuos 5 Wacom, I updated Yosemite, and played around with preferences for AWHILE. ALL of which would have saved me hours (which... is like, 25$ to 40$ an hour for some retouchers and digital painters?). Seriously! And, I know it's your job, and you can't say "Adobe bad" you have to say "apple bad, or intuos bad". But it's seriously annoying.
2. Here's some other workarounds I considered: Affinity Photo for 50$ sounds really nice. You know, it'll never be as up to par as Photoshop, but it'll be nice to have around next time there's another glitchy upgrade and all the bigwigs from the Billionaire companies want to point fingers at eachother.
3. Here's another thought: 3D folk have a way to get back at Maya, and Modo and all those guys when they get pieved: Blender. The Blender foundation puts out a really nice product and the course of that product is completely user driven. We need a Co-op Photoshop. Gimp is a big piece of crap, it can't really compare. If you want to do stuff and don't want to pay any money, GIMP to the rescue. But, if we funded it as well as we fund you. it wouldn't be. I might just do some technological insurance myself... maybe give the GIMP 2$ a month from now on. Just in case. And if everyone who got mad about this did that... well, Adobe would get some competition, and we all know how good that is for all of us.
If the problem is ours, we admit to it and fix it as soon as we can.
But what remains after we fix our problems are bugs in OS and third party code - which we cannot fix, and sometimes cannot even work around. So the only thing left is to document the bugs for the OS or third party, then wait for them to be fixed.
This is talking, Mac users are blaming Adobe and Wacom for this lag problem, and almost nobody are posting on Apple support to fix this problem.
Adobe should be more clear that APPLE should FIX THE LAG PROBLEM and users must complain with Apple, maybe they finally fix it.
I found something which seems to remove the lag completely. And, so far the culprit seems to be Apple (or possibly some program(s) which are able to shift around process priorities). After a few rounds of re-installations, restarts and trying some of the helpful-ish suggestions from this board, I still had no luck.
The lag was inconsistent, depending what else was running. And, ultimately, I tested out an idea which seemed ludicrous at the time...
Is it possible that Apple's current OS X was giving Safari (and other web browsers) higher priority than the basic needs of a GUI-driven computer? More specifically, is web-browsing considered more important than dragging the cursor around?
After a brief search on system priorities, I read up on "renice" which is a means to alter the "niceness" of your system processes. The less "nice" a process is, the more resources it demands for itself. It's a sort of inverted priority system in which negative values (negative niceness) are entitled to more resources to run.
After giving WacomTabletDriver (use Activity Monitor to find its PID) a negative nice value, I haven't had a single lag problem.
So, something is either wrong with the latest OS X, or the latest Wacom drivers, or I have third-party software which has shifted around these priorities or taken precedence over them.
Through this process, an Apple-made mouse performed without issue. So, the processes driving that thing were given their proper due.
I suspect that there may be some shared functionality between Safari and the Finder. And, third party accessories like Wacom are given short shrift. It's also possible that setting the Wacom Driver niceness will have to happen on every reboot of the machine. So, I'll have to work on a startup script for that.
Until then, in a Terminal window, the command I used was:
sudo renice -1 495
Sudo to make sure it's executed by root.
"renice" to change the "niceness" of a running process.
Negative one to make it slightly more greedy (you may need a little more but, go in baby steps).
And, finally the PID I learned from the Activity Monitor.
I suspect the other fixes that people have tried were mostly killing processes that somehow took precedence over their Wacom Drivers on their particular set ups...
Yeah well let's see how many new bugs will be introduced with El Capitan... Another nightmare to come. I decided to revert back to Mavericks... Will do this tonight. Really disappointed to have bought into the CC monthly subscription... Thankfully I still have 22 days to cancel...
Any updates here? Brush tool is still lagging with all softwares and drivers up to date and all tricks (like remove ruler, reset preferences and so forth) applied. I can't believe that Photoshop brushes can still lag in 2015 with the speed of our machines... It's only 2D images!
Amazing how nobody wants to take responsibility and fix the dam thing... Same thing happened when I bought my macbook pro 2013... Photoshop would brush freeze every 5 minutes. I needed to revert back to older OS X to have something somewhat stable but you can't go older than the OS it ships with... I'll probably end up reverting back to Mavericks...
I waited 8 freaking months before upgrading to Yosemite... Apparently they didn't have enough time to fine tune it yet... They should stop releasing BETA versions and wait until their software is ready for the real world (Adobe, Apple and Wacom).

Chris, thanks for your reply. Any idea why briefly utilising the mouse will kick start the pen to behave as normal? BTW the rulers have no effect on this issue with my Intuos Pro.
Lastly, could I ask that you take a look at the following that is causing some distress to myself and others, so far there has been very little communication from the Adobe camp regarding whether this other bug is in the process of being rectified: Re: Why does a path deselect when you convert it to a selection?

btw, the lag on my Intuos Pro was ridiculous. Totally unusable. I found that to cure the lagging, simply click the mouse button and move the brush slightly with your mouse and it seems to give the Wacom a kick up the backside and the lagging disappears, making the pen usable again. Do this whenever it starts lagging again sometimes after making a selection etc... A bit of a pain, but has worked for me. Seeing as Wacom and Adobe have completely ignored the issue... Which wouldn't be the first time...
Is there an official bug report page we can follow? Because im running the latest wacom plugin, OSX version and Photoshop version up to this date (jun/25/2015) and I STILL have issues.
Disabling the ruler only solves half of the issue, as I get MAJOR slowdowns when using brushes on photoshop. A 2500x2500x 300dpi document with a 125px wide brush KILLS my computer, a 16gb retina macbook retina.
And this isn't an issue with THE COMPUTER, as I tested the same file size and brush size on Photoshop CS6 and IT RAN SMOOTHER.
I'm sorry, but how is this not a top priority inside adobe? How is it that a CS6 discontinued version of photoshop runs better on Yosemite than the official, up to date version?
I bought the entire suite as a student knowing that adobe would always be working on the best for our products, but this CONTINUOUS issue has started to make me question that...
Very good, now I would only like to make sure, that Adobe is also aware of very poor performance of Illustrator in OS X on new mac pro (2013).
Seriously? We pay 4000+€ for a machine to work on, and then Adobe decides it is best to give hardware rendering support for illustrator for Nvidia and Windows only. Way to get rid of your customers as same as Apple.
To fix Photoshop things Apple needs more than 6 months and you Adobe didn't do much to help it seems. What I mean is that Photoshop was originally made for mac, but now it runs everywhere else better than on mac. Even Apple make new computer with dual GPU where one GPU is dedicated for computations, but you make no improvements on basic things like brush tool to take advantage of that new hardware.
Adobe and Apple should work more closely, they should make new computers and make sure everything runs smoothly on them, and you Adobe should make sure to fix bugs and make use of new hardware and features. It's totally not funny buying computer for a big price and then watch 1FPS while working in Illustrator or Photoshop. It is more than 1 year after this mac pro model release and almost 6 months of Yosemite release (you also have beta access before release to test things and to prepare) and we are still in bugs over our heads that should never even be released by Apple.
Sorry to be so critical, but we are actually paying for "premium", but we are not getting it. And yes, I count your software as "premium" as it is best on market and offering much more, but still instead of releasing constantly new version every year, take a break, deep breath and make next version only a fix and support to new hardware. More than new shiny features we need flawless performance and best use of hardware we (over)pay for. Apple and Adobe should be ashamed about your care of most paying customers!

Hi People
One thing that worked for me was going to your 'Wacom Tablet Preferences' and turning off 'Tip Double Click Distance'. I'm having less problems and hopefully will help you guys.
