Photoshop cc 2019 Brush Lag and Bugs

Hey guys, after updating to PS CC2019 I'm having a ton of issues with the brush tool.

1. After I make multiple consecutive brush strokes photoshop cant seem to quite keep up, if I make 5 brush strokes in rapid succession the first one may appear in real time but they rapidly begin to fall behind where my cursor actually is. This does not happen in cc2018 where i'm using the exact same brush on the same document size. These are simple round brushes on small documents, I'm really not pushing it. (This may have improved with a preference reset its hard to tell)

2. It seems to occasionally (every 3rd to 5th input) skip a brushstroke, making only a single low opacity circle or no mark at all without drawing the rest of the line. I can scrub the cursor across the document at full pressure and it makes no mark till I lift the pen off the tablet to make a new mark.

3. If I hold a brushstroke for any more than a second or two I get a busy cursor (a ring of rotating dots) this happens no matter if Im using my mouse or the wacom. It no longer allows me to see the brush tip shape but will continue to make the brush stroke just fine. This happens no matter how small the document or how simple the brush.

To clarify I have reset my photoshop preferences repeatedly, made sure I have updated wacom drivers. These seem explicitly connected to 2019s brush engine because I can compare them side by side and not have any of these problems in 2018. Also their performance preferences are set up identically but I have tried increasing them in 2019 and it seems to make no impact. Thanks for the help!

    Changing the smoothing to 20% totally made a difference  for me.

    Nothing helped me. No deactivating ruler or setting Smoothing to 20%.

    I have a Mac Pro (Black ton) 6-Core 3.5 Ghz with 32 Gig Ram

    Two FirePro D500 3GB

    Mojave 10.14.5

    I deleted all caches, preferences, deleted photoshop, installed new, formated disk installed system and all new.

    Problem still there. It doesn't matter if I am using wacom or mouse. Brush-Tool is painting dots instead of lines.

    I tested every tip I found on net. I am very disappointed about this bug.

    I cannot use photoshop. I have to work with 2018. This version is stable and working.

    ADOBE PLEASE FIX THIS.

    The problem still exists. It is a shame for adobe. I can not work. I could downgrade to 2018 version which works. It is not a problem with wacom drivers it seems to be a problem with graphic cards. My iMac from 2018 works better than my mac Pro. For a subscription service it needed to much time for adobe to fix this. 2019 is totally useless for me. No work around helped. ADOBE: FIX THIS.

    There is this moment no workaround.

      They will never fix this, FLYINGFOX​. Some of us have been complaining about this bug for five+ years, but Adobe ignore us and just tell us to reset our preferences. Nothing works, the workarounds are ineffective, and the core tools in Photoshop remain broken. It has actually made me hate my job which I used to love. Photoshop user since v.3.0 and have watched in horror as this once great application has turned into a laggy, buggy, bloated mess.

      I've just tried a brush test comparison between CS6 and CC2019, the difference is remarkable. Not only in brush speed, but selecting layer apply modes, drawing paths and other day-to-day operations are all slower and stickier in CC2019. CS6 is responsive and reacts to user input immediately, but in CC there is a very perceptible lag and slowness to everything.

      As for using the brushes, painting, working on masks and retouching, CC2019 is like swimming through bricks. It's an unpleasant and deeply frustrating experience. Switching back to CS6 is back to how you remember it, it just works without any lag or stickiness.

      My test machine is a top of the line, fully maxed out iMac Pro. Even on this machine, Photoshop is unusable.

      Affinity Photo is absolutely lightning fast on this machine and a real pleasure to use. Just saying.

        Since upgrading to the latest version of PS CC (20.0.4) and the latest version of the Wacom tablet driver (6.3.34-2), my brush lag has actually gotten way worse. You'd think after this long that this problem has been around, it would have gotten fixed at some point. I'm so completely frustrated with this situation. I've tried literally everything mentioned in this long thread except for downgrading PS, but I'm afraid that's probably going to be my last resort. It's a terrible course of action though to have to move backwards especially when we're now paying a subscription-based model and should be getting all the latest and greatest updates as they roll out on a consistent basis. Is anyone experiencing worse lag with the latest versions of PS and Wacom drivers? Has anyone successfully been able to come up with a workaround that fixes the problem for good that hasn't been mentioned in the thread already?

          Sorry for reporting, but we have a bug in Brushes, they have lag errors and textures.

          The "coolest" is that it affected the created brushes.

          Adobe needs to learn how to stop creating bugs with each new update, or do not know, that there are other tools for the market for professional illustrators!

          I'm losing my temper!

          I don't even have rules turned on...and my brushes/clone tool etc are all still laggy.
          Tried updating, still the same.
          Adobe doesn't give the option for 2018 (19.0) to be downloaded....now what?!

          You can choose older versions in the CC app to install them, back to CS6. ;-)

          CC 2018 does not have the lag (and all the other problems) that CC 2019 shows.

          It won't let me choose anything between 18.1.6 and 20.0
          It only offers me 2017 & 2019 for whatever reason.

          Can someone explain to me how come Adobe still hasnt fixed this after 6 months? They have a functioning Photoshop app, which is the 2018. After that amount of time they couldn't figure out what makes 2018 works and kills 2019?

          This is crazy. Very sad to keep having to come back to 2018. Hopefully they learn the lesson for 2020.

            This is still a problem in their latest version 20.0.04.

            Having the rulers turned on causes wacom input lag using photoshop.

            Still a problem after all these months.

            Adobe is going to be more and more useless for me. As a professional I need to have a program working as it should be. All advices from adobe are not working. I have a beast machine here with 32 gb ram, 6-Core MacPro with 2 FirePro D500 Cards. Nothing helped.

            Brush Lag exists and Liuqify function also not working.

            PS 2018 is working for me or change to Affinity. :-( I am really disappointed about Adobes update policy and bugs and bugs and bugs.

            By the way, I have the same problem on my 2018 iMac with similar hardware specs.

            Brush works without extreme lag only with smoothing on 0% in PS CC 2018 and 2019.

            Adobe management told me to downgrade to 2018 months ago because there were SO. MANY. PROBLEMS. Still too scared to upgrade to 2019. CC is a rip off.

            What the heck Adobe. I also had so much wasted work time because of this.
