P: Weird Brush size animation very slow using keyboard (Windows)

[Jqqerry]

Hi. I'm posting a question again. There are many people who go through the same phenomenon as me.

I'll tell you exactly what the problem is first.

Like you and I know when we want change brush size, press keyboard shortcut [ + ].

No matter how long I press, the size of the brush should change. Because it's always been like that.

But if you look at the attached picture below, there are many differences.

in photoshop2015.5 * very smooth, It changes and shows exactly how much I press.

in photoshop2021 * something wrong. You can only see the first and last brush changes in size. In the middle, it appears to be slow (or broken) as if there is a delay.

Someone says. Why don't use a drag shortcut(Alt + Mouse Rightclick and drag)?

Yes. I know that. However, use keyboard is more comfortable to me. And as you can see from the attached photos of Photoshop2015.5, it's very soft as like drag shortcut.

brush panel is not important and turn off already.

i tried many things. Check this first..

1. Reinstall Photoshop2021, Reset Setting Pref.

2. Tried other version(2020, 2019,2018). But the same. *But funny thing is... My main workflow takes almost in photoshop2019. And A few months ago, I used to use it smoothly and well without this delay

3. Reinstall GPU nvidia Driver, and tried other every version. But same results.

4. So... I Reinstall Windows10(Clean install from microsoft, Not recovery) * I think I've formatted it about six times so far. 😃

My computer is no problem. It's new.

Ryzen5600x, Ram64GB, 2070Super GPU, Nvme SSD, Windows10

https://feedback.photoshop.com/conversations/photoshop/photoshop-2018-brush-size-animation-very-slow...

I saw this post, and he tried 2015.5, works well.

So... What should I do now?..

* Is there a solution I can try? (like turning off some settings, changing the registry...

Why do I have to feel this slow brush change speed with my good computer specification when I've become a version-up paying monthly subscription fee?

Hey guys, 

I've been using Photoshop CC for sometime now. Since the newest update, when I try to increase or decrease my brush size using the keyboard shortcuts [ or ] there is a significant amount of lag.  Before It would seemlessly resize and visually go through each sizing stage. Now it skips about every 40 pixel sizes and adjusts (lags) to the new size. Strangely enough, my Wacom Intuos touch ring does not share this same problem with my keyboard.  It seemlessly transitions through each stage of resizing the brush. Thoughts?

My PC specs are beyond professional grade. It's for sure not a hardware issue.

Hi, have you checked if there are driver updates available for your graphics card?

[PECourtejoie]

Hello, please post the contents of Help>system info, so that we know if there is a third party plug-in, or a out of date driver somewhere.

Does it do it if the wacom tablet is unplugged?

[AndrewGlassmanArt]

I updated my Nvidia drivers. Same issue persists. I tried unplugging the Wacom tablet, no luck.

For me the solution was to set my desktop scaling factor to 100%. Scaling seems to have an negative affect on brush size shortcut in Photoshop. If that doesn't work try to close the brush panel. Updating size on the panel seems to create a delay on brush size keystrokes too.

[pstruchy]

Andrew,  did you ever find a resolution?  I am experiencing the same issues. 

[teryakiwok]

Same here. Just made a fresh install of the latest PS CC and adjusting the brush size using the keyboard lags like crazy. If you tap it in increments it's fine but if you hold it down as I have done for the last decade it now hangs and then appears when it catches up. Its highly annoying.

[Jqqerry]

I posted a question a while ago, but I'm writing again because I didn't get a satisfactory answer.

As you can see from the GIF file, you can only see the beginning and end of the brush by pressing down on the [,] keyboard shortcut and changing the size of the brush. I can't see the change in the middle, but it's cut off. (Lag..? Delay?)

Some people say. You can't keep up with the keyboard. That's what they say. That's exactly what it wasn't. The brush has always changed in size as smoothly as I'm pressing it.
And I know because I'm a professional change of size through right-click. But I prefer to use a keyboard.

The size adjustment of the brush is smooth in liquify. If you adjust it like this in Photoshop, it looks like that.

Does anyone know why and how to fix?

The list below is what I've tried.

1. Reset all setting

2. Re-installing 2019, 2021

3. Reinstall Window10,,,,

4. update gpu driver

5. change gpu

I'm writing it down in advance because I think someone will say that my computer specification is not good. And it was adjusted very smoothly on my computer until last week. Please don't conclude that it's the way it is.

windows10 21h1, ryzen5600x, rtx2070super, ram32g

photoshop2019,2021 Both are the same problem. Updating to the latest version is also not a solution.

Somebody help me.

Few years ago, I've seen someone like me on Reddit who goes through this all of a sudden. There must be a solution.

[Kevin Stohlmeyer]

When you say "Change GPU" - Photoshop does not do well with two active Graphics Cards.

See this page on configuring with two (or more) graphics cards:

Configuring computers with multiple graphics cards. 

[Jqqerry]

No. not two GPU.

i mean, 

I wasn't using two GPUs, I was using 1060 before. And I thought it might be a problem with the graphics card, so I updated the driver and changed the graphics card to 2070. Please read it properly.

[Kevin Stohlmeyer]

I did read it properly and you stated:

4. update gpu driver

5. change gpu

You did not give specifics until your response.

[Jqqerry]

Yes.

Previous GPU : 1060 3gb works well.

and As I think about it now, it's not a problem with graphics cards. Because it worked well back then, but it suddenly changed one day.

Now GPU : 2070 super 8g

GPU driver was Feb, this year from nvidia.

And i tried update every month... and back orginal.. but not work anymore.

i don't understand this happen...

[dumaker]

Hi! I have the same problem and none of the solutions I have seen work for me. Did you find a solution? 😞

[Trevor.Dennis]

Frame 10

Frame 11

I've turned on all 40 layers here, and set them to Lighten and you can see there are only four steps in size for the ellipse.

Did you make the layers?  Did you use Make frames from layers to make the frame animation?  We can (I) can tell you how to produce the layers and make the animation with smooth steps if you need advice.  

Actually I am going to say more than four steps because the lines are quite thick in some areas.  If we zoom in we can see probably seven steps.  There should be 20 steps, because the last 20 frames are the same as the first 20 frames in reverse, buit you knew that. 🙂

[Trevor.Dennis]

Ahhh,...   LOL I didn't read your post properly, and I can see you are actually concerned about brush change size.  I'll have a closer look

[Jqqerry]

😃 LOL

I understand.

I think there's something I don't know......

It's not the problem with my computer that's for sure. And I don't think it's even Windows10' problem.

Well, all I can think of is that there's been a difference in the version since Photoshop 2015.5.... What's that?

[J453]

Thanks. We've asked engineering to take a look at this.

[Jqqerry]

I hope it's settled.
What I can tell you for sure is a mysterious delay that has occurred since 2015.5 version.

I tested all the versions.(2017,2018,2019,2020,2021...)

And Only version 2015.5 survived...

Now, I have no choice but to use 2019. (Because 2018 doesn't fully support HiDPI, 2019 is faster than 2021. Of course, it's much slower than 2015.5).... =(

Please let me know if there is any change. I've been waiting for years.
And if I can change any file in the Photoshop folder or modify the registry to fix this phenomenon, I would really appreciate it if you could tell me the answer.

[Jqqerry]

few days ago, I posted a new post.

https://community.adobe.com/t5/photoshop-ecosystem/p-photoshop-2021-weird-brush-size-animation-very-...

The only solution is to use "Photoshop 2015.5".

or if you using 2k or 4k HighDpi Monitor, have to use 2019... 2018 is support Hidpi, But it's not perfect..Ofcourse 2019 is brush slow =(

I'm using BenQ's 4k monitor, and I have no choice but to use 2019 now....

About Brush Change delay ....Honestly, I almost gave up.

And Funny thing is.... When you press hold [ + ] for change brush size, it's delay. Right?
But Try moving your mouse while pressing the keyboard the same way.

And then you can see brush changing. It's very weird... =(

After years of pondering and looking into this problem, it is not a user's problem.

Not Hardware problem, Not Winows's problem , Not Setting, driver things problem...

Just Photoshop's Problem after 2015.5 version.........

[specialty-mac]

I've had this same issue for years on multiple Macs using different versions of Photoshop and different versions of MacOS. Super frustrating! I've tried training myself to use the control+option method instead, but I just can't get the muscle memory to kick in.

[Emi Xikes]

The new PS version (23.0.1) sees the resurfacing of an old bug, that plagued some older versions before.
If the brush panel is open, changing the brush size with hotkeys is very laggy and slow.
Before anyone asks, yes my workstation is sufficiently powerful (12 core cpu, 32GB ram, RTX4000, SSD on pcie 4.0). There are no problems on my end.
This is a software bug.
Fix it ASAP!
Demonstration:
https://youtu.be/i2MvHMtnEVk
Reverting back to version 22 until this is fixed.

[J453]

@Emi Xikes Are you actually hitting the bracket keys [ ] or using the Wacom touch ring?

[teryakiwok]

Yeah I'm sick of this bug. I remember using CS6 on a budget PC many years ago and it was perfect. Today using CC on a high end machine it's infuriatingly laggy.

[blented]

Anyone ever find a solution for this?

Same issue, fast brush resizing in older versions, switch to the latest photoshop, brush lag is crazy.

The only fix I've found is to hit tab to hide the interface completely, then it's fast again, but if the brush pallete is visible it's glacial.

[PECourtejoie]

Hello,  update to Ps 23.1.1 as it has a fix for this very issue.
