Painting with Custom Brushes extremely slow

[magicmarker]

Hi Everybody,

 

I've imported my custom brushes from Photoshop, but they lag a lot when using them in Affinity Photo. It takes a good 5-7 seconds before my mark appears, even just a single click. I'm not using a tablet, just a mouse. My brushes tend to be large (2000px), but nothing that PS couldn't handle. 

Any ideas? I thought about turning off the brush preview, but I need it to see where I'm laying down my marks. 

 

Thanks!

Have you rulers on?

Try turning them off.

[magicmarker]

How do rulers affect the speed of the app? 

Rulers on or off didn't make a difference, thanks for the suggestion though.

I don't know why... :)

But with rulers on (and certain zoom values) texture intensity strokes are delayed and appears 2-3 seconds after your stroke.

 

Can you describe a bit how is your brush designed?

Spacing, Texture, Jitters, Nozzle size...

[magicmarker]

Sure- It's a pretty simple brush (and set of brushes), but it is of rather high resolution. It's just a set of different brushes made from a sample/mark of paint rollers on paper. For this particular series of brushes, all dynamic settings are at zero. I use it to lay down large areas of a paint roller mark in a single click- I don't even drag it as if to paint a brushstroke or anything. Just a simple click of a brush, sized at 2499 px. I have a lot of brushes like this, and they all work flawlessly in PS, but not Affinity Photo. 

 

Thanks for your help!

 

I tried turning off the rulers but there was no difference in lag. Reacts the same using a tablet or mouse.

Honestly, the brush lag is so slow that I've stopped using Affinity Photo and went back to Photoshop until I have the time to figure this out. Bummer.

[paolo.limoncelli]

Mmm... Point and click with a 2500px nozzle brush works flawlessly and has no lag on my machine.

It even shows me the live brush preview...

 

Mine is a mid2012 MBPR...

So a 4years old machine... Not the very top performance champion.

 

Did you try to turn off brush preview from settings?

[magicmarker]

I'd really like to be able to use the preview, but where is that parameter located? I can't find it in brush settings or app preferences.

Thanks!

 

btw-

my machine is a 2009 2.93ghz C2D iMac, 8gb ram.

Thanks! I tried turning off the brush preview, but it didn't help. Now instead of taking 7 or 8 seconds, it takes 4 or 5 seconds for my brush mark to appear. Is there a direct support contact for Affinity? 

[paolo.limoncelli]

Yes!

 

Try to contact one of the members of the forum support

(I missed someone for sure...)

 

I'm sure they can speak to developers and give you more info.

magicmarker,

You might try making sure other apps are not open & using a lot of memory while using AP. One way to do that is to open Activity Monitor (in the Applications > Utility folder) & check the memory column. You can also check CPU usage there & see if AP or some other apps are using large amounts of the CPU resources.

Hi magicmarker,

Can you please zip and upload one or two of those brushes using this link for us to check out?

Thanks.

Thanks everyone for all of the suggestions above. Nothing seems to make a difference though. I will send you those brushes, MEB, thanks for taking a look at them. I'd like to add that I've been using them for years in PS with no issues. 

 

Something that I have just noticed is that if I'm zoomed in (100% or more), the brush makes its mark instantaneously with no lag issues. It's when I'm zoomed out (15%, 20%) that I have the lag- sometimes as long as 10 seconds. The further pulled out I am, the longer the lag.

Hi MEB, I uploaded one of those brushes, thanks for taking a look!

Hi mgicmarker,

Please check you PM.

Hello
I just bought Affinity Photo and I'm having this same problem - is there a way to solve it?
I've already changed the performance settings...

I´m working in a HP 4420 workstation - 32Gb
with a NVIDIA GeForce GTX 1050Ti, so I think it´s not a "power" problem

Thanks

On affinity v2 suite and still having the same problem on my desktop machine. I did not have this issue on V1 suite.

When selecting a PS brush, it takes about 10 seconds to register the selection.

When double clicking the brush to edit it, another 10 seconds.

When clicking each slider under dynamics, about 5 seconds per slider.

This is def a serious issue.

If anyone would like video of the issue in action, please let me know.

• Ryzen 3800x
• 32gbs DDR3 3200
• Radeon 6750xt

I am def not lacking in the specs dept.

Could anyone offer a solution or could affinity confirm its an optimisation problem on the back end?
