Ps brushes slow by 2500

[DigitalVisuals]

Hi, this is a problem we have some time by most beta's that several PS brushes loading very slow, you can't change format of the brush when in use. 
This happend with mouse and/or painttablet.  The brush format in this case is mostly around the 2500 pixel.  Lower format around 1000 px is working perfect.
Tested in beta 1.8.0.555 with windows ink on and off

Hey studio97,

2500 pixels is pretty big to be brushing with. I've just created a 20,000 px x 20,000 px document in Photoshop and Affinity Photo and using a standard round brush I'm seeing very similar performance issues across both apps.

At this size brush, wouldn't you normally be stamping as opposed to painting lots of strokes? I'm not sure if we're just asking too much here.

Hi Chris, the problem with this brush we had several times in beta state, I think its a strange thing that maby will not be solved in short time. 
To your question about lots of strokes, no these are mostly stamp brushes, threes, water and so on. Yes I know I can make it smaller and edit it afterwards and almost they are PS brushes

Out of curiosity - did you ever had this working well at this massive size? Stamp or not - 2500 px is huge for brush. At this point youre better of doing some photo bashing.... Anyways - have you got that working well in the past?

Yes, I have it really working in the 1.7.3.481 without freesing the system or blocking other commands.

Ah, then clearly there is a reason to report that

Yep, 2500 is way too big (my first read was... ok, that post is crazy) , but not for stamping techniques. A lot of collage makers and other designers work so. And really interesting stuff can be done with those techniques.

Any performance improvement in the brush system is very welcome. What'd benefit your workflow would also help us digital painters using way smaller brushes. My machine typically wont allow me using more than 300px/400px brush sizes, with virtually any software. Which is kindda fine for my work, though. When needing that size of areas to cover for first concepts I just block and lasso fill even and whatever is faster, then is 100% typical brush work (but the activity is a whole other ball game).

I think you should be able to get away doing the odd stamp at 2,500 px but if you're working on a huge canvas where you're doing multiple stamps at that size then I'd expect a bit of a performance hit. 

I've just made a 10,000 x 10,000 px canvas and with a 2,500 px brush I can get away with 3 or 4 stamps before I notice the performance drop.

I can use them in 1.7.3.481 without to much slow down thats fine. But in the leatest beta's I see this drop everytime again sorry.

To close this one, after set Nvidia compute performing for AP to NO al the 2500px brushes are working on my system now.

Hello, studio97

Can You tell me how you did it, please...I,m struggling with that same problem

Thanks!

Look at these GPU card settings these are mine :

Thanks studio97!

I did that but the problem remained...what really resolve it for me was this:

I´m working with a xp pen artist tablet but the settings are the same. It resolved all of my brushes problems.

Windows INK is a great problem if you use a paint tablet. I have also done this for some weeks.

[Carlos Silva]

I saw it in the forum

but (for) now I think my problem is solved.

Thank You once more for your replies
