Pixel brush performance goes down as you zoom in

[LCamachoDesign]

It's what the topic title says, the further you zoom in, the slower the brushes becomes. If you're zoomed way out brushes perform between well to acceptable, depending on their complexity. As you keep zooming in, the performance drops further and further until they're unusable.

This is true even for basic round brushes, but it's more noticeable in complex brushes, such as Frankentoon's. I've also noticed it's worse if you're drawing over vector shapes, which is the whole point of these brushes. See the video for a visual reference.

iPad Pro 9.7" with latest version of iOS 12.4 and Affinity Designer 1.7.1.

I've tested and this also happens on Windows, the more you zoom the worse the brushes perform. But on Windows, especially on a desktop machine, the sheer processor power masks the issue.

Thanks!

Hi @LCamachoDesign,

Can you replicate this on a blank document? If not, can you attach that project file so we can try to replicate it? 

Thanks,

Gabe.

I can, it's just less noticeable. If you want the document anyway let me know where I can send it privately.

Thanks!

[Gabe]

Sure. Just upload it to our dropbox account: https://www.dropbox.com/request/IX2KlRnydRMEiNKG98QT

I've noticed something related to this. When you pan/zoom somewhere, the first pixel brush stroke is slow, but subsequent ones are reasonably faster. Don't know if this is already known or if it will help you.

Thanks!

We are aware of a very small delay after panning/zooming.

I am experiencing same issue with Affinity Photo/Publish on a 1080p document.

In the past I always thought my machine/brush was not usable because of the large latency. Now I realize if I zoom out it's noticeably faster.

It's hard to see from the video alone although it's already 60FPS - it's much more perceivable when you are actually drawing it with a tablet. I think it's expected because it's issue with hardware/software latency.
