Affinity Photo brush anti-aliasing?

[nickburnsap]

I've just made the switch from Photoshop to Affinity Photo for digital art, and while I'm super pleased with virtually everything, I have noticed a - problem? - with the brush rendering. It appears really aliased and jaggy.

Now I know Photo is working with rasterized pixel based images, but it just seem aggressively pixelated. By contrast Photoshop seemed to have some kind of smoothing on just the rendering of it. Am I missing something? Is there a brush setting or the like that I have to flip to smooth the rendering of brush strokes? Or is it just that Photoshop has some kind of secret sauce that makes even raster brushes look smooth?
I have the performance settings set to maximum quality (Bilinear, 30GB RAM etc etc).

The attached image is from a 1920x1080 150dpi document. I believe making it a 300dpi 4K document would help somewhat, but when I tried that on another drawing it still didn't help. Even when I'm zoomed all the way out it still appears like that.

Any direction would be greatly appreciated, I'm happy to troubleshoot the issue as well.

Cheers,

On the brush hardness set it to 99%

Awesome! That helped half way, now when I'm zoomed in its not nasty looking, thanks!

Though when I'm zoomed out, the effect still appears.

It's a difficult task for programmers, but very important. 

Good anti-aliased brush algorithms can be found in open source software like
Krita or AZpainter2 (https://github.com/Symbian9/azpainter).
