You are able to control opacity, but I cannot seem to control flow? is there anyway to do this bar manually changing the brush dynamics?

Thanks for your reply.
What would be the best way of imitating the control of flow in PS? In terms of brush settings? I use a soft brush a lot, so it would be good top set one up that emulates one I have in PS

Hi Ωmega,
Welcome to Affinity Forums
GPU acceleration will come to Windows version as well. It's currently being worked on. Please bear with us.

Right. You're scaling that image up 6 times, and pixelation is expected. Not much we can do, as it's not a bug. Different software have different algorithms to resample. Below is an example from 
PS: Automatic

And AP: Lanczos 3 Separable

 

About all serious work I do in AP (compositing a bunch of images) includes resampling so this is important issue. Though I usually let export handle resampling which seem to keep quality reasonably good. These are hi resolution images though.

Did some testing, and in other applications scaling up with Bicubic Spline results in an even nicer/usable scaled up version than your Photoshop version.
Unfortunately, Affinity Photo doesn't give the user a choice in resampling algorithms when upscaling and rasterizing a specific layer.
I then attempted to upscale the original with the Resize Document option, and selected Bicubic as the resampling method. The result leaves a LOT to be desired of compared to any of the other apps I tested in (Krita, PhotoLine, Gimp).
In my opinion, based on my previous experiments with downscaling assets, and now with this particular upscale example, Affinity's resampling code base needs to be looked at again. It is a quite fundamental thing to get right. If other applications have no issues with up- and down-scaling, my only conclusion can be that something is amiss with Affinity's basic approach in resampling. The choices of resample methods in the preferences and document size dialog are fairly limited as well. For downsampling, for example, Lanczos and Bicubic are far from ideal choices, but no alternatives such as CatmulRom or MitchelNetravali are on offer in Photo.
As it stands, Photo is lagging behind all the competition in this area. Let's hope the devs will address this in an upcoming release, because it needs to be.

Can you attach the afphoto project file so we can have a look? Also, please attach the original images, unaltered
