Hi there good folks in the Affinity forums,
first of all, I want to say, that I do like the software very much and I really try to find a solution for my problem here. I've seen variations of this issue in other threads before, but but it seemed, that there is no solution to this.
Here are my problems:
In Affinity Photo and Designer (Pixel and Designer Persona) I experience serious brush lag and all in all performance issues. This happens with brushes in all sizes and complexities, even with the standard default pixel brush.
When I rotate my canvas, raster based areas are victim to very terrible anti aliasing problems.
Here you can see an example of the anti-alias problem, you can see it in my red and green sketches especially, but also in the photo reference on the canvas. This happens with all kinds of brushes:
Here is a video from AP (happens in AD in the same manner), where the brush lag is visible very clearly. I realize, that in this instance the lag is connected to fast and short brush strokes, but this happens no matter what brush type or size I use:
Affinity Photo 2021-03-10 17-16-13.mp4
My specifics:
I am using a Wacom Intuos Pro M on Win10
CPU:Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz 2.59 GHz
GPU: GeForce RTX2070
32GB RAM
I also permitted the software to use more RAM and set the Geforce GPU as default.
I really wonder, what the issue is here, since the PC should be more than able to run AP+AD without any performance issues. But when using the software I can clearly detect spikes in CPU and GPU usage in my Task Manager.
I'd really love to use Photo and Designer as my dedicated painting software. But as it is right now, I'm having trouble to perform very simple tasks with it.
Thanks in advance for your support, I really hope there is a solution to this:)
Best, Garf
