Hello,
I've downloaded one of the beautiful samples "Tiger Club", that is a vector artwork, 100 Mb.
1) Just scrolling/zooming through the artwork causes 100% CPU spikes and the whole system (like audio being staggering cause of that) to lag at those moments. My monitor's resolution is 3440x1440, editor is at fullscreen. The resolution (as I've discovered) is the part which presumably causes these lags. Resizing the editor window to something like 1920x1080 and scrolling through the same artwork causes spikes up to 50-60% only, and the whole system doesn't lag anymore. Please bear in mind, that I have latest i7-6700 as well, which is 4 physical cores, 8 in HT. I thought Affinity does GPU acceleration though?
2) Opening more complex artworks tend to increase the overall stability of the editor, it's like... Imagine having an old browser which is running all tabs as one process, same lag here. I think Photoshop tends to work with multiple huge files OK.
3) Once again, panning the artwork almost always isn't smooth, but choppy.
Thank you for such a nice, beautiful editor on Windows! It's still *much* smoother and faster than Illustrator, but I just hope I can listen to music while working fullscreen without any hassle =)
