Brush lag/update is very slow.

[gidkid]

I've tried restoring defaults, using openCL, turning windows ink on and off etc. but no mater what my brush in Affinity Photo is REALLY slow to update. Doesn't seem to mater if it's a basic brush or a complex one. Size only effects it somewhat, but even a tiny brush has issues. Canvas size doesn't seem to be an issue. a 2k x 2k image has the same brush issues as a 5k x 5k.

With a mouse it's a little slow. With my wacom tablet, it's nearly unusable. Same canvas size and similar brushes in the ipad version works flawlessly. Photoshop on the same PC is plenty fast.

Oddly using a raster brush in affinity designer has none of these issues or they're much less so.

Any ideas of what to try to get the speed back up?

Hi Gidkid,

It may be worth downloading the below beta to see if this solves your issue at all.
https://forum.affinity.serif.com/index.php?/topic/156274-affinity-photo-windows-customer-beta-11051282-rc/
If you into the apps preferences and under the performance tab try changing the view quality dropdown to nearest neighbour does this issue still occur?

Thanks

Hi Callum,

I loaded the beta at defaults and over all it was a HUGE improvement. I looked in the prefs and see that by default most of them are turned up to their highest settings.

Many of the brushes seem much faster even at very large sizes (1-2k). A few brushes are still really slow even at default sizes and have that faceted look when drawing fast strokes like the Matte Acrylic 01 brush (first in list by default AFAIK) and the Comics Ink brush. I haven't tested them all but maybe there is a common feature enabled for some of them that is still slowing things down?

Nearest neighbor didn't seem to change things much for those brushes.

Over all though it's much better than before so this beta is looking really promising on that front. 👍
