Lagging brush packs

[khaynette]

The lagging on my raster brush packs is ridiculous. How can I fix this? I have a 32gb / 500gb , nvidia dedicated graphics, i7 , new, barely anything on the computer and I'm only using affinity program. How do I fix this?

Welcome to the Affinity forums, @khaynette.

Which Affinity program, and what release of the program, are you using?

Please give us details on the structure of your document, and include a screenshot of the complete application window and the Layers panel.

Is this happening with all brushes, or some specific brush pack?

@walt.farrell Every brush, worse with bigger sizes. I have pretty much a blank document. It fixed it for my first document after I disabled a couple settings in my graphics display, but now it's back to lagging. Rebooting isn't helping

24,000 x 24,000 at 1500 dpi? Why so big and high a dpi? Even an A3 size paper is about 4960 x 3508 at 300dpi (11.7 in x 16.5 print size) .

Since you are working in pixels, i assume this is for screen output. Try something more standard like a 1080p screen size or say 4k (3840 px x 2160px at 72dpi).

@BlueLiner , no it's because I want to be able to print with excellent resolution, at 60×80 blanket size and less. That, if i remember right was at 24000× 22000 (or around there) pixels. It is kind of random what i put in, but i want to make sure to exceed the minimum, since i find when i put patterns into the designers, it usually records a smaller dpi than affinity records it as. About half, usually. I need a minimum of 300dpi at that size. Perhaps it would be better if I created at the exact size for the biggest I would want to print, with a resolution of 300 dpi? Since it would just increase anyway if I sized smaller?  Or maybe at 600, since I'm concerned about why the designer cuts the dpi in half compared to what affinity says.

60" x 80" and the final print is a blanket? Here's one sites recommendation for digitally printed blankets:

 

Blankets will need to have a minimum DPI of 72, with a desired DPI of 100 and a recommended DPI of 300. Unlike most print products, the size and texture of blankets allow for the images to be below our typical DPI standard (300 dpi with a minimum of 150 dpi).

 

You likely do not need more than 150dpi for that sort of work. so 9,000 x 12,000 at 150 dpi.
