affinity designer pixel brush lags when i use it in large sizes.

[romaz2]

Hi

i am having trouble using affinity pixel brushes with high sizes (2000 pixel or more) the painting become slow and lagging it takes few seconds to see the brush paint.

for example, both brushes dense wash and salty wash are some of the brushes i having trouble with.

i tried to turn off compute acceleration without any improvement, what i can do to improve the speed of brush?

i have to use big document 36 X48 inches, and i am using a laptop with windows 11 OS with the following hardware:

 

 processor: 12th Gen Intel(R) Core(TM) i7-12650H   2.30 GHz

RAM: 16 GB

GPU: G-force RTX 3060

SSD hard disk

please help, thank you

I am surprised that it lags for only a few seconds.

Hi romaz2,

With such a large brush, increasing spacing can reduce the load on your computer.

thanks for your reply LEE_T, so you say it is normal to have this lag ?
