I draw hyper realism. That means at 2000% I draw a line at most 3cms long (most are much smaller). I fill in all the spots. Modify>shape is all greyed out for fills. I need at least 250 000 strokes to finish a piece of artwork. I am at maybe 4000. I am noticing incredible brush to eyedropper lag (I switch between the two constantly because i am drawing based on color palette. I feel adobe severely limits artists, making each switch from eyedropper to brush 4 to 5 seconds long between each stroke. I need a fix.
