particle system run very slowly

[yonghuming]

Describe the bug simple particle system run slowly

from p5 import *
from random import randint

class Ball():
    def __init__(self):
        self.x = randint(0, 800)
        self.y = 0
        self.vy = randint(1, 5)
    
    def update(self):
        self.y += self.vy

    def display(self):
        ellipse(self.x, self.y, 100, 100)

    def run(self):
        self.update()
        self.display()
        
balls = []


def setup():
    global balls
    size(800, 600)
    balls = [Ball() for i in range(100)]
    

def draw():
    global balls
    [ball.run() for ball in balls]
    background('red')

run()

To Reproduce just run the code above

Expected behavior as least fluently like https://editor.p5js.org/yonghuming/full/BDkk1FPlP

I think this issue will be solved once skia is implimented #212

[yonghuming]

skia

opengl is powerful, why p5py so slow? pygame have better experence with similar code, also arcade. mabye there are ways to figure it still use opengl and glfw

[yonghuming]

skia use glfw

You can try the new experimental renderer or visit #357. I tried the above example and it runs fine for skia
