**OS** (e.g. Win11):

**PsychoPy version** (e.g. 23.2.3.x):

the update times for each frame become every 60 ms when I draw the polygons, making the presentation times inadequate.

How can I make everything more efficient?

(n is a list of 40 different polygons and circles is a list of 8 circles)

(f and d were set to 0 previously)

```
print(str(frameN), t)
if t < time_plolygons and f == 0:
for n in list_polygons:
n.setAutoDraw(True)
for n in list_intern_pol:
n.setAutoDraw(True)
f = 1
elif t >= time_plolygons and f==1 :
for n in list_polygons:
n.opacity = 1
for n in list_intern_pol:
n.opacity = 1
f = 2
if t < time_4dots and d == 0:
for circle in circles_dx:
circle.setAutoDraw(True)
for circle in circles_sx:
circle.setAutoDraw(True)
d = 1
elif t >= time_4dots and d == 1 :
for circle in circles_dx:
circle.opacity = 1
for circle in circles_sx:
circle.opacity = 1
d = 2
```
