Description of the warning/error

Threaded screen capture is very laggy while gaming

Full message

When i create a threaded class to capture the screen as fast as possible, it is makes my screen resposiveness very laggy... I can not play well. After making a sleep : Time.sleep(0.5), it does not slow down gaming, but reaction time for leds is too slow...

Pseudo code:

class Ambilight(Thread):
def __init__(self, LightController):
  self.screen = mss()
  self.imageCaptured = None
  self.LightController = LightController

# ...

def run(self):
 while True:
    self.imageCaptured = np.array(self.screen.grab( self.screen.monitors[0]))
    self.LightController.ImageUpdate( self.imageCaptured.copy() )
