Laggy Game Movement

By using pygame.time.get_ticks.
This is how I normal handle it. This handle three different ways. one shot timer, repeat timer, and trip counter timer.

class Ticker:
    def __init__(self, ticks, interval):
        self.tick = ticks + interval
        self.interval = interval
        self.count = 0

    # One Shot Ticker
    def elapsed(self, ticks):
        return ticks >= self.tick

    def reset(self, ticks, interval=None):
        if interval:
            self.interval = interval
            
        self.tick = ticks + self.interval

    # Repeat Ticker
    def tick(self, ticks):
        if ticks >= self.tick:
            self.tick = ticks + self.interval
            return True

        return False

    # Trip Counter. Keep track when interval are low. 
    def tick_count(self, ticks):
        self.count = 0
        while ticks >= self.tick:
            self.tick += self.interval
            self.count += 1

        return bool(self.count)

In main loop. You can do something like this.

ticks = pygame.get_ticks()
ticker = Ticker(ticks, 2000) # 2000 milliseconds equals 2 seconds.

# In Main Loop
ticks = pygame.get_ticks()
if ticker.elasped(ticks):
    ticker.count += 1
    if ticker.count < 2:
        # set next ticker if needed
        ticker.reset(ticks, 3000)

if ticker.count == 0:
    # draw your stuff
elif ticker.count == 1:
    # draw your stuff
