Question

我目前正在使用Pygame编写游戏，一旦我实现了主菜单，我的游戏的FPS被除以2，什么可能导致这种滞后？（我在谈论播放时的帧速率，当主菜单不可见时）

主菜单有代码（点列表是多边形显示当前选择的点列表）：

import sys,os
import pygame
from Hud_implem import *
class MainMenu(object):
    def main(self,screen):
        self.buttonlist = [[0]]
        self.buttonlist.append(self.pointlist((58.104,32.148),(69.396,23.915),(69.369,30.296),(58.104,38.630)))
        self.buttonlist.append(self.pointlist((58.104,41.407),(77.229,27.296),(77.229,33.777),(58.104,47.888)))
        self.buttonlist.append(self.pointlist((58.104,50.037),(74.187,38.185),(74.189,44.666),(58.104,56.519)))
        self.buttonlist.append(self.pointlist((58.104,58.704),(66.396,52.593),(66.396,59.074),(58.104,65.185)))
        clock = pygame.time.Clock()
        screen_image = pygame.image.load(os.path.join("Images","Title Screen.png")).convert_alpha()
        screen_image.set_colorkey((193,56,57))
        screen_image = pygame.transform.smoothscale(screen_image,(SCREEN_W,SCREEN_H))
        selection_layer = pygame.Surface((SCREEN_W,SCREEN_H))
        selection_layer.fill((255,255,255))
        selection_layer.set_colorkey((255,255,255))
        selection_layer.set_alpha(100)
        self.selectioned = 1
        self.movecountdown = 0
        while  not started:
            dt = clock.tick(60)
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    return
                if event.type == pygame.KEYDOWN and event.key == 13:
                    self.get_pressed()
            screen.fill((49,103,124),((0,0),screen.get_size()))
            self.get_selection(selection_layer,screen,dt/1000.)
            screen.blit(screen_image,(0,0))
            pygame.display.flip()

    def get_pressed(self):
        if self.selectioned == 1 or self.selectioned == 2:
            #started = True
            Game().main(screen)
        elif self.selectioned == 4:
            pygame.quit()
    def get_selection(self,layer,screen,dt):
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_UP] and not self.movecountdown:
            self.selectioned += -1
            self.movecountdown = 0.2 #NOT 2 DISPLACEMENT AT A TIME
        if keys_pressed[pygame.K_DOWN] and not self.movecountdown:
            self.selectioned += 1
            self.movecountdown = 0.2 #NOT 2 DISPLACEMENT AT A TIME

        if self.selectioned > 4:
            self.selectioned = 1
        if self.selectioned < 1:
            self.selectioned = 4
        self.movecountdown -= dt
        if self.movecountdown < 0:
            self.movecountdown = 0
        layer.fill((255,255,255))
        pygame.draw.polygon(layer,(0,0,0),self.buttonlist[self.selectioned])
        screen.blit(layer,(0,0))


    def percent(self,percx,percy):
        return (float(percx/100*SCREEN_W),float(percy/100*SCREEN_H))
    def pointlist(self,topleft,topright,bottomright,bottomleft):
        topleft = self.percent(topleft[0],topleft[1])
        topright = self.percent(topright[0],topright[1])
        bottomright = self.percent(bottomright[0],bottomright[1])
        bottomleft = self.percent(bottomleft[0],bottomleft[1])
        return [topleft,topright,bottomright,bottomleft]


if __name__ == '__main__':
    global started
    started = False
    pygame.init()
    pygame.display.set_caption("Project Swordman","Icon.png")
    pygame.display.set_icon(pygame.image.load(os.path.join("Images","Icon.png")))
    SCREEN_W,SCREEN_H = 1366,768

    #screen = pygame.display.set_mode((SCREEN_W, SCREEN_H),pygame.FULLSCREEN)
    screen = pygame.display.set_mode((SCREEN_W, SCREEN_H))
    MainMenu().main(screen)

什么导致滞后（Pygame主菜单）？
