Maple Story Constant Freezing

[果盘男孩儿]

As the title said, I had very bad issue on playing maple story. The game constantly freeze and no responding and turn back to normal after few seconds. I have tried very methods that I found from internet, but the issue still exist on my PC. Anyone got idea for that, cause I can't bear the serious lag while I playing the game
