How to solve lagging in game?

Hi,

I am facing lagging in game. I feel the screen not run smoothly. Since I think my PC is quite high end spec it shouldn't be lagging and also I have play this Seal like years ago and it was smooth.
Any ideas?

Thanks :)

try to reinstall the game or check your internet connection ping

Try restarting your computer, seal becomes laggy when you haven't restart your computer for a long time.
