Don't know if you've fixed this yet, but i had the exact same problem. Almost took the game back to the shop for a refund because of it. Finally found on the internet that you can fix it with the following: When your game window appears, click on the "configure" button before starting the game. Click the box that says "V-sync", effectively turning it on. That's it. After that start the game as per normal. It worked for me just fine. Hope that helps
