Ok guys, this is really strange. There's people that play the game with "potato" computers and doesn't have any problem.
Follow this instructions:
- Open the game
- Press SHIFT + G
- You'll see something like the image. Please, try every "Renderer" option. Try to do it in this order: OpenGL -> DirectX -> Software
- Every time you change the renderer, restart your game and try it. If you have problems, change the renderer again and restart your game.
- If the problem persist, update your graphic drivers and try again!
EDIT: Disable Power Save, too.
