Jerky fps when Intel graphics is selected from graphics option menu.

less Jerky fps when no Intel graphics is selected from graphics option menu.

As of Mesa 5c9e0ad5fddf216921703a0aa9c911a51226cdfd this is fixed.

fps is smooth when Intel Graphics is selected from Graphics Option Mesa in the game.
