I have Deus Ex: Human Revolution and playing it on 9600GT. I donít have the graphics card which is supporting DirectX 11 with it. I am right now using direct X 10 card with it. There is the feature known as the Tessellation which increases the level of fineness in the games. So I want to know that does the tessellation effect in the DirectX 11 will be used for the game. If yes does it cause more recourse in the game? If the tessellation is supported in the game then only I am interested in the upgrading the graphics card to the latest DirectX 11 card.
