Benchmark Results: DirectX 11 Versus DirectX 9 And 4x AA

With DirectX 11 taking a colossal performance toll, what happens when we combine it with 4x AA?

It looks like these new DirectX 11 cards are quite efficient when it comes to AA, as the results don't change all that much. Only the Radeon HD 5750 and 5770 really suffer, but 1920x1200 performance remains playable, if not ideal. The Radeon HD 5850 and 5870 cards continue to provide playable performance at 2560x1600, which is quite an accomplishment. Only the Radeon HD 5850 cards in CrossFire are able to provide the smoothest minimum and maximum FPS results, however.

    I have to say, Dirt 2 is a great game if you like the rally/baja type car racing. Regardless of the graphics differences the game play is simply fun. It's not "real to life" like Forza, but it is a blast playing if you like sliding around corners on track that's not necessarily pavement.

    Looks good, gotta be honest though I probably wouldn't see much of a difference if I just played the game without taking a good look at stuff. Maybe except for the water.

    One down, one or two to go ;)

    Until DX11 does not become mainstream (eg. 90% of the users will have DX11 capable cards) you can't expect to see differences between DX11 and DX9/10 modes. Why? Because they won't make games where one player sees something and the other does not, to the point that will actually mean something and affect the gameplay.

    So anyone that bought the cards for DX11 will not get anything extra from the DX11 code path. No developer that wants to sell a game would code it so that you'd need a new card to play the game. They would not shoot themselves in the foot.

    DX11 is now in the position PhysX was, and I'm not necessarily speaking about the CUDA PhysX version, but the original PhysX by Ageia, when you needed a PCI card for it. It had and still has great potential, but you can't use it to it's full extent until people embrace it and make it mainstream. Until then, all the developers can do is to use certain features here and there, so that it gives you a glimpse of what it could be, but not so much that it makes a difference and modifies the experience too much. They just don't want to give up customers, it's not just that they don't want to use the technology.

    And when DX11 finally becomes mainstream, in 6-12-18 months, the current DX11 cards will be nearly obsolete performance wise... truly tragic. But that's the way the cookie crumbles...

    It's a bit of a troll-ish post (it may seem that way, if you have an ATI DX11 card), and I will get "-1" all round but it's the truth if you think about it from a safe distance. Too bad you... yes... you... the one clicking the "Useless message" icon, won't even get to this last paragraph.

    Dirt 2 uses a DX 9 engine, so I guess this is not such a big surprise, although I've expected more from DX 11 integration, actually **allot** more, considering that the game was marketed as the first DX 11 title out there.

    It's rather disappointing to see such small visual differences between DX9 and DX11 versions, even though I've never expected rather major ones from this title.

    My hope is that DX 11 will become mainstream very fast, and developers will focus on getting the most out of it soon. Congrats to all that got DX 11 cards this christmas(me included). The DX9 performace is great and the fact that DX11 gains market share is even greater.

    I think, I'm not sure though, but I think he is somehow trying to say that in the 'future' your DX11 graphics card may need to be upgraded to a more powerful DX11 graphics card. Something that has been happening with every graphics card for the last 20 years. I am not sure I can deal with all the tragedy.

    I could be wrong, but i think that the only game that will probably show the full potential of DX11 it´s going to be Crysis 2, so prepare your wallets for the PC upgrade...
