Hell both shots look good


I am really digging the sun flares and the heat effects from the cars exhausts

Not too much of a difference. But the points of interest are the smaller rocks, the large tree, and the small tree. If you compare them the lighting/shadows is WAY better. But really, in a game like this, you won't ever notice them because you will be driving so fast.

Some minor differences can be spotted in the lighting effects, though. Both DirectX 9 and DirectX 11 mode do an admiral job of mapping the sunlight onto the surfaces of the cars. However, we felt that Direct X 11 rendered the beams from our local star in a slightly more accurate and cleaner fashion, making the light sourcing look more believable. Most noticeable is the cleanness of the shadow, particular when it's cast by the rear spoiler onto the bodywork - in DirectX 9 mode, the shadow has a chunky edge, whereas in DirectX 11, its edges blend away smoothly. Still, the differences are marginal, not easy to spot and not worth a 30fps cut to your frame rate.

Intriguing, isn't it? Except the tessellation effect when the water hits the car, you have huge difficulties identifying the differences. If you look and Dynamic Range, sure the DX11 images are sharper but then you have to analyse the light flares and the rest and then you spot the differences. Maybe a problem with the demo? Maybe Dirt 2 does not show the real potential for DX 11. Do we need to wait for Crysis 2 or 3 whatever it will be called?

Wait until games are built around DX11. Dirt2 basically just had some last minute add-ons.

We were expecting the lovely rippling effects in the flags to vanish without tessellation to smooth out their supple curves. However, all of the flags in the demo rippled just as convincingly in DirectX 9 mode as they did in DirectX 11 mode. Likewise, all of the textures looked the same too. You'd need a seriously keen eye and brown paper envelope full of cash from one of the creators of Dirt 2 to notice any real difference between textures in the two versions of DirectX.

picture 3 looks like its getting swarmed by a plague of fiberglass sheeting

other than that i see no diference
This really isnt the game to take advantage of DX11 features as you will be moving so fast you wont have a chance to even notice. The shadows under the small rocks look MUCH better and the tesselated water looks great too. Overall I think I would use DX9 in this game but if it was a FPS I would definitely use DX11. In the last 2 screenshots I notice a huge difference in the shadowing of DX11 and DX9. The ambient lighting really makes it look much more real.

Yes but the BIG question is when are games going to be built around DX11,maybe 2/3 years time when the next generation of consoles are out.no developers are going to write games in DX11 when it would not work on the current generation consoles,and as we all no that's what most developers main market is the CONSOLES.

Sad but true.

I am waiting for steam to release the full version and will make my own tests.
