Dirt 2 - am I using DX11?

Can I be sure I'm benchmarking using DX11 in Dirt2 demo? My understanding is that ultra setting enables DX11. My card is the 5850 extreme, and I've overclocked my 550BE to 3.8ghz from 3.1ghz. Demo score is 61fps avg, minimum 45.3 on ultra. Looking at my hardware settings cfg (screenshot pasted below), I noticed tessellation and water tessellation is 'false'. Those are DX11 things aren't they?
In my AMD vision engine control centre, under Tessellation, the 'AMD Optimised' box is ticked. If I untick it, the manual slider that says 'Level.... 64X' becomes usable, and the slider is at the far right '64X'. Or I can tick 'Use application settings' which greys out the level/64X. Should I use one of those and would that enable tessellation in the game and all games?

If I recall, dirt2 has different (sub) executable names for the different DX versions, so if you alt+tab out to desktop and check task manager, you should see which one it is using there. I don't have it installed on a DX11 machine to show atm, just what I remember from memory.
 
Run Afterburner with the overlay. u can go to the settings and make it say
"Direct3D 11 - 60 FPS", etc

I think it's the best way to be sure
 
Thanks. I've downloaded it.

I've ticked framerate in the monitoring tab and ticked 'show in onscreen display', but I get no display ingame.

Ah, got it. Had to reboot. Says D3D11, which I guess is DX11. But the demo doesn't save my graphics settings
each time I load it, and they're on high, not ultra. Thought the game only utilises DX11 with ultra settings, so how come
it says DX11?

Afterburner doesnt show certain features with ati cards? Could be a reason why it isnt displayed.
 
Ok, yea, I realise DX11 may not be such a great thing yet, but I'm still curious as to why tessellation is 'false' and why I can only get post processing to 'high' and not ultra, or quality '1' instead of '2' as it says in my config. With my O/C cpu and the 5850 it should be using DX11 right? It says DX11 in afterburner but I don't think it's using it. I've got a DX11 card, I want to see DX11 working damnit :p
 
TBH it doesn't matter. They are exactly the same. I think a couple of flags flutter a bit more or something. DX11 thus far is a total non event.

Colin McRae Dirt 2: DirectX 9 vs. DirectX 11
In a direct comparison the differences on the audience only become noticeable if you get close and pay attention - some more polygons in the right place make the figures look a little better. The flying flags are "nice to have” while the improved water visualization is really good: The car really ploughs through the water and builds up a little bow wave - additional particles on splashes make the whole scene more realistic. But the biggest difference between DirectX 9 and DirectX 11 is the illumination. Due to HDAO and nice Post Effects the visual appearance of Dirt 2 with DirectX 11 is less "overbright” and smoother. The more realistic look of the DirectX 11 version might convince some players, since there have already been mods for Race Driver Grid that were reducing exactly those warm colors and thus created a more real appearance.

Also the sharpness difference is very noticeable.

I think DX11 tesselates the puddles as you go through them , making a nice ripple/wave effect as well.
