Yeah I had the DK2 and for LFS it was very well done support was tops.
For AC the resolution wasn't sharp enough for me... plus you really want some sort of HUD.
Well I do anyway.
Being in the car was epic, but you still want to see laptimes, fuel/laps left
I sold it and went back to 3 screens and then bought the desk/cockpit.
I'm waiting to see what AC puts in as proper support as off the forums it was half hearted... but that was 3+months ago...
Might have changed since then.
BTW - got the Beta of simvibe commander 4 and AC support is awesome. Just have to work out how to add rear traction loss, but feeling the road and ripple strips through the chair feels amazing...
