Well I can agree with both sides. Of course it has some awesome features (and some stuff is much faster aswell)
but there aren't a lot of people around here who actively work with advanced graphics-technology like this.

I am very interested in Dx11 support but as I've already said there are not that much people who
would have a lot of benefits from this feature.
And also Acknex (in some parts) is outdated and still has other, more important stuff to be improved.

...oh, and: "Who doesn't"* ;P
