Help with DirectX 11.1 and Nvidia GPU Boost 1.0

[aram444]

Im on Windows 8.1 pro 64bit.
I have a EVGA GTX 660 FTW 2GB GDDR5 card as my GPU.
The card says it has DirectX 11.1 support but when I run dxdiag it says my DirectX is 11.0.
So my question is, how do I get DirectX 11.1?

Also for the Boost situation.
My card has Nvidia GPU Boost 1.0, but I don't know where to get it or how to use it.
I have GeForce Experience installed.

The card supports the DirectX 11.1 API but the actual feature level is 11.0. I remember seeing something about that on the back box of my GTX 780. As long as your DirectX is updated from microsoft http://www.microsoft.com/en-us/download/details.aspx?id=35 you have no issues nor are you missing out on anything.

And GPU Boost is a built in feature and is automatic there is nothing you need to do or install beyond the drivers. GeForce Experience has nothing at all to do with GPU Boost. What it does is increase the core and memory speed to a higher level when it is needed that is about it. It is nothing you need to worry about it is just part of the feature set of the card.

Alright thank you guys for your help. I wish I could pick both of you as solution/best answer but I don't know how to do that.

Cant do both, one is fine, there is is almost always multiple answers and contributors to a topic so whatever you feel is best just select.
