Intel video is normally working out of the box, but for newer
hardware you also need up to date software.

So if you are on 7.5, try upgrading Jessie.

For example, I couldn't get 3d accelleration working on the integrated
adapter of my i5-4570S on Debian 7.3, and upgrading to testing
solved it.

You can check if it's the same problem with:
$ glxinfo | grep renderer

If there is something with LLVM in the output, it's not working and
falling back to software emulation. While you're at it, you can also
try glxgears.
