I've been attempting to get geometry shaders working, however it tosses me a compilation error stating:
No subshaders can run on this graphics card.
I believe I'm running Unity Pro at the moment (Help->About Unity says "License type: Unity Pro"), so that's unlikely to be the issue.

Now I'm having trouble grasping the issue. I've got a Radeon Sapphire HD 5770 with the newest Catalyst drivers installed, as well as DirectX 11. But what's confusing me is that dxdiag claims my DirectX version is 11, while CCC claims my Direct3D version is 9.14.10.0969. Is the D3D version supposed to match that of DirectX? I've run DirectX 11 benchmarks and they appear to work, so I'm fairly certain that's not the issue.

Any and all help is appreciated.
