Is there a way to force iGPU on 15" TB?

[thadoggfather]

I don't even own TB model, or a 15", or in the market,

but just curious if theres a gfxcardstatus out or in the works, used that back in the pre-retina 15" days

This will disable the iGPU, the opposite was what the OP was asking about:

Forgot to mention: I've read that several people still use gfxCardStatus so it should work.
I remember having issues when I last used it... Don't ask what it was though, been too long
