From the developer:
GPUInfoMenu can now toggle between dynamic GPU switching modes and the integrated graphics on new Core i5/i7 MacBook Pros. This functionality is triggered by a menu item (off by default). There is a single toggle that switches the GPU to Intel graphics when the laptop switches to battery power and back to standard dynamic switching when on AC Power
