Is there a way to flip a bit such that RaceRender requires the discrete GPU in a MacBook Pro? According to Activity Monitor it does not require it. There does appear to be a small RaceRender rendering time improvement when forcing the Mac to run all apps with the discrete GPU over the integrated. But would much rather RaceRender require it so I don't have to manual use the higher performance GPU (and its power consumption) for when I'm not using RaceRender. See the image below:
