Is there any third-party application or terminal command to change the actual resolution to 1440x900? This is for when you want the same graphics performance offered on the low-resolution models. This would not be scaled (so none of the retina graphics would be used). Every four pixels would act as one pixel, and the screen and everything on it would look and act like a normal 15" MacBook Pro, with the same performance as well, because (and I cannot make this clear enough): I am talking about changing the actual resolution to a fully-downgraded version for intensive operations where retina quality would be detrimental to performance, and normal resolutions would be preferable (1440x900). With no scaling or retina graphics used like it offers out of box. Is there a way to do that? Thank you.
