Why doesn't LR 4 use the GPU to speed up the develop module?

LR 4 (and LR 3 as well) are very slow compared to competitor products (e.g. Phase One and even Photoshop). For example, there is often a delay of 1-2 seconds when you adjust a slider in the develop module. This is problematic because you can overshoot your desired adjustment and then you have to wait for LR to catch up before you see that you've overshot the mark. Then you have to interpolate between where your slider was and where it is now to predict the right setting and wait (again) while LR renders its image. If it used the GPU, the image rendering would be much faster.
